Built For Combat From the Ground Up!
Months of work have gone into making the most durable motor possible to fit into a beetleweight (or even bigger) combat robot, and this is the result. In larger weight class bots there are many modifications frequently made to motors to help them survive the rigors of combat. Boring out the motor to fit larger bearings, larger more durable shafts, removing circlips and set screws, and adding epoxy to the magnets all to battle harden these motors. Now for the first time ever, you can buy a motor off the shelf with all of these changes and more! Download the JCR-4935 CAD here, plus Subtraction's blade and shock mount designs here.
What's Included:
- 1X JCR-4935 motor, combat-ready out of the box!
- 6X Alloy Steel M5 x 12mm flat head screws
- 4X Alloy Steel M5 x 10mm button head screws
- 4X 6mm diameter x 10mm length hardened steel dowel pins (these will be a slip fit with the top of the motor, and must press fit into blades or whatever else you are attaching on top).
- This motor is intended to be mounted to a rigid robot frame component and as such does not come with a mounting plate or bracket.
