I just read the actual Dave Brown article ... This guy is very sneaky and devious in what he is doing .. basically , he is not really stating anything too direct about jets in general, but is implying a lot indirectly, and ralying the "turbine ignorant" majority of the AMA membership against us, without any backing knowledge or facts ... I am very dissapointed with all this BS.... Its unfortunate that majority of the AMA membership might never get to hear our side/facts of the story, because the AMA would never publish an article in their mag about the real facts and statistics ... I can already see the coments at the field from all the guys with their telemasters and avistars, and how our local field will need to ban turbines to go allong with Dave Brown, our honorable AMA president .... While they are at it, they will ban turbine helicopters too "just because" .....

The more i see what is going on, the more i am realizing that some of these problems wont go away untill the ignornat and stubborn just basically die off ....

Wojtek brings up a good point. No one will ever hear the truth. Does anyone know that guy (Jim Hiller) that writes the Jets column in Model Aviation, the column that only appears every three months or so? We need to get that guy to tell it like it is an rebuff what DB has said with the facts. How 'bout it? Or is he in DB's pocket?

a top "super waiver" is really the long term solution....


A long term solution, if, and only if, the President and EC allow relaxation of the speed and weight rules for those "super waivered", and there is nothing in their current stance that would suggest that is going to happen......


Not to mention the major PITA implementing and enforcing that system..... there are jet guys in Wisconsin that never plan to travel to some out-of-state location, to meet up with some super-certifying TCD just to obtain a "Super Waiver" so they can fly their BVM Big Bird or Bandit at 200MPH, which they may have been doing successfully long before the guy signing them off even knew how to spell turbine waiver......just another level of discrimination, IMO, which, like screwing with the 0.9 T/W---200MPH rule at the November 1, 2003 EC meeting, could have significant unintended consequences......>as you noted "this speed limiter thing is a real mess" Ahhh.....self-induced, might I say....the TRC didn't think this one out to it's logical conclusion......>that someone on the EC was going to ask those embarrasing questions you mentioned in post #118

Wojtek brings up a great point that this article will breed local flying clubs to ban turbines. The average joe knows nothing about what we do and will be having us banned from our field because of these kind of publications.
We are only 750 in the US, but how many of us are there worldwide? Has there been any catastrophe worldwide to warrant restrictions to turbines? It had always been my impression that there arent any restrictions on turbines in other countries and I have never heard of any significant loss.

Lee,
How about the guys that crash in the traffic pattern just simply trying to land or takeoff. The guys that use cheap servos that fail or arent powerful enough resulting in a crash. The guys that forget to charge either the radio or the ECU pack resulting in a crash. The guys that fly brand x ARF's that turn into confetti at any speed above 150 or two g's(crash). The guys who takeoff with reversed ailerons(crash). The guys that forget to refuel(crash). The guys that use Home depot quality adhesives(crash). The guys with actual radio failures(crash). The guys who just plain old dumb thumb it(crash).
And you think the answer is to slow down a guy with a Super Bandit who is under complete control at 220 with a manufacture's VNE of 250, and slow him down to 200 is the answer. I guess I dont understand your logic

Speed limiters may be part of the sollution, but they are not the sollution. Tier system gets my vote. my .02

Well I am just an average "JOE" as someone put it that has been flying for 30 years would own a turbine tonight if i could afford it. I know and see the benefits and advancements for the average "JOE" because of the level of eguipment ,building methods, and technology that has been a direct result of the need for speed and precision that the jets demand. I for one applaud the people, groups and companies that have allowed major advancements to try and keep safety the most important criteria and that has trickled down to people like myself and all modellers.
I knew when I saw and heard my first rc jet in Dallas Tx. that the hobby had just reached it's highest challenge in an attempt to replicate full scale and you could see things changing almost over night. It has been amazing to see the advancements made by dedicated modellers in turbines, helicopters, pattern and now 3D and to know that almost everytime I open an RCM or MAN magizine there is something NEW that has been a direct result of people like you guys which only makes the hobby safer and more affordable.
As far as the 200mph speed limit goes, what if the NHRA had told Kenny Bernstien that 300 mph was impossible and unsafe...does anyone think that would have stopped him..or anyone for that matter. I don't know about you guys but when someone tells me I can't go that fast it just fuels me to go faster and to push the limits even further. Is the world any safer from a jet doing 200 or 250 or 300mph...hell no, I just can't see much difference.

