I'm not sure anything under 27.5 pounds would be possible with a DA and cans. Mine was BARE when I weighed it (no spinner, pilot, or wheelpants, no matchboxes, no dual rx, and single rudder servo) and it was around 24-3/4 pounds, and that's with a BME and stock muffs. I dressed it up a bit with a spinner and the pants and now it's a little over 25-1/4 pounds. So my exact setup but with a DA and cannisters would have been closer to 28 pounds. I definitely feel for you! My Yak barely pulls out of a hover at our elevation (well, my 6800 feet - chatfield pull-out was pretty good.), so yours must be a glorified trainer!
Will you be at the Big Bird fly-in in August?

Out of the two I was looking at, the QQ and the Aeroworks Extra...they are all coming in about the same weight. The aeroworks, may be a little heavier with a few of them coming in at 29 pounds. I'll be fine with a 27-28 pound plane and I'm sure it will fly fine at my elevation.

Sure, you can get the weight down by going with single batteries, no cans, single servo on rudder and ailerons, no matchboxes, etc. - but I like the peace of mind 2 batteries and things like that bring to the table.

Randy Racer,

Mine is a Gen I plane that was purchased in Dec '05. Happy to hear
yours is going together so well. I am sure QQ and Wayne
are listening to their customers. I should have waited, perhaps mine
would have been a better experience.

Bodywerks,

I would say it much better than a glorified trainer, but could MOST
certainly use an improved thrust to weight ratio. My DA is turning
6000 rpm on a 27x10 Bolly at 4700' and I am hoping it will pickup
2-300rpm once its broken in. I plan to remove the smoke sytem
and that will save almost a pound. I do plan to attend the Big Bird
event, but most likely as a spectator.

I just need to figure out what's next and avoid any further poor
choices, perhaps, I will build a Carden or Dalton plane.

When you finish, let us know how much it weighs and with what equipment you outfit it.

bodywerks

My Feedback: (4)

He already did. It was 28.75 pounds.
Don, you could go to a 27X10 Mezj and gain a couple hundred RPM off the bat. Will your plane even hover, though?? A plane without enough power to hover is a glorified trainer in my eyes.

Bodywerks,
Yes it will, it seems alittle over half throttle w/o any throttle curve.
I have yet to master the torque-roll but was able to get about 270 deg
rotation on one Monday. All at this throttle setting... If I pull a wall and carry the upline 50 feet or so and throttle back till the climb stops I can
then nail the throttle and it will pull upwards again building speed and
climbing till you pull back on the throttle.

But like I stated earlier, more thrust to weight would be nice.....

The Mejlic prop is a good idea, do you know anything about the Vess
props? I seen comments both ways....

I am interested in them, but haven't run one. What I do know is that you have to run an "A" serires up here if anything. Guys at sealevel are saying the "B" series is almost to much load and the "C" series are almost useless unless you are running full-length tuned pipes or a ZDZ120 ore evolution 116.

Don, contact Robert Vess. He can make some recommendations and give you some direction on his props. We are seeing some awesome performance improvements here near sea level and Robert has been working with some folks at high elevations too. On top of it all, he's an every day modeler and all around great guy that is interested in bringing a better prop to us all ... including himself.

No advertisement ... just giving you my $0.02.

jsnipes,
Thanks for the tip, I am always looking for a way to get more performance from
my setups. I found his web at http://www.vessaero.com/body_index.html
and spent sometime there.

Appreciate the help,

Rick,
Search my posts in this same thread around December-January.
I had exactly the same problem that you are experiencing.
If you search the forum for 3W QQ106 issues, you'll find many more people with almost identical comments in all sorts of airframes.
Yes, there are many of theses engines that are working great, however, there are too many engines with this - or very similar - problems.
I finally changed to a DA100 (identical mounting holes, just needed to adjust for a 3/4" shorter engine - and a touch lighter).
Same cowl, same location, same everything - runs perfect.
Funny that there are many others like you and me, many many posts, and 3W continues to insist that "it's airflow problems" or "keep leaning the low end".
I have competed in a few IMAC tournaments and the word with 3W is: "make sure you get an old ignition module, the new ones are !&%^!&$^$@"
I know it does not help but you are not alone.

