my guess is how its set up Dale. my pattern planes are slightly nose heavy...my 3d planes tail heavy. either way...it takes me 5-10 flights on a new plane to 'bond' with it. i will set up my matrix tail heavy and use lower rates for pattern flying..then see what it does for 3d. i kinda think that a dual purpose plane quite doesnt cut it...but we'll see down the road when i get it together and do some flying...
