Filling in a bit more of what I have learned about micro pushrods.
- For small flyers, the reference standard seems to be the Du-Bro Micro Pushrod System #852 (30" x .032"):
New Du-Bro Micro Pushrod System. (2) 30"x.032 pushrods, (2) 30" pushrod housings and (2) micro E/Z Links and (2 Mini E/Z Connectors. Great for indoor and park flyers! 2/pkg.
- The EZ links are: Mini E/Z Connector (Cat. No. 845)
- Hobbyking links come in 1.5mm and 2mm.
- The EzFly kit comes with 1.5mm carbon rod, 4 wire z-bends, and heatshrink.
- Heatshrink z-bends to the carbon rod, and heat. Put a drop of CA and allow it to wick into the heatshrink
- Don't try putting the z-bend in the center of a hollow rod, it won't stick.
- You can use a z-bend on both sides of the push rod. Center the servo, align everything, and heatshrink the z-bend in place. Once you're convinced everything is properly aligned, Apply CA.
- Somebody uses TIG welding wire for the rod.
- A lot of people use 1/32'' (almost 0.32) piano wire. These need to be fed through a housing to maintain stiffness. Attach the housing to the plane somewhere.
- The z-bends can be made from a paper clip or .072 piano wire.
- For a housing, try plastic coffee stirrers. Heatshrink together if you need them longer.
