RE: intro to turbines
 
I just purchased my first turbine, a used but very well maintained RAM 750. I was set on getting a Boomerang Elan, then I seen your post (picture of the Turbinator). What thrust are you using in this jet? Would it be a better start over the Elan? Just asking your opinion. Thanks.

Thanks for the reply smitty....I'm actually in el paso, and I haven't seen a lot of people fly turbines out here in el paso. Yet alone flying at all. That's a great suggestion and I would have done that but, the jet guys just don't seem to be around here.
I fly in El Paso. There is a new very nice field in Northeast going out McCombs, then turning right on Stan Roberts at the 4-way stop sign. Also another off of Montana street on the East Side as well as another new one on the East Side (Horizon City's new field) and there are flyers at the Sod Farm on the West Side. The Northeast Club (El Paso Radio Controllers) has been around over 40 years with around 80 members...

I have been to the field out to the n.e. but every time I have been there there has only been 2 or 3 people flying. Maybe its the wind that keeps people away. Haven't been to the horizon field yet but I will eventually.
Thanks prop washer.

The falcon 120 require quite a bit of mods and the cheapest kingtech is K80 which I am not sure if you can get anymore, you may be stuck with a K100 (I was told K80 being discontinued not sure if that is still true).

The K100 is way too much power for the falcon 120 without major modifications. If you got the $$$, the tornado is a falcon 120 done up right. YOu can put fixed gear on that too.

I would hate to you see get frusterated and lose a new turbine to a questionable airframe.

By the the time you do the mods to the falcon 120 cost wise you would be a tornado pretty close. I went with the F-86D great trainer but lots of mods again. I woudl of done tornado but transport is hell. YOu have to remove the booms and wings and this is a point for error, getting it hooked up right everytime. They take a lot of wear and tear being taken a apart like that.

If you can keep it together in 1 piece you will be much better off.

If I could my first turbine over again I would get a turbinator or a jet mach. They fly so good and are so easy to fly. No bad characteristics, othyer than FUGLY.
Thanks for that info sir, I will consider that. Not trying to do any mods on an airframe either, when I can just buy something that's built for a turbine. Thanks again sir.

Hey Sgt,
Are you a crew chief on Chinooks?

Henry

I was at my previous unit and rank, now i train, supervise and mentor my soldiers, oh and discipline them when they get out of line. I'm no longer a flyer but a wrencher. I will post a nice pic of me flying.

Kingtech was pointed out to me and I'm going to go with it.. as far as airframe...for my first I want something with simplicity. Something to get the basics down...not interested in retracts and all the bells and whistles. So I'm thinking of getting a falcon 120 and keep the fixed gear on it. Then after some time flying that step up to something more sleek and spotty, maybe even a scale jet.

The Falcon 120 is a great jet, and they are dirt cheap. I know a lot of guys here will put them down as not being a real jet... but with a few simple mod's... and not trying to make them fly at 180 mph... you will have a model that will get you though the turbine learning curve. Besides... if you crunch one... it's only $150 for a new air frame.


I was in the same boat as you 2 years ago. Wanted an inexpensive trainer, without the complications of retracts. So... My first attempt at flying my Falcon was to use the stock fixed gear. IT SUCKS !!!!!! It bent before we ever got off the ground. So... I made a nice spring loaded nose gear, and changed the main gear over to an aluminum set. By doing that... it supports the engine and wing mounts better, and it's MUCH easier to put together and transport since the fuse is on it's own gear.

If you get one, an want more info... just give me a yell. ;)

Thanks for the info, its a toss up. But glad there's plenty of guys with opinions and experience here to guide me along my intro to turbines.

Here is a good fix gear jet trainer call the JETCAP 242, Flys as good as the boomerang :) Only mod was to change the tail wheel to Aluminum [:@]:eek:

Wooowww.... Ok, now thats different. And badass. I. Bet its cheaper then buying a turboprop. Nice mod dude.

Hey Sgt (I was a Capt) If you have access to a Ipad and want to get excited about turbines download the App for RC Jets international online magazine for 99 cents and then for your free introductory offer download this months turbine special. :)
I will have to get me a subscription to it and get the mags sent to afghan land while I'm over, and hell if anyone has any magazines they want to send over that are older let me know I will hook you up with the mailing address when I get over there.

Thanks sir for the info.

Hes a NCO in the military, he was just showing courtesy, people have lost perspective on the fact that the internet adds a very big (lost in translation) factor, plus some people are raised to say sir to a stranger in our country. The problem with reading everything is 10 people can read the same thing and end up with 10 different opinions, probably the biggest cause of forum fights today.

Jetster81, I would have said the same thing about your comment. [:-] From what you typed you either were saying it looks like you got the right idea or just being a ***** trying to start something. Someone that wasn't trying to be a ***** would have cleared things up if their comment was taken the wrong way.
I found some of his comments condescending and the 'sir's' to be sarcastic which offended me.

Yeah that guy annoyed me , but I blocked him, but what sucks is if he posts here and someone quotes him I can see his post. Jester is just making excuses for being a bag, who gets offended by someone else calling someone else sir.?? Please go irritate someone else SIR.

I think you are looking into things way too much. Let's all just get along. I read the thread and no where did I get the impression that SGT was being rude or condescending. Let's just go back to doing what we all love. Talk about R/C! [8D]
Yes sir let's do it. R/c!!!!!!

I've also recently joined the jet crowd and am reading to prepare myself for a great 2013 flying season!

Consider a "used" jet that has been flown by a reputable jet modeler. Often you can find jet trainers for 60-70% of their original cost, for sale here on RCU.

A used jet will allow you to see one assembled that worked for the guy who flew it...always good to check things over and really learn about these jets before flying them.

