RECOMMENDED TOOLS AND SUPPLIES
This section lists the recommended tools and supplies that you need to purchase and have onhand to finish assembling and to run and
maintain your new Mammoth ST Nitro Stadium Truck. We have tested these items extensively with the Mammoth ST Nitro Stadium
Truck and found that they offer the best in reliability and value.
WHAT FUEL DO I USE?
Fuel can make a big difference in the way your engine performs. For the break-in period you should use a fuel specifically designed for
R/C car engines that contains no more than 20% nitromethane. Once the engine has been adequately broken in (about 45 minutes of
run-time) you can switch to an R/C car fuel containing up to, but no more than, 30% nitromethane.

✦ We do not recommend using fuels designed for R/C airplane engine use. These fuels do not contain the proper
amount of lubricants; therefore, they will cause the engine to overheat and severe damage to the engine will result.
DO I NEED TO PURCHASE EXTRA GLOW PLUGS?
Yes. Even though your XTM Racing 24.7 comes with a glow plug already installed in the engine, glow plugs
wear out, especially during the break-in period; therefore, it's a good idea to have a couple of spares handy.
We recommend using a "medium" or "hot" heat-range glow plug intended specifically for performance
engines like the XTM Racing # 3 (P/N 146020 ) during the break-in process. After the break-in period you
may want to use a different heat-range glow plug. Use a colder glow plug like the XTM Racing # 4
(P/N 146021) if you're using 30% nitro fuel. Do not use glow plugs intended for four stroke airplane engines
or glow plugs with an "idle bar". Using the wrong type of glow plug will cause the engine to run erratically and make it difficult to tune
properly. The wrong type of glow plug could also damage the engine. AN XTM RACING # 3 GLOW PLUG IS INCLUDED IN THE ENGINE.

(use this fuel for break-in and normal use)
XTM Racing 30% Nitro Car Fuel - P/N 145851
(use this fuel after break-in for more power)
DO I NEED TO USE A FUEL BOTTLE?
Yes. Because fuel is packaged in quarts or gallons, you will need to use a smaller
bottle with an extension wand to fill the fuel tank. Fueling using this method is much
easier and a lot less messy. The XTM Racing 500cc Fuel Bottle is a good choice.

HOW DO I REMOVE THE GLOW PLUG?
A long reach glow plug wrench is necessary to easily and quickly remove and replace
glow plugs. The XTM Racing 1/8th Scale 4-Way Wrench works great.

WHAT DO I USE TO IGNITE THE GLOW PLUG?
A glow starter is a battery-operated device that, when attached to the glow plug,
heats the glow plug so that the engine can start. The glow starter is then removed
after the engine is running. The XTM Racing Glow Starter with Meter is a perfect
choice. It comes complete with a battery, charger and a built-in meter to let you know
if your glow plug is good.
