Nice Foamy Pushrods

 RCG Maven balsa or carbon has some nice shots of foamy pushrods. Here's how he does it.

Start off two two pieces of music wire, one with a Z bend and one with an L bend. Attach the Z bent wire to CF rod with CA and shrink tube .

Round the other end of the CF rod with sandpaper and attach it to the L bent wire with silicone fuel tube.  Don't glue it, this allows you to adjust the pushrod.

Stick the L bent wire through a piece of rubber band. Attach the L bend to the servo horn, and stretch the rubber band around the music wire as shown.  Tighten the fuel tube with a zip tie if it's loose.

Stabilize the pushrod with a zip tie glued through the airplane body if there's flex when moving the control surfaces.

If you don't have any silicone tube handy you can zip tie a rubber band to the rod.  Here it is holding the L bend wire to a bamboo skewer pushrod.  BoC reports that it's tight enouch that he has to use needle nose pliers to adjust.  Notice hi popsicle stick control horn!
