I have read much about the MD-8X series and what was mentioned again and again by people claiming to be pilots of this plane is that during the early moments of climbout (high AOA), and particularly at high TOW, the plane is very sensitive to aileron input.....and that rudder should be used instead to keep wings level until airspeed increases. Does that sound anywhere near correct?
Rudder is the primary control to keep the aircraft from yawing and it is yaw that is the primary problem in an engine failure. You can actually perform a V1 cut and NEVER use ailerons and keep the wings level and the nose going straight.
IF however, the pilot begins using lots of aileron, it can and often does compound the control challenge.
You have to make yourself make the correct input and not relax and reduce that input. Doing so begins a dance that can result in losing control. To get an appreciation for the control surfaces, look at the rudder. It is the largest control surface on the airplane and with proper rudder input, a V1 and V2 failure can be dealt with.
