RE: Torque question
How much effort does it take to make the wing panels on this plane twist? If the airframe isn't tight, this problem will never go away without resorting to bandaid type compensations.
The torgue reaction after launch gets absorbed by the plane, the pilot corrects...then the plane should go where it's pointed until the next time that the plane has to absorb another hit of torque applied. Most of the time there is enough airspeed to help buffer the inflight torque reactions.
There is a constant low level of torque that causes planes to roll left faster than right.
This force is cancelled [I suppose] by a very minute amount of aileron trim.
