Description
This gear motor is meant for Beetleweight Combat Robots.
The planetary motor is solid and robust enough for combat conditions.
Notes:
– Full metal gears, with grease.
– Solid construction with very thick gear body.
– 4 Through body bolts hold the gear body together.
– All screws are set with locktight
Specs:
Voltage ~12v
Suitable LiPo: 2s and 3s
Weight +-71g
No Load Speed (r.p.m): 789 +-10%
Rated Load Speed (r.p.m): 631 +-10%
This has been tested with the 20A ESC Brushed Speed Controller and runs fine both at 2s and 3s LiPo. Consider smaller wheels (<8cmOD) at 3s unless you are a confident driver at faster speeds.
Brushless Beetleweight Drives
Suitable for brushless planetary drives:
This mounts to the DYS BE1806 without any modification, allowing you to create a planetary brushless drive for epic power to weight ratios!!
Weight is +-67g
Warning: All screws are held in with locktight and may thread before breaking free to remove. Be carefull!! eg:

3d Printed mounts.
These are made to be printed, and are symmetrical. Print two halves and bolt around the motor to clamp and hold in place. Three holes mean two halves can bolt together leaving spare holes for bolting/ screwing the assembly to something else eg the chassis. Available here – https://www.thingiverse.com/thing:3159891
