I dont like the physics of stall in FMS, the plane floats a lot, the ailerons feels blocked and the engine does not produce the normal rotation to the left; also the planes are more likely to harrier than hover and it is almost imposible to torque roll them... Iīm using the Ripmax RC Sim and fms, FMS works better for me to practice pattern maneuvers and the other sim for 3D.
Start practicing hover looking the canopy, then the belly and then you are ready to torque roll. Remember that when you are looking the belly the rudder goes to the opposite (as a rule, to the lower wingtip).
God bless RC SIMīs
