Rick,
Thats whats puzzling,when i roll inverted, the plane is almost perfect, i do have to hold a fraction of down elevator. But if i remember , i had to do that in all my birds when i go inverted.
Roll rate is perfect too, even slow rolls are outstanding.
When i hang it knife edge, its also perfect, half throtle she just hangs all the way across the flite line, if i go full throtle, she will knife edge loop. I also chop throtle from full, and she doesn't fall or climb, when i go back to full throtle. I have not checked it for 90 turn then pull pylon turn, i will try that tomorrow.
Thanks a lot for your input.........Paul