Hello Ad Clark III whoever you are?

I couldn't agree with your objective logic more, than if I'd said it myself ----- OK a 10 tier system if that turns your crank. Maybe I'm wrong in what I perceived Dave was saying ---- my interpretation is WE created the dreaded 200 number years ago ----- and so far the underwriters have been satisfied with us all things considered ----- now Dave / underwriters see a change being requested i.e. latest JPO proposal. We couldn't have had politically chosen poorer timing in my opinion, insurance companies are nervous as hell these days ----- and there answer has always been to raise the premium rates if in doubt.

I love these nameless comments ------ Boss 248 whoever you are ---- Ask Kenny Bernstien and NHRA how much the insurance premium costs for him to do his thing. Hey, guys I think WE are missing the point big time Dave is the President of the AMA I believe he is speaking for the AMA. Most of our Jet Rally organizers rely on AMA site insurance to hold our Rally's --- I believe this is the line-in-the-sand Dave is referring to. How much money are 170,000 of our fellow modelers willing to come up with to support the 2% -------

Part of the problem Lee is your info is incorrect. According to my info, ALL of the changes proposed were run past the AMA Safety Committee, the AMA's Insurance people, and the AMA legal dept and they all found no problems with the new rules, yet Dave has decided that all these learned people, in addition to the EC, were flat wrong, and HE is right.

The 200 mph issue is silly in my opinion. There are FAR more dangerous things than a 200 mph capable aircraft. We need to police ourselves and take away waivers from people who should not be flying jets. I have more problems with a guy who has the ability, but not the brain power. The guy who is a good pilot, who makes poor decisions (like flying anyway after have had radio problems during ground checks).

People who have demonstrated ability to competently control a jet aircraft should not be penalized for those who don't.

I'm one of the "average Joe's" you speak of. I had a thought to contact my District VP about what is being discussed here. I don't fly any turbines or duct fans or anything requiring the skill or money they demand. I am interested in pursuing them in the future though. Anyway, here's his response to me in a private email. Since his reply was understood to be between only the two of us I will refrain from using his name. Notice that in his response NO ONE from my district had contacted him to object to the what is going on. I think maybe the suggestion that you contact YOUR district VP will do far more than ranting here in RCU about all us "average Joe's" cramping your style.

Respectfully,

Mark

. . . I think Dave Brown's concerns regarding our insurance situation are
valid. Our track record over the last few years has been poor, at best, and
last year we literally went to the eleventh hour before we even got a quote
on coverage for this year. This along with the hypothetical scenario of a
highly visible incident, resulting in government regulation of our sport, is
what I believe are driving Dave's comments.
Even though the turbine community has a good safety record I think
common sense would dictate that the risks associated with a turbine model
capable of traveling at 200 mph, carrying one or two gallons of jet A, are
greater than most other types of models. The risk of a fire is certainly
greater. Witness the incident at Floyd Bennett during the Big Apple Jet
Rally in 2002. What other type of model crash would result in that explosion
resulting in debris damaging models on a flight line almost a couple hundred
feet away? So, yes, I think there is a higher risk when flying turbine
models.
The question becomes how can we minimize that risk while still allowing
for the enjoyment of the discipline along with not stifling technological
advancements associated with turbines. I'd prefer to see us use pilot
education and ask the turbine community to help by policing themselves in
trying to reduce our exposure. I'm aware that some think the turbine guys
haven't done a good job in assuring compliance with the regulations. While
that may be true somewhere I think most turbine pilots do a good job
regarding safety concerns. Witness again the turbine group that flies at
Floyd Bennett.
I thought, as a package, the new proposals were good work. I had some
concerns, but as a package, I think they raised the safety bar. I voted in
favor of them. Of the three or so concerns that I believe Dave Brown has,
his biggest concern is the lack of requirement for some sort of speed
limiter. Since probably only a handful of turbine models are capable of
approaching 200 mph, and because we were told that there was only one
aftermarket speed limiter available (and it has reliability concerns), I was
reluctant to endorse the requirement for one in all turbine models. What
created much of the flack after the initial vote was that AMA was contacted
by more than one manufacturer who indicated that they could produce a
reliable unit. With this new information, Dave Brown asked that we vote to
hold off on implementing the new turbine regs until we can gather more
information on these manufacturer's claims. Since nobody in our district
objected (directly to me) to the requirement for a speed limiter on models
capable of reaching 200 mph, and all those in our district that have models
capable of reaching 200 mph are already using speed limiters, and would
continue to use them whether they were required or not, I voted in favor of
delaying implementation pending further info. Based on the current input
that I have received I would probably favor speed limiters on turbine models
that are capable of approaching the 200 mph speed limit (not ALL turbine
models) assuming a reliable, working unit is developed by somebody.
Hope I've answered most of your questions. If not, let me know and I'd
be glad to give you a call. It's hard sometimes to discussing things like
this in an email exchange. I know what you mean about the only times you
hear about AMA. That's exactly one of the reasons we created the District
Fly In here in our district. Let me know if you'd like me to give you a
call.
Dave

