- I had to shorten the wingpins by 1/8" to make the reed switches work correct. I didn't have to enlarge the hole in the armrest. -Completed most of the wiring. Missing some washers for the headset jacks. -Wiring still needs to be bundled. -Had to make an extra 5/8" hole left from the forward bushing because the aft hole will not be useable due too the lentgh of the mode S-transponder. -I had to grind the small bushing in the tailcone for the static line to fit. -Working in the back works great with the fuselage on its side.
