I have a Thunder Tiger E-Hawk 1400 with a Brushless motor that is very sensitive to throttle inputs. It goes from flat flight a 0% to near vertical at 100%throttle. I have calmed this in other gliders by mixing 12%( % variable) down elevator to throttle steps 2-5. With the E-Hawk I installed two servos for the rudder/elevator (channel 2/4) function and turned on V-tail (Aero-not in Glider mode). Ailerons are in channel 1 and ESC in channel 3. When I mixed channel 3 master to channel 2 slave only one halve of the elevators moves. Any help would be greatly appreciated!!!
