Review: Perfect motor upgrade for my rc boat. Can't wait to install it and rip up the Lake with this beastly motor. I did a mock up and the size is just right. Motor is sturdy and strong, well built with 4 poles and a water cooled heatsink. Overall really nice and powerful rc boat motor.
Review: This is by far the largest BLDC motor I own. I build model RC machines, including boats and this motor will be perfect for my larger builds. I tested this with a 40mm prop on a 3s pack and it performed well. The included water cooling jacket is a nice bonus and even comes with spare O-Rings. Be sure to use at the very least an 80a ESC, preferably 100a+ with this motor. I'm running an 80a ESC, which should be fine as long as I don't WOT this motor for extended periods.
