Slotted Savage

Slotted Savage

It can be a real pain to get the radio box lid on and off an HPI Savage because the front shock tower is partially in the way. Use a rotary tool with a cut-off wheel to slot the two front holes on the radio box lid; that will make it much easier to remove and install.
Pin pliers

Pin pliers

It's easy to convert a pair of pliers into a roll-pin installation tool. Just chuck a cutoff wheel into your rotary tool, and cut a slot into one of the jaws of a pair of slip-joint pliers. When you squeeze the roll pin into the axle with the solid jaw, the slotted jaw allows the other end of the pin to pass through.

Shiny Shock Shafts

Shiny Shock Shafts

If the shock shafts on your car or truck are scratched, you can polish, or buff, out the scratches with a Scotch-Brite pad. A worn shock shaft can damage the O-ring seals in the shock; they'll then leak, and your vehicle's handling will suffer. A Scotch-Brite pad will remove most scratches and will buy you some time until you're able to pick up shiny new shafts.
Secure Battery Connector

Secure Battery Connector

All receiver battery packs have a male connector that mates with a female connector on the switch harness. Sometimes, a hard hit can cause the connectors to loosen or be disconnected, and this will cause your vehicle to go out of control. Install a piece of heatshrink tubing over the connectors to prevent them from being disconnected.

Two coats of glue are better than one

Two coats of glue are better than one

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.

No-crimp servo wires

No-crimp servo wires

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.
Convenient Charge Jack

Convenient Charge Jack

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.

Trash It

Trash It

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.
No more E-clips

No more E-clips

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!
