What can I say? I push my equipment to its limits, whether intentionally or not.

bdebde is right. Of all of the controllers I've gone through, the only one that goes beyond what it says it will is the MM. It is a SOLID 4S controller. The only thing that my MM won't do that my $250+ Quark will is run a four pole motor. If the Lehner motors were more readily available, I would never have bought either the Compro or the Quark.

The only real advise that I can give relative to the MM is this. If you overgear the MM it will manifest its displeasure in the form of cogging. The higher voltage you are running, the more dangerous the cogging is to your esc. If you are running 5S and it cogs, get off of the throttle quick and then back off a tooth or two on the pinion.

To be truthful, when the Lehners are back up for sale I'll probably be putting my Quark/Neu combo up for sale.
