Well, I've done the go fast type BL, but for the first time I'm experimenting with what I guess you could call "go slow" BL.......in a crawler of course. I picked up a KMS 2814/08 outrunner from Hobby People earlier in the week, and finally got to drive it today.

I chose this motor because of the 540 bolt pattern, but the only problem with fitting it was the 4mm shaft, we got around that with some supplies at the store. A friend figured out that 5/32" brass tubing is essentially 3.96mm, close enough to fit the bearings snugly. To use "normal" pinions, I slid some 1/8" stainless steel rod inside the tubing, and later added JB Weld to keep them together as one piece. To hold the shaft in, I made a flat spot for the endbell's set screw, and just used the pinion to hold the other side in (it doesn't bind at all).

After driving it on 3s A123(paired with a Mamba Max esc I had laying around), I'm hooked. Wheel speed is about the same as it was, but low throttle is silky smooth, with tons of torque too. I really like it, but will be sure to beat it up a little just to see how it'll hold up before I fully stand behind it.