Happy flying
George

I have been flying with the 27C and I like it better than the NX 28X10 I was using.
DA 100, standard mufflers at sea level, 27.5 lbs
Horizontal flight: I find that the plane speed is esier to maintain constant at slightly different throttle settings. (I am not fighting the speed stick constantly, the speed is steadier)
Verticals: It pulls slow and steady, unlimited. Easier to maintain constant speed.
I like it!
Just my $.02 also
I am not doing any 3D, just IMAC.
May be for 3D I would like a "little less prop, a little faster response" a would probably try the B (or even the A)
Happy flying
George

Gbrod,

I am flying the "B" and it is a good balance of 3D and precision. I originally had a Mez 27x10 and I like the Vess 27B better. I have better pull out of a hover, its more contant speed as you mentioned, and it's quieter. There is a lot of thrust at low rpm so you have a lot of control in a hover or TR. I've been thinking about trying an "A" just to see the difference, eventhough I'm real happy with the B for my style of flying.

hey guys i've almost got my Gen II ready to go and i have a couple quistions. how much space do you have between the cowl and the prop? i am getting 5/8" with the stock block and a DA 100 i feel it should be more like 1.25"? also how much and what are you cutting out of the cowl for air flow? i don't want to cut the bottom of the pipe tunnel out if i don't have to.

I would try to do an inch at least to get the most effective thrust. Mine is around 1.25", though, mostly for CG purposes.

well i got to maiden my new love yesterday. got 4 flights and this is a awsome airplane. it will need a few adjustments but for the first flights it was rock solid at everything i threw at it, flat spins, blenders, walls, waterfalls, harriers, houvers, knife edge was good but needs some mix. with a little work this plane will do it all with style.

it came in at 27.5lb with

DA 100 stock pipes
Vess 27B prop
JR 8611A's all around
SWB rudder tray
2 4800 Fromeco's
1 2400 Fromeco
3 regs
3 Fromeco Badger switches
and Ritchard my helmet head

it's so much better than the AM35% yak i just lost. i thought it was a good flying plane just to heavy and it hurt to see it go down but flying the QQ 102 Yak has made me feel alot better.

Interesting, the different spacers - using information from this thread, I did mine with a total of 1.5" of spacer - the result was that my RX batteries are located inches behind the tube, on the flat balsa flooring - a very convenient spot. My engine battery is on the box with the ignition module. This is the only plane I've ever had (35 years doing this) for which I have never changed the CG - I started with what was suggested, and have found that to be perfect (I am really picky about CG, so this has amazed me - about 150 flights to date, and 0 concerns with CG).

I'm finding the weights to be interesting too - mine is a Gen I, but with wheel pants, and two RX batteries, and standard DA mufflers, it came in at just under 25 pounds. Consistent with QQ's 26 pound plane with the cans. I don't have any power management boxes, etc. - just two HD switches, and two batteries.

randy racer

My Feedback: (3)

it would be very easy to get mine down to 26lbs by using 1 2400 pack saving 8.1 oz, lighter wheels around 4 to 5 oz, 2 switches at 1.5 oz, and leaving the SWB rudder tray off with the pully system not sure of the weight on that but alot heavyer than bolting servos into the supplied ply and using a match box. i love the way the SWB tray works and the extra safty it offers also like running 2 batts on reciever( 2 2400's would save 6.6 oz over the 2 4800's i'm using but i had them all ready. still a great flying plane and i may do some changes at a later date.

I really think it's a matter of getting lucky when it comes to kit weight in order to get the finished weight down. Knowing that there are these Yaks out there with DA's weighing the same as my plane with a BME kinda upsets me. I got a new plane in the hangar now - maybe I was holding a winning "low weight" lottery ticket, who knows?

randy racer

My Feedback: (3)

bodywerks i hope it works out for you. my AM yak came in very heavy at a little over 32lbs and everyone said theres came in at 29 and that hurt my feelings. it still flew well but the hardware was not so good and thats what caused it to go in. aileron linkage poped off and caused flutter and took it out but now i have a QQ 102 and it a wonderfull world.

My Feedback: (4)

Me, too. So far, the power of the BME is not impressing me. There is a guy I went flying with today that has a DA in a plane that is 2 pounds heavier than mine and his pullout of a hover is way better than mine, and he's on stock mufflers and spinning a 28X10 mejz prop 300-400 RPM faster than I am spinning a 27X10 mejz. Of course, his engine is doen breaking in and I am still on lawnboy and running a little rich, I think - at least I hope so! Otherwise, byebye BME!

Troybuilt doesn't seem to think much of the power of the BME. They prefer the DA. Breakin does have a lot to do with it though. I'm around 400-600 ft here (hilly country) - the DA-100 should pull the heck out of this plane for me.