Hello Doug,

I wish Dave Brown would jump in right here and help us all read between the lines of print and sand. He is the AMA president at this point in time, and as you can see presidents of any organization do have power. If the facts are as you say Doug, if I understand you correctly you suggesting this is a personal thing? I guess I just don't want to believe that is the case.....

Hi,
As a follow up to my previous post, I called AMA and talked to Yolanda about buying a page in MA to reply to DB's editorial. She said she was going to check with Bob Hunt on what the procedure is, and after being on hold for a short time, said I should write a letter to the editor and the editor of MA would take care of it. Of course this did not answer my question, besides there's no way DB is going to allow any correspondence to be printed that is critical of him. I'll wait until after the holidays are over and try to talk to someone who can give me an answer.
Looking forward to WRAM show!
Regards,
Jon

I've been reticent to actually post, but haven't seen this angle yet and wanted some other views on it. I do professional safety risk management and get involved with insurance risk management.

Seems we can also look back at this from 2 views: 1) Safety operations/rules modelers employ; I think this will flush out well enough after all the dust settles and 2) Interaction with insurance.

It's the interaction with our underwriters at renewal time that concerns me. Everyone knows about the insurance "woes" that are occurring and one of their earlies employed tactics is to limit there exposure to liability (risk management). Easy enough, from their stand point; "you want the same rate or cheaper on your premiums, then why don't we look at excluding coverage on certain activities involving high performance models". The "line in the sand" has to be drawn somewhere, right? We, as the collective modeling body, can't reasonably cover ALL activities conceivable. It's at this point the bargaining begins when you renew insurance-I didn't take mold coverage on my house, it's too expensive for the return and preventable. Will "at risk" activities be separated out as a rider? Who will make this decision when the next renewal comes about?

By the way, there ARE techniques for quantifying relative risks and loss potentials due to our different hobby activities - they just take time and effort to employ by a professional - I used to do it everyday when I worked in the chemical industry as a safety engineer performing hazard analysis and the insurance industry employs various models as well.

Geesh! Just as I got all invested in jets, ducted fans and my first turbine and got the baby to sleep through the night...sigh...

I in no way intended for my average joe comment to be condesending. I meant to imply the other population that doesnt take interest in the jet section of the hobby and the only info they have being heresay. I in no way consider myself to be an elitist. If i had no knowledge of jets and the effort that is engineered in the making and constructing and quality that goes into a jet with the very best materials and the very best electronics and had to make a decision regarding a 60lb twin turbine airplane that goes 200 carrying 3lbs of fuel, i might be concerned of the potential for a problem and want to over regulate or limit this kind of model. Example: dont ask me about making rules for rockets, because I have no knowledge of these what so ever. Why should the opinions of people be solicited that really have no information to base their decision on?

Mark,

I (and others) have contacted Dave about this when the EC first met, and based on the emails he's provided me, I believe he's "in the loop" so to speak. He indicated to me that he would support limiters in aircraft capable of exceeding 200mph, and that it would impact a relatively small amount of aircraft. While this may not sit well with everybody, I believe we must reach a compromise somewhere. These "lines in the sand" don't accomplish anything.

