I'm interested to know how to make a sleeve and use it. Your guidance
is appreciated.
On using a 24" motor on an LPP -- there seems to be additional
difficulties. I noticed the non-uniform bunching and subsequent
unwinding of the motor cause a rear shift in the CG, especially due to
rubber bunching near the tail hook. I read that you can do a
single-loop braid to mitigate some of this.
On winding such a long motor -- as I stretch wind it from about 100",
should I finish winding to its maximum torque when the motor is back to
its natural length of 24" or should I continue to wind it until the
motor is at 9"?
Thank you!

while the model is 75' up you can always (maybe) put up another flight.

never try to run a 24" motor on an LPP without sleeves. I sometimes use
sleeves in Cat 1.
