Hi Vladimir.
I flew with it yesterday in Rantoul. The conditions were in the mid-70's, with fairly high humidity.
These are all subjective.
At the NATS, I flew my Coconut scale model Taylorcraft with a relatively crappy batch of TSS ('04) with six strands. Yesterday I bumped it up to 8 strands of June 2016 with a longer motor and had trouble keeping it out of the ceiling. It torques up nice. If I stay with this much rubber, I will need to make the motor longer and braid it, also increase the prop pitch.
LPP. I used only one prop and this has issues when launched at higher torques as the flair is quite uneven now. I ended up with an 18 to 18.5" loop of 0.101" giving me fairly consistent times of just under ten minutes. Several times it bunched up in such a way that it gave me an unwanted torque burner - those times were significantly lower. Again, rubber torques up quite high and my prop did not like launching at more than 0.6 in-oz of torque. It would already wobble a lot at that, but higher than that it looked like it was drunk or having a seizure or doing some sort of weird dance. Had I spent a bit more time with it, I know I could have gotten it to break 11 minutes.
F1D - One good hard wind, backed off to a reasonable launch torque of about 0.4 in-oz. Noticed as I was loading it that it seemed to have more pull than 5/99 or 3/02, and impression was more torque with less max winds. Fuselage folded right past the front brace, in front of the wing post. Was able to cut the motor and save everything but the motor stick. At that point I put it back away.
Will do some real testing soon.
Regards.
