On your backoff, did you actually back off 3 turns of the motor or the
winder handle ? Just curious

Rey asked on INAV:
... what torque you wound to and did you back off any turns to a lower
torque? How many turns remaining at end and torque at end of flight if
you recorded it?
I wound to 0.5 in-oz at 1712 turns, backed off 3 turns to 0.4 in-oz. On
landing, I forgot count the number of turns remaining. A few minutes
later, when I realized that I forgot to count it, I estimated that there
were 70 turns remaining.
It was the first flight of the motor. I've never flown well on the first
wind and always had doubts on the rubber's output on the first wind.
Consultation with Brett helped to dispel those doubts.

Good question. In addition to the list below, I would add skewing the
wing. I.E. right wing panel ahead of left wing panel to induce a left
turn.
I have observed that many (some, a few) indoor planes fly to the right
when the prop stops providing positive thrust. It would seem to me that
trimming the plane to fly straight or to the left when this happens would
be more efficient.
Is it possible to rank the effectiveness of each method of inducing a
turn at full thrust/torque & again at low thrust/torque?
At least superficially, stab tilt would seem to me to be efficient. What
are the inefficiencies or down side to this method?

Which reminds me: How do we set left thrust, stab tilt, left rudder so
that the forces are balanced (which I assume would be the most efficient
way to turn) ?