FWIW, I think the multi-tier system is a good solution, and I also wouldn't object to a speed limiter provided it worked reliably. I would, however, like to see the weight limit raised for twins & such.

If you haven't contacted your VP about this issue now is the time to do it. At least let them know that you have a voice and deserve to be heard.

Respectfully,
Bob

"If it ain't broke, don't try to fix it" and it's corollary, "Perfect is the enemy of Good" Redux

Since 1999, when I got the first plane capable of 200+ MPH, having flown hundreds of jet flights myself since then(wish I was a better pilot after all those flights), and having attended many jet meets in the interim, I have never seen one instance of a CD, Safety Officer, DB, or any member of the EC, ground or severely criticize anyone for exceeding the 200 MPH limit......Why??....most guys aren't really going over 200, and those that occasionally APPEAR to do the 200+ low pass, are some of the most skilled pilots in the hobby......and even for those few, and I mean few, I have never seen a speed gun in the hands of the CD.....so we were never absolutely sure they were going over 200 MPH in the first place.....

CD's spend more of their enforcement time scrutinizing newbies and making sure that low passes were done a safe distance from the flight line and spectators, and that no one routinely busted the dead line on their upwind passes, etc....self-policing has been working, as noted by our clean safety record....

That was the Document 513 world until Oct. 31st.......

IMO, there were only 2 crucial issues that should have been presented for 513 implementation at the Nov. 1 meeting.....given the short time allocated to the TRC.....

1. Fuel load/Gross Take-Off weight for "Big Bird" turbine aircraft

2. Buddy Box approval for turbine training flights prior to turbine waiver test flight before a TCD

There was also a re-certification issue that probably needed some attention.....and a couple of other non-controversial housekeeping items like the availability of water fire-extinguishers.....

The first I heard of this screwing with the 0.9 T/W--200 MPH rule was after the blowup on Nov. 1 ....up to that point, and even for a few days after the Nov. 1st meeting, everything was CIA Top Secret, maybe not to the inner sanctum of the TRC and their homeboys, but at least to those of us up in the remote northlands of Wisconsin......just rumors about DB going ballistic over something.....

Like it or not, DB is the President of the 170,000 member AMA, with fiduciary responsibility to each and every member for 2004......forget, for a moment all this "democratic" babble...take some time to read the U.S. Constitution.....the AMA governance structure was not mentioned in my last reading.....

Believe it or not, all closely held corporations, for profit, or not-for-profit, are, for their own survival, sustained by a strongly pyramided governance, with the President/and or CEO having enormous power at the top....anyone doesn't believe that, check out the EAA/Tom/Paul Poberezny connection, or the NRA/Kayne Robinson/Wayne La Pierre connection, or your local hospital with it's 100 million/year budget, run by a pit-bull, autocratic CEO.....and if you read the fine print in their ByLaws, you will notice, across the board, that it is very difficult, often impossible to remove the incumbent autocrat at the top of the pyramid, without spending an enormous amount of time and money....including, in most large, hobby-related organizations, running for office, from the ground up........>>At last count, no VP was flying R/C jets, and only a few AVPs were active jetsters.....

Anybody interested in running for VP spots open in 2004 with the hope of unseating DB in the near future???....just remember, it is time consuming, and your fiducidary responsibility will not be exclusively to jetsters.....gonna have to spend time with the rubber band twisters, free-flighters, control-liners, indoor electrics, outdoor electrics, etc, etc....and the pay ain't all that great, I am told...the Board Meetings are in Muncie, not Cancun......baahhhhh! Definitely will cut into building, painting, and jet flying time.....and you really gotta love being a politico......i.e. talking to pissed off SIG noodleheads at all hours of the day and night.....

Anyone flying turbines for more than a day has known that DB and the EC have considered speed control a "Hot Button" for years......it is one of the ARBITRARY carrots that they feed the actuarial/legal bunnies when it comes time for insurance renewal each year......no more, no less....

