Rock Crawler servo adapter parts

thingiverse

Adapter to convert a cheap 1:18 non-proportional steering rock crawler like HB - P1803 (https://www.gearbest.com/rc-cars/pp_227935.html) to proportional. Need a brushed ESC; a receiver & transmitter, a standard micro servo. Ditch the steering motor, attach the servo on top of the front axle using the plate thingy, push the "ServoSpacer" ring into the push rod hole to make the servo screw fit nicely. I'm using the car with 2S LiPo batteries, with the new ESC my motors died pretty quickly, better get some replacement 130 motors (1 per axle needed for this car) before upgrading. I happened to have an unused pair of some dirt cheap toy RC helicopter motors, they were slightly bigger than the stock ones but fit fine after some quick carving, and have survived a lot of hard driving.
