It’s a spec motor, your supposed to use it out of box without any changes. Ceramic bearings would be a hop up on the motor

At bigger races for indoor carpet USGT, are people using ~5200mah 240-245 gram packs or using 5800-6000 packs around 285-295?

I use whatever weight battery I need to balance my chassis. I use a 5800/245 gm pack in my TC and a 7000/285 gm pack in my USGT.

USGT isn't a ROAR class.

5800's are the hot ticket right now. Ultra LCG and weigh in around 242g or so. Discharge curve is nice and have great IR's.

Awesome, thanks guys. Is the 5800 R1 battery (~245g) the only option in that weight/mah range?

This is the gravity RC usgt motor

Better keep a very close eye on the Serpent guy in particular.

Has anyone ran the Montech Racing Akura GT3 yet? Been wanting to try it out but haven't heard or seen anyone running it.

It should be illegal to change anything on that USGT motor, there's a reason why its a spec class motor and adding ceramic bearings to it is flat out cheating.

So what bearings can you run then when/if they get gritty?

Stock only? Avid? some other brand? Have to buy a new motor?
Can you clean and lube? can you pull a shield? Can you run rubber shields or only steel or vis-versa?

Surprised ceramic single shield aren't banned in the car too.

Where do we stop and just admit we lost, not because someone had 'other' stuff?
