Fixing the Chevron's Stubaxles
by
Daniel J. Dyke
I have started my next generation Fly Chevron. Five changes were made from the last event at Pzooc's house. The major change to the car was to make an alternate stub axle system to keep the front tires from bouncing. It was installed on the one Chevron I had that night, but it was not run except in practice. Usually on Fly classics people put a straight axle in the front, but this can't  be done on the Chevron as there is a body mounting post in the way.





OPTIONS

Two options presented themselves: remove the post and install a straight axle or fix the stub axles by making a better setup.  The second option was chosen as I don't like to permanently alter the body on a car, especially a Gunston liveried car.  

PARTS

Other than what is on the car and the necessary tools, you will need an extra axle and two 3/32" inner diameter collars from an RC store. Dubro makes and sells a package that contains several collars and an allen wrench for a less than $2.00.

PROCEDURE

  1. Remove the stub axles and the wheels from the car.
  2. Cut a regular axle in half and chamfer the ends of both halves so they slide smoothly through the axle holder on the chassis and fit deeply into the wheell. Spin the axle in the holder to see if it moves easily and also wiggle them to see if they fit loosely.
  3. Take the two stub axles you made and glue them into the front wheels. You can do this aggressively because they are out of the car. Use a fine grade sandpaper to get any excess glue off the axles once they dry. Make sure the axles are all the way in the holes of the wheels.
  4. Cut any flashing off the inside of the axle holders and sand them smooth.
  5. Slide the axle in, put the collar on and note how much excess axle there is and remove the axle.
  6. Cut each axle to the proper length, reinsert them into the axle holders, slide the collars on and tighten the set screws. 
  7. Check to see if the axle spins freely. Loosen the collars slightly if needed.  Lubricate the axles.
