Personally, i dont think we need anything bigger than an etek drive.
If you're using Dual Perms to move your bots, you're doing it wrong. If you need more power, fit another T64 in there. I've built Ultraheavyweights with about 16 T64s double stacked and they're very fast and maneuverable.
Eteks are actually too slow for me.(for my 10k Kg bots anyways)
I dislike Etek drive motors, they only face one way for me. Unless I'm an idiot and don't know how to mirror them.
Huh?what I mean is, I feel like there is no way to have a left and a right facing set of Etek drives, they are kind of like the burst snappers and other such motors, no way to reverse them for oposite direction use without making rediculously huge bots to house backwards motors.
