How to Build an Axle on an RC Airplane
- 1). Measure the diameter of the holes in the center of the wheels to ensure it matches the diameter of the rod. The aluminum rod needs to fit through the holes, but shouldn't be too loose or too tight, otherwise the wheels will not spin correctly.
- 2). Consult the plan to determine how long the axle needs to be. The wheels will need to sit under the fuselage, but may protrude slightly. The distance depends on the size and weight of the plane. The plans will contain the exact specifications required.
- 3). Measure the distance from the end of the rod to the desired length and leave a small pen mark on that spot. Cut the rod with the hacksaw. Use the file to remove any sharp, pointed edges from the end.
- 4). Thread the collars onto the axle, followed by the wheels. The collars are small metal circles that fit on one side of the the wheel and hold it into place by interlocking with the screw on the other side. Thread on the screws and tighten them into the collars. Do a test spin to make sure the wheels move correctly and are not too tightly mounted.
