Well until I find the rest of the switch, not much I can do. Somehow I misplaced the package it came in, pretty sure there are screws, and a backing plate(could be wrong and there was nothing else in the package). Today I fly, weather is perfect for flying, winds have died down from the 20MPH+ they have been the past 4 days. Going to maiden the Biper Cub, fly my P-51 a few more times, and get my trailer organized for the SIG Flyin this weekend.
