I think it is likely the rubber. In a subsequent wind, I believe 1750 or more would be possible at 0.5 in-oz.
5% less turns at the same torque would still be excellent rubber.
Thanks for that, Kang. The rubber I have can get close to that torque, but at about 5% fewer turns. Either my winding method or 5/99 vs my unk TanII or both.

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.
