Adjusting the Slipper

4-Turns Out

The slipper is a key component of the drivetrain that is 

designed to help absorb sudden or large impacts that would 

otherwise stress various drivetrain parts. You should never 

run the Speed-NT with the slipper locked (completely tight). 

The slipper can also be used as a tuning aid for extremely slick 

conditions. To adjust the slipper, start by turning the 1/4-inch 

adjustment nut clockwise (tighten) until it gets tight and the 

spring is compressed. Do not over-tighten as you will strip the 

nut. Now turn the adjustment nut counterclockwise (loosen) 

four (4) full turns. This should be a good overall setting.

Maintenance

In addition to the service needs pointed out in this guide, 

you should try to maintain your new Speed-NT for proper 

performance and to prevent wear. If dirt gets in the moving 

parts it can seriously hinder the performance of the model. 

Use compressed air, a soft paint brush and/or a toothbrush 

to remove dirt and dust. Avoid using solvents, if possible, as 

this can actually wash the dirt into bearings and areas not 

accessible without disassembly, causing additional wear. We 

suggest you follow these basic guidelines:

• 

Remove as much freestanding dirt and dust as noted 

above.

• 

Never leave fuel in the tank for more than a couple of 

hours.

• 

When done running for the day or longer, let the engine 

run out of fuel. Remove the air cleaner and spray a little 

water-displacing lubricant, or quality after-run engine 

oil into the carburetor and spin the engine over a few 

seconds.

• 

If needed, clean and re-oil the air cleaner before installing 

it back on the model.

• 

Inspect the chassis for worn, broken or binding parts and 

repair as necessary.

Storage

When you are done running the Speed-NT for the day:

• 

Blow it off with compressed air and/or use a soft bristle 

paintbrush to remove dust and dirt from the chassis.

• 

Use your fuel bottle to remove any remaining fuel out of 

the fuel tank.

• 

If the model is going to be stored for an extended time 

period unplug the receiver battery and remove the 

batteries from the transmitter.
