MMM v3 BEC questions

[BrianG]

Looks like an interesting project! You're right; the Slash is about the only stock vehicle I know of with that much empty space on it.

1: As of right now, I would say no. The BEC also supplies at least part of the ESC brains with ~6v power, so any adjustments would have to be tolerated by those other components.

2: Not sure what the current output of the built-in BEC is, but judging by the components used, I'd say around 3A is a safe bet. And since it is a switching BEC, that available amperage is good for all voltages from ~7v up to the max of 25v. BEC efficiency doesn't change all that much with supply voltage - it's the load current that makes it fluctuate. And switchers tend to be most efficient at around 75% of their max current rating from what I've seen.

As far as getting stuck in control loops, you outta put in a manual override so you can use a remote (at least for the testing phase). I can just see people running after an out-of-control Slash trying to catch it!
