Hi Aaron,

Those HK motors seemed the closest to what I wanted and a logical step up from the 540 sized motors in Mr Mangle. I don't think they will get too hot if geared right - the 540 motors got pretty hot on the bench test but not so much in the arena. The other plus with the sealed inrunners is that the dirt stays on the outside.

Its obvious that both types of motors have their strong points; what we really need is for you and Steve to make an external sensor board for the NTM 35 or 42 series motors . That would tip the advantage solidly over to outrunners.
