Nitro to Brushless Buggy/Truggy Conversion

[MetalMan]

Welcome to RC-Monster!

First off, do you have the original X-Terminator or the XT2?

You can't decide gearing until you know what battery you will be using.

I'm not so sure any of the FD mounts will be able to properly hold the CC MMM motors. Around here the much-preferred method of holding the motor is by using a motor mount that replaces one of the center bulkheads, and supports the center diff. This setup is much more secure and a lot less prone to any issues related to chassis flex between the pinion and spur.
