Gear Return Bumpers

Gear bumpers cushion the return of the gear after it flexes the bungees.  The originals are no longer available, but a much improved copy can be made from an axe handle protector.  One end of the axe handle protector is cut off (Photo 1).  A bandsaw does the job in a minute.

Axe handle protectors are available from Ace hardware stores for a few dollars.  (or ultimatetoolgroup.com)  Size HS-3 works great.  (Photo 2) You'll need two of them.

After cutting off one end of the handle protector, drill two holes about 1/8" diameter completely through.  Make the holes 2" apart and about 3/4" below the cut off end.  Push the bumper onto the fuselage frame in the gear return position and secure it with safety wire. (Photo 3)
