I have just started building mine and I want to know if anyone has flown one with a Brison 3.2 or BME 50 or equivalent ?

If so, what did you put where to get it to balance and how did you get the thrust washer 6.5" away from the firewall ?

Thanks,
Craig.

I have mine ready to test fly just as soon as the weather permits. I installed a "Taurus," 3.2 on mine and I mounted the Battery for the ignition, and the ignition unit on each side of the Firewall engine box. I mounted the throttle servo just behind the fuea tank, and every thing else as recomended by the mfg. My balance point is dead on the money with this installation. Now if the weather will just clear up.

Hurry up there Bob and get some weather---I am waiting to hear how your combo flys.---(really hope your top wing doesn't come off)

I'm going to call GP today and see what they say about it. In any event, I'm flying it tomorrow, come what may. The weather is suppose to be 85 and sunny. At least I couldn't ask for a better day to crash, if the wing should come apart. I'll post what Great Planes, has to say about me putting them on notice, or, if they are even aware of the wing separation problem.

I have always been a fan of big gas motors. However, I will tell you this. Ya better make some modifications to the wing mounts, if you want this model to stay together! Check the posts, guys are having seperation problems with the upper wing. I too, am having problems, and im running a bgx on that plane. The GP pitts is a super lite model, and too much power will no doubt shake it to pieces.

I sure feel sorry for you fellas that live up north. In Arizona its a rare day we can't fly

I just got off the phone from having a long talk with Greg, at Great Planes, warranty center. He, told me that he was not aware of any problems with the Pitts. He stated that he himself, had been flying his GP Pitts, 1/3rd scale, for almost a month, with a G-62, on it and had experienced absolutely no problems. I also read in this months "RC report," where Dick Pettit, and John Beech, ("Modelspport Magazine), witnessed Forrest Waller, fly his G-62 powered 1/3rd scale Pitts. He stated that the plane was assembled as per instructions, with only a few small changes. (none structually). Farthermore, Forrest, had only used two servos in the lower wings, and more importantly, he used no Flying Wires. Forrest used Robart hinges, (as did I) and a pull pull linkage on the rudder, with the servo being mounted under the cockpit. The engine thrust was measured at 25 lb. Thats a lot of power for such a light airplane. Here, I am going to quote what Dick said about his observation of the flight.
"After a 20' rollout Forrest pulled streight up verticle and headed for the high clouds! For the next ten minutes he did just about evey maneuver I've ever seen, and a few that looked like they were invented that day! The Pitts responded to each maneuver with good authority, showing absolutely no sign of structural weakness, even when subjected to some pretty violent maneuvers".
There is also another complete test review in the same magazine
that also gives rave reviews of the GP 1/3rd scale Pitts.

That sounds like a pretty good endorsement to me. But to top it off, and this is the best part, Greg, at Great Planes, Warranty Center, told me that "If you have a problemand the plane crashes, just send the part's , back and we will send you a new kit. Now I realize this is small compensation for all the hard work of building the kit, but what else could we expect them to do?

My advice to anyone thinking of purchasing this kit is to build it, fly it, and be willing to accept the risk you assume when flying any ARF. If you are afraid of the kit, just don't buy it.
Now, wish me luck, because, I'm going flying tomorrow, and if this kit has a weakness, beleive me, when I get through, it will show up.