It all begs the question.....Who decided to screw with the current 513 Speed Regs in the first place?? and Why?? Did anyone really expect to see an AMA/DB-endorsed speed free-for-all in the forseeable future....

When you take delivery of your Red Lambo Countach, the first thing you DON'T do is drive into the State Patrol Office and ask them to get rid of all those ARBITRARY 70 MPH speed limit signs in your neighborhood......especially when the Boss Trooper's home car is a rusty, six cylinder, 1968 Plymouth Duster and he has let everyone in his county know in no uncertain terms that 70 MPH means 70 MPH......if you gotta satisfy that Lambo speed monkey on your back, you go out into the hinterlands, where Officer Friendly ain't, and put the pedal to the metal.....and don't be naive enough to expect much sympathy and support from your fellow citizens, who may also be stuck driving old Dusters, if you do get careless and get busted......

Feb. 7-8, 2004 and March 31, 2004 are rapidly approaching.....Doubtful that the names on the offices at Muncie, occupied by the President and EC will change by then.....If all the TRC plans to offer DB and the EC is a pile of over a thousand RCU postings and emails, with most of them being repetitive ad hominem(ball-busting) attacks on the AMA leadership, and persistent pushing of the Speed Control "Hot Button", we might be in trouble.....even the coolest of heads can get vindictive.....BV, at SM 2003, realized that when he mentioned the "22lb thrust limit" that slipped out of DB's mouth....perhaps a bit of hyperbole on DB's part, but keeps me wanting to check my six...Matt thinks the Speed Limiter thing is a big mess.....agreed.....but if we don't have reasonably priced rates for Property Owners Liability policies on March 31, 2004, and are slapped with some Draconian new set of T/W rules, then we have a MESS that could take years to sort out..

Good post, Tom.

If I was a betting man, I would say that mandated speed limiters on some aircraft is going to happen. And then we will have to figure out which planes are affected...it is easy to say a Eurofighter is exempt, but how do you write a rule that is specific to aircraft designs? Not easy. T/W is easy to define, speed is easy to define, drag and speed potential is not.

The mess I was referring to specifically is the certification process of these new third party speed limiters. They know this up at the EC and the industry needs to do some creative thinking to come up with something that works. I have my ideas but I am going to hold off on them until I meet with some of the AMA heirarchy in about 10 days.

Matt, speed limiters are the only way to go. Think about it the .9 aircraft are the only airplanes not required to have them now. After a couple of years the technology throughout the industry will completely catch up and speed will then not be a issue at the underwriters table or the flight line. We should utilize technology to make this easier on us, other AMA members, and Dave Brown.

Lee,

Your statement above clearly indicates your lack of knowledge on speed limiters and is indicative of the thinking of DB as well. Speed will always be an issue, even if we mandate speed limiters for all jets (that is what I REALLY hope they don't do). First, if we say we are going to limit speed to 200 MPH, what speed are we talking about? Indicated airspeed, calibrated airspeed, true airspeed, or ground speed? If its true airspeed, there isn't enough technology available to measure that accurately for a model airplane. Look at the pains that full-scale aircraft designers go through to find an acceptable location for the pitot tube! Then, when they find the best spot, they STILL have to calibrate the airspeed indicator to account for the non-linear response of the system. Then the pilot has to account for differences in air density due to heat, humidity, and altitude. We don't have to be that accurate you say? Then what is the acceptable limit for the error? shouldn't that be accounted for in the regs? Oh, we'll also have to find an acceptable location for the static port, and tune the system so it doesn't manipulate the throttle in such a way that the engine flames out. If its ground speed we're interested in, how are we going to compensate for the inaccuracies of the GPS system caused by position error or the 1 sec. typical update rate? Finally, we have to worry about what happens to the system when the limiter fails. Is the AMA going to insist on a fail safe design? What should the safe-state be? Right now, one of the units on the market has been known to fail in the full throttle position. How safe is that? How safe is it to fail in the throttle closed position? Is a fatality or a fire caused by a jet that stalls on takeoff and crashes into the pits because the da*& speed limiter malfunctioned better than one that was caused by an jet going 200.5 MPH?

