**Note: You MUST be an experienced marshal over the age of 14 to marshal the gas heats and/or mains.**

**Final note:  1/8 electric late model class allows nitro cars to run with the electrics. So to add extra runtime cushion a larger tank can be installed, enough to run an extra minute or so to allow a few hot laps lap and still finish the race easily and not need to always be topping off. If nitro class ever runs again the stock tank may need to be reinstalled because this is one difference from nitro that does not concern electrics. Right now Nitro late model rules say no larger tanks**

Duratrax Bandito 1/8 Buggy
Dynamite Robbers 1/8 Buggy
NOTE: Over the years we have tried other tires. So we will now accept any GT tire that does not have a belt and is legal for 1/8 GT Racing

Section 8: Weight

8.1: 8-1/2 lb. At any time

**Note: You MUST be an experienced marshal over the age of 14 to marshal the gas heats and/or mains.**

**Final note:  1/8 electric late model class allows nitro cars to run with the electrics. So to add extra runtime cushion a larger tank can be installed, enough to run an extra minute or so to allow a few hot laps lap and still finish the race easily and not need to always be topping off. If nitro class ever runs again the stock tank may need to be reinstalled because this is one difference from nitro that does not concern electrics. Right now Nitro late model rules say no larger tanks**
