Both the KH dump trk & white GL have used a Mtronic Viper Marine 15A for yrs! The green GL is using a 2x12 Sabertooth (the 2nd controller is for the hyd pump).
The Mtronics come from the UK, I tried to get some more Viper Marine 15A esc's a few yrs ago & even try their latest 20A version from Howes Hobby, but they wouldn't ship to Canada on a CC# order, insistance of a money order seemed ____? Anybody have a north american source b/c I'd like to get some more of these smoooth brushed esc's.
