You can make a universal starter box by attaching a thin “L” bracket to one side of the starter-wheel opening on the starter-box platform. The bracket will fit through the flywheel opening in the chassis and lock onto the vehicle. No need for starter-box pegs!
If you run your Team Associated L4O on a very small track, you might need more right front camber than the stock suspension allows. To get more camber, file down the two upper-arm pieces so the turnbuckle can be threaded in farther. James Day Dover, DE
To accurately measure shock and turnbuckle lengths, spring preload, tire diameters and other critical components, you need an inexpensive set of calipers. They're also great for measuring the lengths of screws.
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.
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.
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.
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.
