TESTING THE RANGE OF THE RADIO SYSTEM
It is important to test the range of the radio system before driving the micro truck. This will let you know if there is any interference in the signal between
your transmitter and the truck, or if the batteries are low. It is best to perform a range test with 2 people.
1. Make sure that the transmitter batteries and receiver pack batteries are fully charged.
2. Turn on the transmitter, and then turn on the ESC.
3. Have someone hold the truck while it is running. Make sure s/he holds it safely.
4. While near to the truck, operate the throttle/brake and steering controls.
5. Walk away from the person holding the truck, and continue to operate the controls. The truck should respond to your transmitter without glitching.
6. Continue to walk away, still operating the transmitter controls, until the truck stops responding to your transmitter or it starts behaving erratically
(glitching).
7. Walk back towards the person holding the truck until the truck again responds properly to your transmitter. THIS IS THE MAXIMUM SAFE RANGE OF
THE RADIO SYSTEM.
8. Turn off the ESC, and then turn off the transmitter.
To tighten the front differential you need to remove the RIGHT front upper arm to give
access into the diff for adjustment with the included Phillips screwdriver. Insert the
screwdriver tip into the differential adjustment screw, hold the left front wheel fi rmly and
then tighten (CW) the screw as required.
Please note that the factory pre-assembled ball differential is pre-built but is NOT tightened. To enjoy long life and smooth performance of the differential, you need to break in
both front and rear differentials properly. You will need to run the truck several times for a short time, and each time tighten both differentials a small amount.
DIFFERENTIAL SETTING
To tighten the differentials, remove the front/rear upper arms as described below, and use a Phillips screwdriver to tighten the diff adjustment screw.
BREAK-IN PROCEDURE
1. Run the truck for the fi rst time at only ¼ throttle for 30-60 seconds.
2. Tighten both front and rear diffs slightly by 1/16 turn.
3. Run the truck again for 2 minutes at ¼ throttle.
4. Tighten both front and rear diffs slightly by 1/16 turn. The differential should still turn freely.
5. Run the truck again for 5 minutes, this time up to ½ throttle.
6. Again tighten both front and rear diffs by 1/16 turn.
Now the differential should be tight enough. The differentials should still turn freely but must still slip slightly with higher resistance.
To tighten the rear differential you need to remove the LEFT rear upper arm to give
access into the diff for adjustment with the included Phillips screwdriver. Insert the
screwdriver tip into the differential adjustment screw, hold the right rear wheel fi rmly
and then tighten (CW) the screw as required.
HOLD TIRE
HOLD TIRE
Remove the screw from the top of the RIGHT front steering block or LEFT rear upright.
After removing the screw, lift the upper arm to allow the drive shaft to disconnect from
the differential. You can now fi t the screwdriver into the ball diff.
