So I have this Futaba FP-MC12B/MC112B

[Parish 0]

I got it in like 1987, And the instructions for this motor controller (that I still have) states it is rated for 100A Continuous Current, and 400A Instantaneous Current. 7.2V-8.4V rated, with a regulator output of 6V/2 A max. I have it in my Old Sand Scorcher, and I want to know if I need to stick to NiCads, or if I can move up to NiMH batteries. I like the idea of lots of current capacity, and have pretty much ruled out LiPo's, as they seem like I need to keep a fire hazard out of my car, and that much current will have me blowing another counter gear. I currently have my original 540 motor, with no real plans to go nuts with it, as I want to run it with out buying parts all of the time. So, what do I do? And where in the States do I get reasonably priced quality packs, or do I break out the old Weller Soldering gun and start connecting tabs, heat shrinking, and wiring my own?

NiMh packs will be fine with it.

I'd be carefull what motor you run, the Scorcher is a heavy car - not sure on the turn specs of the 112, but the later MC230 was around 21T (I think) the MC330 had a 13 turn limit.

A quick search give this though http://www.tamiyaclub.com/forum/index.php?showtopic=47581

I run the MC112B in an Astute - still not exactly a light buggy. Its couple to a 14x3 motor which is too much for it but as i only run it for 5 minutes at a time, and then rest it for 10-15 minutes,so far its survived (it gets very hot mind !).
