Pit Tips

Cheap exhaust-tip plug

To prevent oil and fuel from spilling out, use a foam earplug as an exhaust-tip plug. Push it into the exhaust tip after you’ve finished running your vehicle for the day, and you won’t have to worry about spilling fuel and oil and making a mess.

Tire Tamer

Chevron-pattern tires provide great traction on softer terrain but can be rough handling on harder surfaces. With a hobby knife, make a series of small slits in the treads; this permits the treads to give a little, and you?ll have excellent traction, regardless of the terrain.

Better receiver seal

Dirt that accumulates inside your receiver can cause glitching. Open your receiver’s case, shake out the dirt, and then close it. Seal the receiver case’s seam with tape. Also cover the unused third channel or battery slot (if you run an electric car) with a clear piece of decal material or tape. This tip is also good for speed controls; you’d be surprised how much dirt can get in through the setup-button opening.

Dry-lube your CV axles

Lubing your CV-type driveshafts with grease attracts dirt, which makes them hard to clean after running the vehicle at the track. Instead of grease, use powdered graphite to lubricate the driveshafts. The dry lube will not attract dirt. Powdered graphite is available at most hobby shops that carry pinewood derby cars, or you can check the locks and door section of your local hardware store.

Better Body-Post Holes

The round rear body-post holes on many truggy bodies take a lot of abuse, and they tend to crack when the truck lands on its rear end. Make the holes oval so there is a little room for the body to flex during an impact. Doing so will make your body last much longer.

Superior sanding

If your slipper pads are glazed, you can revive them with fine-grit sandpaper. The tricky part is to be sure that you hold the pad flat so you don’t create low spots. The best tool for this job is the pressure plate that the pad is keyed to, or you can use an old spur gear, if the pad is keyed to the gear. Sand in a circular, polishing motion until the glaze has gone.

Hold Tight

A fuel line popping off can end your day at the races. To prevent this, place a 1/2-inch section of heat-shrink tubing over the fuel line before you attach it. Then slip the fuel line and tubing onto the nipple and shrink it for a nice snug fit.

Long-lasting glow-plug starter

Nothing beats the convenience of a rechargeable glow-starter, unless you forget to charge it. As a backup, keep a 1.5V lantern battery and model-airplane-type ?remote? glow starter in your pit bag. The glow starter clips to the battery with alligator clips, and one lantern battery can easily last a full six months of weekend racing. Mason Jennings, Tarzana, CA

Cheap and effective circle cutter

You can make a circle cutter from a 99-cent school-supply compass and a no. 11 hobby knife. Install the hobby knife in the clamp where you would normally put a pencil. Pass a screw through the graduated scale, and secure the screw with a nut on the other side. Once you have the compass set to the desired radius, tighten the nut to hold the setting while you cut. Perfect for cutting out cooling holes on bodies. Kevin Tuazon

Multiple car setups with one radio

Most computer radio systems have multiple model memories for storing setups. You can also use the model-memory feature to store different setups for just one vehicle. For example, have one model profile setup for asphalt and another for racing on carpet. Off-road racers can store setups for a variety of surfaces.
