I hit the wrong button, and if I do that I can’t delete the page, so I thought I’d give a little info on the motor I’m using in my Taucher Wulf.
The Zippkits 650kv outrunner is a quality unit. It’s made for Zippkits by TFL, who is known for making motors for the fast electric crowd. This is a 36 mm outrunner designed for working boats and tugs. Lower rpm than most motors of the same size and high torque. The Springer tug that Zippkits sells weighs around 6-8 pounds, and that is what this motor was designed for. My Taucher weighs in between 14-15 pounds fully ballasted, and she was designed to run a brushed 550 fan cooled motor, something akin to the Speed 600. I get good performance and run time with this motor. I think 15 pounds or so is probably close to the upper limit for the motor. It never gets hot but it does get slightly above ambient. This motor should be a good match for anyboat that needs a slow turning torquey motor of 15 pounds or less. I’m really tickled with this motor!!
