I'd like to share an idea I had. Fast, simple throttle, gear and flap levers with a strand of copper wire.
Hope you like ...
With your #80 drill bit reversed in the chuck (using the shank end), wrap a thin copper wire 3/4 around the bit. Bend the tail end to center the disk, and snip off extra
Flatten the loop with tweezers, and fill center with super glue (I add some talc for filler). Sand sides flat.
Install into pre drilled #80 holes in quadrant. If you drill right through, you can cement with crazy glue from the bottom, avoiding any excess cement on the throttle quadrant.
Hope you like this idea!
