Electricals/ drive system help (sorry!)

[duff]

Do you mean you want to use these for drive? Because that won't work. That controller is not reversible, so you're ok as long as you don't want to go backwards. I don't think there's any reversible brushless controllers suitable for our purposes.

If it's for a weapon then you're a bit borderline. HK recommends a 100A speedo, so an 85A one may struggle. Also, if you have two of them, that's 100A, which is more than the battery can give (5000mah x 25C = 125A. not enough to power two motors).

Edit: Oops, just saw in the thread title that it is for a drive system. So no, it won't work.
