you may not believe it...but all Phoenix Model Planes are tail heavy......but when flying, the wing incidence brings the plane out level in flight. One model, the Dolphin is tail heavy...not by much, but in flight I have to dial in lots of up elevator. This month, I'm planning on changing the wing incidence by about 1/4 inch at a time and see how she flies. I tried tilting the engine upwards last month....but that didn't help. I really like these models and their workmanship has improved 200%. Hope you solve your engine/cowl problem.....you have some good advise to choose from. I use the front holes to bolt my engine and it works fine.

Cheers.
