My wiring is complete except for the PTT on the control stick. Yesterday, I put the left floor in and the pilots seat. I will definitely have to cut down the control stick. I plan a center panel angle that will house the mixture, throttle, prop etc. Does anyone have any good rules of thumb for how much to cut the stick down. It appears I should cut as much off the top as possible and then will also have to cut some off the bottom. I have Ray Allen stick grips.
Thanks,
