John,

i think you talking about Torque-Rolls and hovering.
In Reflex there's a training set to learn that.
you have to take over one control after the other.
I mean first you start out with just the throttle and the rudder.
the rest is controlled by the computer. when you can manage
that, you take the elevators and or the rudder. and so on

real nice.
in any plane just shift the CG aft.

when i had the RealFlight G2 i also had a couple of planes
that torqued really easy. mainly the big ones.

i dont know about the old RealFlight.
you might wanna ask that in a realflight thread.
