thank you! Any help will be appreciated!

PS. is any of the diagrams(ie. speed controller, Robot contoller,etc.) on the Robot Power Distribution diagram available to make a custom diagram?

thanks again for any help!

Connecting two motors to the same speed controller can result in damge to the controller, hence the rule R77. Some teams have reported using a PWM "Y" cable, that is the PWM output from the RC is split to two controller PWM inputs. My team has not used this method, and prefers to have each motor fed from it's own PWM. It is essential that the controllers for both motors in a dual motor transmission be calibrated, so that efficient operation can be accomplished. (one motor does not fight the other resulting in reduced speed and power and increased current.)
