Making a Carbon Fiber Push Rod

What you need:
  • carbon fiber rod, 2mm, cut to length
  • 2 pieces music wire, .032i inch (.81mm), 2 inches each
  • screw thing:                1.5mm 
  • 5 minute epoxy


Make the push rods:
  • measure length required
  • cut CF rod, length = measured length - 1 inch (wire will make up remaining length) using dremel cutoff wheel.
  • cut 2 pieces of wire, 2 inches each
  • put a tiny irregularity (bend) in one end of each wire.  this will go into the CF tube, and provides something for the epoxy to hold against.
  • clean wire
  • mix 5-minute epoxy
  • epoxy wire into CF rod, 1 inch.  don't forget to put the tiny bend into the hole.
  • after the epoxy has dried, tug on the two wires to make sure they don't slide out of the hole.  If they do, you didn't do a good job on the epoxy.
Install the push rod:
measure length required
  • Z-Bend one wire.
  • attach z-bend to servo. (then you don't have to drill out hole in servo arm).
  • drill horn to fit 1.5mm screw thing
  • attach screw thing to horn
  • put straight wire into screw thing.  you can get clearance by pushing servo arm away from the control surface, and pushing the control surface away from the servo arm. this will give you just enough clearance for the wire to go into the screw thing hole.  if there's not enough clearance, your wire is too long and you should trim it down to the proper length where it just fits in.
  • turn on servos so they are centered
  • align control surface to neutral position
  • screw down screw things
Hint: if you know you're going to be needing several sets of push rods, make all of them at the same time, factory style.  You'll save lots of time.

    Build A Flying Wing For Less Than $5 | The Hobby Guy

    Build A Flying Wing For Less Than $5 | The Hobby Guy:
    "I am always happy to make things from cheap parts, especially when you add up all the money I spend on my hobbies. Building radio control airplanes from BlueCor (Fan Fold) foam board keeps cost down.

    In addition to being low cost, Fan Fold airplanes are fast to build and easy to repair. This build should take less than two hours, and sans electronics, cost under $5.00. Compare this to commercial kits, which start at $40.00 for a box of foam. Forty Dollars is not a bad price, very good in my book, but you can build eight wings for the same price."
