When adjusted properly, you should be able to hold
the rear tires irmly and barely be able to push the spur
gear forward with your thumb. To track test, turn the
Micro-T on and place it on the ground. As you push it
backwards, allowing it to roll freely, punch the throttle.
The slipper should slip no more than an inch or two as
it accelerates. Make sure you replace the gear cover
before running.
Steering Rate
Your transmitter is equipped with a steering rate control to the left of the steering wheel. This
advanced feature, usually found only on competition-type radios, allows you to adjust the amount
the front tires move when your turn the steering wheel. This is really helpful when you are on
slick as well as high traction surfaces. If your Micro-T turns too sharply and/or spins out easily, try
turning the steering rate down by rotating the knob counterclockwise (to the left). For sharper or
additional steering, try turning the knob clockwise (to the right).
Steering Trim
The Micro-T should go straight without turning the steering wheel. If not, rotate the ST.Trim knob
located to the top right of the steering wheel in the direction needed for the truck to go straight.

Cleaning
Performance can be hindered if dirt gets in any of the moving suspension parts. Use compressed
air, soft paintbrush, or toothbrush to remove dust or dirt. Avoid using solvents or chemicals, as
they can actually wash dirt into the bearings or moving parts as well as cause damage to the
electronics.
Rebuilding the Differential
The gears in the differential will wear over time. The same is true for the outdrives, driveshafts,
and rear axles. We suggest using a small rag or paper towel to lay out the parts you remove to
make it easier to reassemble.
1) Unplug the motor. 2)Remove the gear cover (three screws). 3) Remove the motor guard
screws at the top of the transmission and the two lower extreme rear bottom of the chassis. 4)
Remove the screw that attaches the rear shock tower to the transmission and the 4 long lat-
head screws at the bottom of the chassis that hold the gearbox in place and slide it out of the
Changing the Spur Gear
Remove the gear cover by removing the three small screws. Remove the slipper adjustment
nut at the end of the slipper shaft and all of the slipper parts on the outside of the spur gear as
well as the old gear. Place the new spur gear into position and replace the slipper parts. After
you have changed the spur gear, you will have to adjust the slipper as described in the “Slipper
Adjusment” section on page 3.
Changing the Pinion Gear/Gear Ratio
Before you change the pinion, ask yourself why you are doing it. In general, if you change to a
larger pinion the top speed will improve, but you will see less acceleration and run time. This
would only be advisable for really long track layouts with few tight turns. Changing to a smaller
pinion will give you quicker acceleration and possibly a bit longer run time but a little less top
speed. This would be good for real short layouts or when running faster motors. The pinion that
is on the Micro-T offers the best balance of both. To change the pinion remove the gear cover,
loosen the motor screws, and slide the motor back. Use a small lat head screwdriver between
the motor plate and pinion gear to push the gear off. Place the new pinion on the end of the
motor shaft and press the new pinion gear into the same position as the one removed.
chassis. 5) Remove the left side of the gearbox by removing the three screws. 6) Follow Figure
1 below to rebuild the differential (Use LOSA3066 Grease). 7) Once the differential has been
rebuilt, assemble the transmission by following the steps in the reverse order. Be sure to use the
screws in the same location that they were removed.
Setting the Gear Mesh
The motor screws should be slightly loose. Slide the motor forward allowing
the pinion gear to mesh with the spur gear. Snug (not tight) the bottom mo

tor screw and try rocking the spur back and forth. There shoud be a slight
bit of movement before the motor is forced to turn over. If not, pull the top of
the motor back slightly and recheck. If there is too much slop between the
gears, push the top of the motor forward. When set properly, the wheels can
be spun forward freely with very little noise. Make sure to tighten both motor
screws and replace the gear cover before running.
Radio Replacement/Service
If you have a radio problem please call
1-(877) 504-0233 for customer service.
Most likely,
unless you have gotten the components wet the service technician can help you ix the problem
over the phone. If the problem is more severe, you may be asked to send in the truck and trans