Read up on "jet specific" hardware in your spare time.

http://www.dreamworksrc.com/catalog/index.php

http://www.sincityjets.com/

Also, jet specific forum...could be active, just need new guys like us sparking the fire a bit:

http://www.rcjetaddiction.com/

Read the forum posts on the Kingtech turbines if you're determined to use one of them, there are a lot of informative posts out there. Service seems to be good and accessible.

Safety: You'll need to purchase a CO2 or Halon fire extinguisher, a jet fuel container/pump system (hand crank is fine).

Thanks tiger for that advice and info.

Check out the official Jet Pilot's Organization (JPO). They are an advocate for all RC models and have worked with AMA and the FAA to secure our priviledge to fly RC aircraft without the restrictions of Small Unmanned Aircraft Systems (SUAS).

I joined for 2013, so I'm not sure if you have to be a member or if they are free, but in the left side bar, mouse over "Members" then click on "Contrails" for a TON of informative turbine articles. There's also a "Knowledge Bank" on there and some other good reading like "Saftey" and "Insurance" considerations. I found it all very informative...I'm not involved in the "politics" of jet flying yet, but I'm sure some will poo-poo the organization...don't listen to them, use it for the info right now and the chips will fall where they may down the road.

www.jetpilots.org


Other turbine links I've saved...

I'm getting these videos to watch them while I'm down for the Winter. Ali seems to be a pretty accomplished jet turbine pilot and successful with his set ups.

They are made for new turbine pilots and look like a great resource. These could make a GREAT addition to a "club library." I'm sure watching them once or twice will give you all the info you need, but it couldn't hurt to share them with other turbine pilots you meet down the road or at a club meeting for something different and to educate the club members where you'll be flying so they all understand the safety and discipline of a jet turbine modeler.


Ali and Jet Pilot Magazine has produced a couple of RC Jet instruction videos as well.

http://www.sksvideo.com/dbID/242.html;

http://www.sksvideo.com/dbID/304.html;

Maybe cheaper here as a set...check shipping costs:

And, believe it or not, YouTube has some informative jet turbine videos.

Jet Central ECU start up (all turbines go through the same stages of starting, but might have different ECU setups):

Seals for making things like fod screens from sink drains found at hardware stores:

RE: intro to turbines
 
hello there...there are many great jets out there to start with ...depending on your skill level most people start with a boomerang..i find this to be the best...light wieght big wing and floats well off power...i would rcomend one of the newer turbines with fast throttle response....jetcat makes many wonderful engines...a shok jet is fine but you will get very bored quick with that model...you want to get something with retracts so you can get the real jet feel...stay away from warbird jets and anything heavy at first..they make great 3 and 4th jets...take your time and get a good intructor...dont hurry yourself...and have fun....please pm me if you need any help with anything...have a safe trip......pat

Sgt Shay 12-20-2012 12:54 PM

RE: intro to turbines
 
Thanks pat for the help. I appreciate it. It's good to here several people and their advice and tips. It could come to a point where I would just rather but a scale jet, maybe because of a good deal, and if someone says buy it but don't fly it first, rather just fly something that's more trainer like. Bottom line is I appreciate everyone's advice, and tips and experience. Putting this amount of money and time into a plane isn't something I want to crash my first time flying a turbine. Thanks guys, any and all words of wisdom is welcome and appreciated

Links to jet ARFs....

While there are many different jet "ARFs" available today like the Boomerang series, etc. there is one ARF that stands out as revolutionary. Modellbau Tornado V3. Make sure to look at version three, it has all the "upgrades" and is ready to go.

http://www.modellbauusa.com/Tornado.html

I don't have one of these yet, but if you're looking to start from scratch, with your first jet, this looks to be the way to go. Modellbau has capitalized on the advanced technology of the most recent 3D ARFs by using carbon rods infused in the balsa wings and tail booms. The composite fuselage looks to be of good quality.

Check out build threads here on RCU for more info.

Paired with a 100 sized turbine this combo looks to be a jet that will grow with your abilities...can fly fast, lands slow...reinforced from the factory and designed for a turbine from the start...but priced very reasonably.

Dreamworks markets immaculate trailing link landing gear with integrated brakes...pricey, but will probably last forever:

http://dreamworksrc.com/catalog/mode...bo-p-2533.html

Depending on if you have servos, a receiver and a 2000mah (minimum) receiver battery laying around that is in good condition, you might be able to get this jet in the air for around $3000... A new turbine or one with a lifetime warranty is highly recommended, as the cost of refurbishing an older one that's been sitting around is a risk you take with used ones that have been sitting (bearings, glow plugs, etc.).

I've learned that a solid set up to begin with will save you money in the long run! There are lots of choices out there, this is the one that keeps coming up as a balance between a pusher conversion from Nitro Models and a real-no-kidding-turbine model with a decent price tag. You can always pay more! :)

TTRotary 12-27-2012 04:23 PM

RE: intro to turbines
 
Great thread. Following with interest as I'm also considering getting into the jets. As far as airframes, what about one of the Deltas like the Rafale or the CARF Eurofight sport jet? These seem like they would be easier to land due to the delta wing and relatively simple to build due to only 3 control surfaces with rudder.

Sgt Shay - I don't know how simple the LG can get. You will need brakes at a minimum. May as well go for retracts at that point.

Sgt , An event you will want to go to is called Kentucky Jets it is a must see event ! held in July and is the best of the best in my humble opinion. Also there is an outfit called Dreamworks ran by Linda and Todd those folks will take care of you and all your Jet needs for sure, check them out. Stay safe over there , hopefully we will see you at some jet rallys in the future !
