This tip comes from the Losi camp: the Triple-XNT AD1, RTR and RTR 2 have slightly oversize fuel tanks that aren?t ROAR-legal. To bring a fuel tank down to 75cc capacity, put a 12-inch length of fuel line with its ends capped with 3mm screws into it
The quick-fill caps on some fuel tanks won’t close or seal completely when the rubber O-ring inside the cap is new or just dry. Some lids are adjustable; if yours isn’t, apply a little grease to the O-ring to allow the cap to close completely and provide a better seal.
When a monster truck’s foam inserts get wet, the tires wobble badly. Bubble wrap?the type used for packing?works well as tire inserts and doesn’t absorb moisture as foam does. Use the ‘smaller’ bubble wrap, and layer it over the rims. It takes a little effort to make it fit properly, but it’s well worth the minor hassle. D. Clark – Chicago, IL
Stones and other debris can enter through the opening in the chassis under the motor and get caught between the gears. To prevent this from happening, cut a 35x46mm piece of scrap Lexan and lay it under the motor. The motor will keep the Lexan in place, so there’s no need to glue it, and it will protect the gears from the elements.
The tubes that tennis balls are sold in are the perfect size for storing touring car tires. The tubes can hold four or five pairs of tires; stick labels on the tubes to let you know which tire compounds are stored inside.
Model Master, Pioneer Plastics and a few other companies sell clear-plastic display cases for 1/24- and 1/18-scale plastic and die-cast static models that work great for displaying your micro machines. The cases keep your cars dust-free until you’re ready to race, and they’re available at most hobby shops. Some even have accessories such as lighting kits and different backgrounds.
Add a cell to your glow igniter to double its capacity. You?ll need to do some grinding and soldering, but the results will be worth it. Solder the cells in parallel, as shown, and use Shoe-Goo to glue them together. Two 3300 cells wired in parallel will provide 6600mAh. That?s enough to last for weeks of racing.Hendra M.

The Losi Triple-XNT Sport 2 has a great electric engine-starting system, but you have to lift the body to insert the tip of the shaft into the drive dog on the backplate. Cut an oval hole in the body so that you’ll be able to pass the tip of the starter shaft through without lifting the body
The Mini-T’s antenna holder can lose its grip on the antenna tube, and that will cause the antenna to slip off the mount. To fix this, drill a small hole through the antenna holder, and thread in a small screw. The antenna tube will stay put.
