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
- Remove the stub axles and the wheels from the car.
- 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.
- 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.
- Cut any flashing off the inside of the axle holders and sand them
smooth.
- Slide the axle in, put the collar on and note how much excess
axle
there is and remove the axle.
- Cut each axle to the proper length, reinsert them into the axle
holders, slide the collars on and tighten the set screws.
- Check to see if the axle spins freely. Loosen the collars
slightly if needed.
Lubricate the axles.