Let's put the onus on the pilot to fly the aircraft in a controlled manner with the speed corresponding to the capabilities of the aircraft, the pilot, and the situation (i.e., flyin with 2000 spectators, dry lake bed with nobody around, etc.), that is the only rule that is TRULY enforceable.

As a new turbine pilot, I have been watching this thread with interest (and concern) for quite a while now. Lots of good points and observations... and some attitudes that scare me. I really like this aspect of the hobby and want to enjoy it - in a safe way - for a long time to come. With minimal restrictions.

FWIW, I am a long-time AMA member and have been flying R/C for more than 30 years now. I don't agree with many things AMA has done, but I also realize that without the AMA, we have no voice, and we WILL get regulated or pushed out of the way. As it is, there are only three places I can safely fly my jets and large models within 120 miles of my home - and two of those are open to active/retired military only. Without the AMA, I doubt there is any organization that could help the modeling community to keep flying sites (and get insurance so we can continue to fly at them). Like many of you, I have a sizable amount of my disposable income tied up in my hobby.

I also fly large (40 lb, 40%) scale aerobatic models as well as 200 MPH (no BS) capable sailplanes and F5E models. Both can kill you - as can the typical .40 size trainer. But let's not kid ourselves, turbines present a much greater potential for damage (i.e. fire) and therefore a greater liability concern to the AMA's pool of insurers. If all I am required to do to maintain AMA's support is add a $160 airspeed sensor/speed limiter (a capability already built in to my P120's ECU) to my $7,000 jet, I am not going to complain too loudly.

Tom is 100% correct - whether we like it or not, changes ARE coming and the jet community needs to take a serious look at the public face we present to !QUOT!the other 98%!QUOT! (more like 99.958%). While not all turbine pilots have !QUOT!the attitude!QUOT!, some do, and it only takes one bad apple to spoil the bunch. ****ing about the AMA won't help (rather, it has the opposite effect), nor will whining about DB or your VP/AVP's. We need to provide positive, constructive feedback with solutions that we can live with - rather then having restrictions we DON'T like forced down our throats.

And since I am venting, might as well keep going. Here's a few of my observations as a new jet jockey. FWIW, I am sure I will eventually get as jaded as you more experienced turbine pilots and forget all this, but I think these are worth noting....

1. 200 MPH isn't as fast as you think...according to my JetCat GSU, I have hit 197/199 MPH without trying on several occasions. This is with a tired HotSpot and 123K RPM P120. Big models don't appear to be going as fast as they really are.

2. 200 MPH is not comfortable or much fun to maintain for any length of time (and I flew F1 and Q500 for a few years). It's one thing to maintain 200+ when racing another plane in a limited area but not when you are flying for fun. For me, anyway - and I suspect, for the majority of turbine pilots.

3. The waiver process is a pain in the ass, but necessary - I have no complaints. In fact, I think it should probably go a couple steps further and require more in the way of ground school/written testing, on aircraft structures, safe control installation, in-flight emergency procedures, maintenance procedures, etc..

4. We NEED to allow buddy box training during the transition phase. Taking off and flying a turbine is no big deal, but landing is another matter. I have maybe 10 solo flights now and I am still coming to grips with landing approaches and consistent landings on a spot (damn turbine lag!). Fortunately I have been able to hang with and get advice from some very experienced pilots - but what about the guy out in the boonies? A waiver does nothing to prepare you for the actual first flight experience.

5. I have an ego, like everyone else...and while I'd like to think I'm ready for a 55 lb. twin F-4, NO WAY am I safely capable of operating it in all regimes without some more turbine flight time, working up to it. BV's proposed tiered system, based on demonstrated experience (or something like it), makes a lot of sense to me. As it likely would to our insurers.

So, let's drop the attitude and work on proposing some reasonable solutions for the AMA to consider. I am open to discussing this with anyone, please drop me a line. I'll also be sure to attend the (rumored) open discussion on turbine regulations and safety with DB and the EC at the upcoming AMA convention in January.

Flame suit on - back to work I go.

I finally received my new issue of MAN today, and read DB's article. I am gong to ramble a bit, so please stay with me on this. His article brings several interesting points into very clear view.

