Generally any trainer type of plane is set to climb at full throttle, so if you are trying to maintain a level flight at full throttle, especially with the limited capabilities of a pico/mini stick than you are fighting yourself...its meant to climb up , and fly around, maybe a loop or 2 but thats it, just something to give you real stick time...I learned on one in a schoolyard myself..you may need full throttle to do a loop or to head into the wind (10 mph) and it helps that they float in for a landing...you are just trying to fly full throttle on a half throttle plane is all.....Rog
