I have just received a Deans Marine kit, ST441, a seaplane tender. The plan calls for a Black400 motor with a Bob's board and 6v battery. I would like to use a brushless motor and ESC in the kit. Deans say they have not tried the kit with a brushless motor so cannot recommend an alternative. Any one out there who can suggest what such motor would be the equivilant of the 400 motor. I have one suggestion from the Component Shop, they are always very helpful, but anyone else has any suggestion.
