Pit Tips

Jewel-box crystal case

Here’s a clever way to keep your crystals safe and organized. Take a CD jewel case and remove the section that held the CD. Next, use a hobby knife to cut out small squares of thin foam rubber (toolbox drawer liners work great) as shown. A typical jewel case can easily hold 35 crystals.Norbert Carter

Electric toothbrush parts cleaner

Here’s another great tip from Justin: use an old electric toothbrush to clean RC parts. The rotating bristles clean off the tough-to-remove stains on tuned pipes and other parts that have built-up fuel and dirt. Spray a little WD-40 onto the bristles and make suspension arms and other plastic parts look like new.Justin Scheller – San Juan

Savage switch extender

CLICK IMAGE TO ENLARGE
The HPI Savage on/off switch can be hard to reach, especially with the body on. Attach an old servo horn to the switch, as shown, to make it easier to access. You’ll have to cut a rectangular slot in one end of the servo horn and then move the switch so that it’s centered?neither on or off. Position the horn on the switch, and mark the radio-box cover where a machine screw must pass through to hold the horn in place. Use a screw and a locknut to secure the horn. The screw must be snug but should still allow the switch to move freely from left to right. Garvy Jones – East Palm Beach, FL

Handcart back-saver

If you’re a diehard nitro racer, you probably haul a lot of equipment to the track. Sometimes, the trek to the track is long, and that makes carrying stuff a pain (literally!). Take a handcart with you so that you can roll your gear. Your back will thank you

Homemade nitro cleaner

You can make your nitro-car cleaner easily and affordably by mixing two parts denatured alcohol with one part Simple Green. Store the cleaner inside a pump spray bottle, and top off the brew with a capful of WD-40. Be sure to shake the bottle before every application because the solvents separate over time. One gallon of denatured alcohol and a 2-liter bottle of Simple Green will make enough nitro cleaner to last months

Protective-film body repair

Associated’s clear protective film (item no. 6312) also works great to repair cracks and holes in Lexan bodies. Just cut a piece out and stick it on the crack in the body. The film will last a long time, and one sheet can be used to repair many bodies

Zenoah pull-starter protector

The pull-start housings on Zenoah and other similar gasoline engines have intake vents that feed air to the internal cooling fan. Unfortunately, these vents can suck in small objects such as rocks and leaves that may clog the intake, or worse, damage the pull-start mechanism and cooling fan. The best solution is to apply mesh window screen (available at most hardware stores) to the inside of the pull-start housing to prevent objects from entering. Use Pacers’ Zap-a-Dap-a-Goo to glue the screen in place.Michael Lawlor

Simple EZ-Start glow-plug connector

The blue glow-plug wire on various Traxxas models equipped with the EZ-Start system is difficult to connect and remove, and the shrink-wrap always gets damaged by using pliers to grip the wire. To simplify things, cut the connector from the coil, and solder an alligator clip to the end of the wire. Bend the teeth inward at the tip of the clip for a better fit.Markel Andersson

Recycled shock-fluid bottles

Clean empty shock-fluid bottles with soap and water to remove the fluid left inside. You can use the bottles to store liquid dishwashing soap for off-road tire cleaning at the track. One bottle holds enough soap to clean dozens of tires

Revive your Dremel tool bits

Dremel sanding drums and tool bits can easily become glazed and dulled with normal use, especially if you grind a lot of plastic and Lexan. These materials melt quite easily from the friction of the sanding, and that can leave a mess of melted plastic on the drum. I’ve seen racers throw away those bits, and that is a waste. You can usually bring a Dremel bit back to life by grinding the surface with a diamond-faced file (available at most hardware stores). Install the bit on the Dremel, and spin it at 3/4 speed. Use the file to remove the glazed-over sections or melted plastic.
