CrackerBox Test Chassis

[TRUCKMAKER]

Here's a reason why I built a dedicated test chassis. I bought one of these motor/planetary drives, 437RPM @ 12v. The volt range on the motor is 6-12v so I ran it off my 7.2V battery realizing it would be a little slower. It was actually to slow however smooth and controllable. So while taking a break from other projects on the bench I started playing with some stock cans I had laying around and found that bolting this Axial 27 turn up to the planetary gives me a good top speed and plenty of power. The true test will be going to a meet and load some construction equipment on it. Surprisingly I haven't found a less expensive alternatetive to replace the 3spd with. Buying new, the 12v planetary combo is $40 & the 27t Axial is $14, just need to figure out what to do with with the extra 12v motors down the road.
