Default 1/12 battery and motor rule question NIMH and brushed motors

If I wanted to race just for fun, are NIMH and brushed stock motors still ROAR legal for 1/12th scale? I know the performance disadvantage, but I really just want to turn laps during the winter months.

Thank you

Most classes will call out a specific type of motor and battery. For example, 1/12 17.5 1s is a very popular class. In this case, your car would not be legal.

But you should check with the group you are racing with. Many club racers would not mind you running your car with them, just to get another car on track. We had one racer running 4 cell 27T brushed with us for quite a while before he upgraded to a brushless motor and LiPo battery. We were happy to have him, and it added to the fun.

As long as you aren't running something that would give you an advantage I think a lot of club races wouldn't mind. Of course if it's a sanctioned event that would be a different story.

Check with your local track, not a legal combination anymore but at the local club level an exception may be allowed.

I'm not sure why anyone would complain about your performance disadvantage.

--------

You could upgrade to lipo for about $120 +shipping from HobbyKing

Trackstar One Cell ESC $48
Turnigy 1s A-SPEC lipo battery $25
Turnigy Trackstar 17.5 motor $33


edit: forgot about a charger that can handle Lipo, that'd have to factor into the cost if you don't have one

It may sound like a good idea, but I don't think you would have any fun.

12th scale is now single cell LiPo (1S) which is 3.7 volts. 4 cell NimH is 4.8 volts.

If you're running NimH cells from "back in the day," you're better off throwing them right in the trash. They're not going to perform anywhere near what they used to. I doubt they will last 8 minutes.

If it's a permanent track, go on a practice day first and see how everything runs. Then check with the locals and see if they'll let you run.
