Thanks Bud,
I have 2 scooter motors here that I was going to use in another Tug build
But after the information from yourself and the availability of brushless, I'm going to use 1 of the scooter motors in the big tug and use Brushless twin screw setup in the other tug/ mostly for towing, the props on this tug are 70mm steerable Korts.
Thanks so much for the information.
Regards
Adam
