Strafer Chassis Kit


Currently Sold Out

The Strafer Chassis Kit is a rigid, low-profile chassis that includes high-torque 435RPM planetary motors, ball-bearing mecanum wheels and a configurable chassis you can tailor to your liking.

At a glance, you might wonder, where are the motors? Flip it over and you’ll notice the nested 5202 Series Planetary Gear Motors to create a final drive ratio of 27.4:1 after the 2:1 bevel gears; this creates a theoretical speed of 3.73'/sec'. These motors have all steel bevel gears, heavy duty hubs, and ball-bearings ready for some low-friction strafing action!

Bevel Gears
The bevel gears, located near each of the four corners of the chassis, create a 90° drive so that the motors can nest inside the 1120 Series U-Channel.  The bevels have been battle-tested, even with brushless motors, and are extremely stout.  Don’t worry about slipping as they each clamp to a 6mm d-shaft and the bores are matched to the d-profile of the shafts they mount to.  

Each 6mm d-shaft is supported in a pair of flanged bearings in order to maximize the torque transferred from the motors to the shafts.

The goBILDA Mecanum Wheels are 100mm in diameter, have ball-bearing supported rollers and allow the mounting hub to nest inside the center of the wheel for a clean and solid attachment to the shaft. These wheels are 315g each, far less than the competitors. The reduced rotating mass yields quicker acceleration with less strain on the motors.

The channel framework allows you to pack all these premium parts in without having to clad on to the outside like some frames require. And oh-so configurable - move the center channels, adjust your track-width and more all with the same parts we provide.
