Brake issue

[Patrick]

Does it do only do it if you go - brake-neutral-brake again while the car is still rolling. When mine was on the same reverse setting as yours, if I did that, it would slam it into reverse while still moving.

If it does it while rolling in neutral, I don't know what it would be, unless you have drag brake set, the throttle trim is out, or you have a very small neutral point (if that's what it's called) set and any small movement of the trigger towards brake is enough to tell it to brake/reverse.

What does the Neu 1700kv seem like on 4s? I'm thinking about getting a Neu and/or lipos for my e-maxx, but haven't made my mind up about which motor and how many cells.
