Default Gearing for RC12R5?

I'm a noob when it comes to pan cars, so I need some help with this. With a stock spur on a RC12R5, what tooth pinion should I use with a 19T brushed motor for a tight track, obviously on 1s?

Thanks for the help!

Mitchell

You may be able to search the threads and go back 7-10 years and see what gearing was being run.

the problem is 19t went away to brushless before 4cells went away to 1s, but 45 to 50mm rollout might be a start? what ESC do you have than can operate brushed with 1s lipo?

Any brushed ESC will work if using a receiver pack. An external low voltage cut-off device would help though.
