Hmmmmmmmmm, Mine required a shim under the top engine bearer, I took the bottom one out. See the pic's in the first part of this thread. It climbed at full throttle and when trimmed for that it would require lots of up for landing. After adding the shim it just flys like a normal front engine plane. They must all be built a little differently. Probably has a lot to do with lack of information in the instructions, ie... what angle does the front canard go in relation to the wing. I know mine could be moved in the slot provided about 5 degrees difference. Also the balance of the model, do you balance with full tank or empty tank for the postion shown? I balanced mine empty, some did it full and I think one even went with half a tank of fuel. After getting th first few flights over and trimming things out its a really neat little airplane. Maybe a little more comparison for the newbies so they can get it right the first time. I'm going to fill my tank and see where it balances with nose gear up and down and post it. I haven't checked it since i changed the motor to the OS LA 46. I know its about 5 oz's lighter than the OS46FX is, same prop and muffler though. I'll see where it is now because it's really flying great now.
