Bruder Mini compact roller conversion

cults3d

This is my design to have both drums motorized. there is a vibrating n20 motor under the seat. the steering is done with a servo mount in the front and a servo attachment on the rear part of the roller as shown in pictures. you will need some small 1/2 ounce weights to put in the barrel to add weight. requires a very small 800 mah 2s battery along with a 6ch receiver. it all fit but does require some good cable management. and lastly 2 esc's to run the motors. I suggest using the tinyesc from robotshop. lastly a BEC if you want to keep it all under the 6v. you should check that your tolerances are accurate so that the drum slides in tight but not to tight. you can use CA to glue it in place. also a set screw to hold the motor shaft to the wheel. any questions please feel free to ask.
