Jammin X1CR Brushless conversion
 

Hey all have a Jammin X1CR which I am converting to brushless, will be running a 4s 5000mah Lipo, Quark 125B speedy no UBEC, Spectrum radio and Medusa 36-60-2000V2 motor wondering what pinion to use.

I have the following Mod 1 Pinions at my disposal:

11, 12, 13, 14

Any thoughts? I like my gear to run cool hence the Medusa motor.

Welcome to the forums!!!

Yeah thanks for the links, looks helpful for gearing to speed, but I am more seeking a reliable basher that doesn't run hot, hence why I chose a Medusa motor.

I am more looking at a good gear ratio to be able to bash it around and not have to be watching it every 10 seconds with a temp gun in hand!

13 or 14 would be my guess.
