Mayhem ST Brushless Conversion Project

[hunter306]

Well, a couple of things worked out this evening. First, I sold the Mamba Monster Max I was planning on using for the build, I'm too nervous about failure of the controller to run it -- I think I'll wait until they really do get all of the bugs worked out before I replace the current controller. Second, the 9XL Motor is rated for 75amp continous MAX. The Monster Max was significant overkill for the job.

I swapped in an old BK/Warrior that I had laying around. It fits the build well, as I wasn't planning on doing anything but bashing around the streets of the neighborhood anyway. I still have to figure out how to program the BK, but it's current settings work fine (as evidenced below) for testing.

Ended up using an old IB4200 - 7cell pack for testing. I'm getting a TON of cogging right off the line, which I'm attributing to steep gearing and poor amp delivery from my battery pack. I may fashion another pack to use in here until I get my lithium poly.


Here are a few more images... I rough-fitted everything and took it for a test drive. Ultimately, I'd like to add a small cooling fan to that ESC and do some wire management!