Besides back-door trashing the creditability of a lot of pretty good folks, it's pretty hard to read anything into the article except the obvious. I believe it's now only a question of how soon, and how much (or little) will he actually do. And, for those of you out there who don't want to believe it, it will be his call.

As for the 2%, I guess he is referring to all of the !QUOT!high risk!QUOT! segments of R/C. With the jet community (700 +/-) that is less than 1/2%, leaving about 1.5% for everything else. I don't think that adds up. There certainly must be 3k to 5k giants (IMAA types) ships out there. Regardless, the !QUOT!high risk!QUOT! numbers are very low.

DB told me last November that he expected at least a 50% premium increase, and that was regardless of any specific activity, jets or no jets. So we should not be picked on for that, should we??? Based on personal experience, I told him that I felt that would be a bargain in today's market. We are all paying the piper for several years of very low rates. Remember that DB is the insurance commit, and the insurance only hears what DB tells them. Garbage-in, Garbage-out!!!!

Something else that struck me in DB's article was a sense that all of this new technology, larger airplanes, bigger engines in all models happened overnight. DB talked about being part of the EC for 30+years, and leading the organization for most of the past 10, where has he been??? We all remember the giant scale racing that was a big boom started in the early 90's. The giant scale (IMAA) planes of 10years ago were 85 - 90 inch wingspan then. I had a Godfrey Ultimate with a Sachs 4.2 on glow swinging a 24/12 APC prop 10 years ago. And, turbine jets were starting to show up in the early 90's. So I ask again, Where has the AMA been? Obviously they have been so far behind the curve that they have about fallen off.

As the leader of an organizations of 170,000 it seems that DB would have made an effort to be in very close touch with all of these advances in technology. Not only has he not been in touch, he has not seen to it that anyone from the AMA has been in touch. Now they are trying to administer rules and regulations that many in the leadership know little about, and it's perfectly understandable that those who don't know can't do.

As for the rather despicable way he is attempting to turn the balance of the R/C - AMA community against turbine powered anything, it simply adds to a lack of credibility for BD. It would have been really great if he had revealed some of the pitfalls and problems, and then admitted that we (the AMA and DB) have really screwed up, but we are gong to correct it. What a refreshing take that would have been. I don't believe anyone would fault him for admitting the obvious, instead of trying to blame all the problems on a few guys who do a pretty good job.

Thanks for listening in.

AMEN!!!

Guys, you sure sound elitest to me even though most of you claim not to be. Take note of my earlier post! How many of you are involved with your club? Are you an officer? Do you work with other non jet guys? Get your club members behind you. Look me up at www.wdarc.org You'll see we like jets and Giant Scale. Many were leary of both prior to my taking office 3 years ago.

We need to all work together and quit whining like babies! If it is a speed limiter so what? I have a Euro Fighter with a P120 and we all know that won't do 200mph even off a cliff. If it is required, I'll add it to the plane. I think we need to pick our battles so please pull your heads out!

Another post mentioned risk managment. I am going to call Dave Brown personally and ask him if he has a detailed safety checklist that most of us live by with Turbines. Perhaps an Underwriter will be more relaxed if they know the precautions we all take.

john,

you hit on the same things I did. the 2% is those pushing the envelope. the turbine references are those that are still stinging him. my biggest problem is not that he wants to look things over, but the bashing he laid in his column. even if he were to apologize in the same forum, the damage is done.

Glenn,

I hear ya however, in my opinion, there's more to the speed limiter issue than just installing one......

#1) There are only two manufacturer approved speed limiters on the market. (JetCat and BMT)

#2) There are not ANY other manufacturer approved speed limiters on the market.

#3) The only other speed limiter on the market has been known to fail or not work properly.

#4) Speed limiters only work up to a limit in slowing down a really clean plane...You can still break 200 MPH AT IDLE under the right circumstances.

If an aftermarket speed limiter is approved, who will do the testing to see if it is compatable with ALL of the other turbines on the market and works satisfactory??? What, if any, affects will be on your turbine warranty if forced to use an aftermarket speed limiter not approved by the manufacturer???

Until we overcome the above four problems, there are serious issues with mandating speed limiters on ANY turbine model.

Kevin
