| It's great that many RTR vehicles have glued tires, but it's also a good idea to run a second bead of CA between the tire and rim. Let the glue dry before you run your vehicle. By doing this, you'll ensure that the tires stay bonded to the rims even during hours of running. |
| Zip-ties work fine to protect your engine's cooling head, but there's a better method, Run fuel tubing around the top of the cooling head as shown, and secure it with zip-ties. It looks better and will offer more protection. |
| Most sealed radio boxes have an opening through which the servo wires go, but on some models, the opening is so small that the wires get crimped when you close the radio-box lid. To remedy this, enlarge the opening with a hobby knife or a Dremel tool with a rotary sanding bit. |
| You can make a convenient charge jack by soldering a male battery connector to your receiver battery pack. Solder the positive and negative leads from the connector to the corresponding positive and negative leads on the wires on the receiver or directly to the cells. |
| Nitro vehicles can get really messy after a day of racing, and tossing a dirty car in your trunk or back seat can leave permanent stains on the carpet and upholstery. Place your car or truck in a garbage bag after you?ve finished racing for the day. The garbage bag will prevent dirt, oil and other grime from spilling out in your car. Eight-gallon bags fit everything from for 1?10 trucks to 1?8 buggies; use 13-gallon bags for larger monster trucks and truggies. |
| Instead of relying only on E-clips to keep your car's hingepins in place, add a 4-40 setscrew for extra security. To do this, drill a hole in the arm mount or hub carrier (whichever part has more 'meat') so the setscrew will intersect the hingepin bore, and drill the hole slightly smaller than the setscrew so it will thread properly. Next, grind a flat spot on the hingepin where the setscrew pinches it, and assemble the parts so the setscrew tightens against the flat. No more lost hingepins! |

| To make shock coverings (usually a balloon or finger from a latex glove) easier to install, wrap your spring in electrician's tape, leaving about a 3-inch tab hanging off the bottom of it. Now, with the tape in place, the shock covering will easily slide over the spring. Once the shock covering is in the proper position, just pull the tab and the tape will unravel off the spring, and the covering will stay in place. Brad King Allison Park, PA |
| The 4-cell receiver battery-pack holders that often come with nitro kits work fine, but AA cells can pop out of the holder during hard running. If a cell pops loose, it can cause a loss of signal. To prevent this, wrap electrical tape around the battery pack. The tape will hold the pack securely in place even during the hardest driving, but it will still be easy to remove.

| On most nitro vehicles, you have to reset the gear mesh whenever you reinstall the engine. If you thoroughly clean your vehicle after every day of running, you'll have to set the gear mesh quite often. If you know your gear mesh is perfect, before you remove your engine, scratch lines on the bottom of the chassis plate to show exactly where the engine-mount screw heads are. Next, fill these scratch marks with a bright paint, and wipe off the excess. Now, you'll be able to quickly reinstall your engine with confidence, knowing that your gear mesh will be perfect.

| When running big breather holes in off-road tires or even small holes on touring-car tires, small rocks sometimes work their way into the rim and get trapped. To prevent this, glue a small piece of window-screen mesh over the opening. This will allow air to pass freely but will prevent debris from getting in and adding weight, or setting the wheel out of balance. Peter Bedford Fairfax, VA |
| Forgot your ride-height gauge? No problem; you can use the change in your pocket to adjust your touring car?s ride height. For asphalt, most racers set up their cars with a 5mm ride height. A stack of three quarters or four dimes equals 5mm. Set up the stack of coins, and lower or raise the ride height until the chassis just grazes the coins as it rolls over them. |
