This is V2. I rotated the motors 90 degrees and moved them closer to center. I also raised them .050". Now there is much better link clearance.

This is to mount two gear reduction motors in an ecx barrage or like rc crawler. Greatly slows it down for much more controlled crawling. Big improvement over stock. You have to either shorten the drive shafts or motor shafts slightly. Also you need to shave the links that mount under the motors. Uses factory hardware. No need to use screws to mount the motors. I used 300rpm motors. You can use the factory esc. Also you have to switch polarity on one of the motors. I'm thinking a higher rpm motor will be better for wheel speed. I'll be experimenting with that
