In our demonstration, we selected two different types of RC racers in order to represent two separate drivetrain designs. Both cars utilize two-speed transmission and disc brakes. The Nitro Razor, however, uses a driveshaft (figure A); the Duratrax Street Force uses a drive-belt system (figure B).
Assembly of the Duratrax Street Force - First, turn the chassis over and tighten all the screws on the bottom with a small Phillips screwdriver. The screws hold the engine on the chassis. You may want to loosen each one, apply a little thread-lock and retighten.
- Apply after-run oil in the carburetor and glow plug.
- Thread the wire antenna through the antenna mast and mount it in the mast holder by pressing it firmly into place.
Tip: Spread a small amount of talcum powder or cornstarch on the wire antenna to make it easier to slide into the antenna mast.
- Install four AA batteries in the radio receiver.
- Install eight AA batteries in the radio transmitter.
Once you've completed basic preparation on the chassis, you can begin trimming the body.
Applying Body Trim
Since this particular model comes with an unfinished body, it allows you to customize its appearance as you wish, using the decals that come with the kit. - The body comes with a protective plastic film applied to prevent it from getting scratched during shipping or unpacking. Carefully peel off the protective film (figure C), revealing the glossy finish underneath.
- Carefully cut out the decals you select from the decal sheet (figure D), using scissors. Decals may include headlights, windows, grill, racing stripes, logos, etc.
- Prepare the area where you'll be applying the decal by spraying it with a solution of water and a few drops of dishwashing soap.
- Peel the backing off the first decal and position the decal where you want it to go (figure E). The slippery soap-and-water solution permits you move the decal around on the plastic surface, straightening and making slight adjustments to the positioning.
- Once the decal is positioned just like you want it, gently blot it with a paper towel to remove the excess solution. The decal should bond to the surface as it dries.
- Repeat these steps for the other decals you've selected.
Once all the trim has been applied, you may want to cut holes in the front and rear windshields (figure F) to permit enhanced airflow and cooling of the engine during operation.
With the trim on the body complete, the antenna mast installed on the chassis (figure G) and the batteries installed, place the body on the chassis (figure H) and fasten it down with the body clips provided (figure I).
Important: There is likely to be a length of antenna wire extending beyond the end of the antenna mast. Do NOT trim off the excess wire. Shortening the antenna wire will reduce the radio-control range significantly.
