We currently have 2 Freedom Flight monoplanes that work decent under the right torque (torque of 0.25 oz gets around 1:30 in 24 ft), however with higher torque we experience a lot of the problems described earlier in the forum including power stalling and diving into the ground. I read about the wing wash-in and I know there is a shim included in the kit to help with that, but I feel like I'm not alone when I say I have no idea how to use and connect it to the plane. The instructions on that part are a little unclear and many of the teams I've talked to don't really understand it as well, so have omitted it. However, I think it is time to figure out how to use the shim as our state is in 90 ft and our planes need to be able to handle the torque. If anyone has a visual on how to use the shim it would be greatly appreciated, or an alternate way to fix the high torque problem.
Also, I was wondering what our first change should be when trimming (incidence or cg?). I usually leave the incidence the same and just move the wings backwards or forwards to adjust the cg, however I don't know in what situation you would change each one to optimize the trim. Speaking of which, how do you know when the trim is optimized (whats should the climb, cruise, and descent look/time like?). Sorry for so many questions, many of which have probably already been answered, but I would really appreciate the help!
Send details of all current trim settings and flight character: CG location (measured from the wing trailing edge TE), wing incidence (difference between wing TE to fuselage top edge measurement and wing LE to fuselage top edge, rudder offset measurement for both directions, any twist in the wing (eyeball it and estimate, ex. 1-2 mm left wing TE lower than LE), rubber weight and length (measure before winding for the first time; or if wound already, indicate how many times),number of turns on rubber, number of backoff turns, maximum torque before backoff, flight circle size, nature of power stall and drop (is it rolling to the left when diving or stalling straight ahead and then diving), propeller type and blade pitch angle.
With this information, we can give specific help.
