My brother and I have been flying the SU25T. Sometimes the plane flies like it should, other times it simply cannot be flown, or brought under control. This happens often enough that it detracts significantly from our enjoyment of trying to master the plane. We understand that if the plane is coming off auto pilot, it can be erratic due to amount trim dialed in by the AP. We also don't put the plane on AP unless it is flying level, hands off all controls. The problem we encounter can happen in flight after flying properly for a few minutes, but 90 percent of the time it occurs when you start a mission where the aircraft is in the air when the mission starts. The mission starts, and the plane is all over the sky. Sometimes after a struggle the aircraft can be brought under control, but usually it just crashes. We are careful to start the flight hands and feet off controls. The plane acts like very large amount of trim is dialed in at start up. Is there anyway to see how much trim might be dialed in when the flight starts? Should any trim be dialed in at start?
We have dead zones set in our controls of 10 or above. We use different sticks, throttle and rudder controls. Any thoughts on what we can do to stop this problem would be appreciated.
