Nice looking product and a great price but low voltage cuts off power without warning in the middle of lake so you better have a rescue boat or be ready to go swimin! Instructions were a challenge fer this amercan... Does anyone understand how to reprogram this item for 3cell lipos so that power is reduced when battery reaches voltage that requires recharging. Turnigy 60 ESC marine is a better buy has motor cap plugs preinstalled.

Very good ESC, poorly translated manual. To configure it, push your gun radio turned on a reverse not to the neutral (push forward , connect the battery to your ESC, after the beep-beep_beep-beep_beep-beep, push to reverse (not neutral)wait beep and return to neutral)

Excellent and solid build quality. The ESC works fine and makes sure you do not overload your battery. The throttle curve is smooth and it provides plenty of power. From what I can tell, it is water tight, but I'll still liquid-tape all wires just to be double safe. After a long run at various speeds it is just a little warm, not hot. It use it in a converted HBX Wildseeker with this motor: 3900-2848SL 2848SL 3900kv Brushless Inrunner (WaterCooled). Downsides: It smells a bit toxic, and the manual is written in horrible "english". Still very recommended!

ordered one of these to try in my custom fiberglass rc surfers. Suits my application perfect.

The esc is surprisingly built really well. The esc IS ACTUALLY WATERPROOF from the get go with nice big watercooler and sealed ends.

I am running 4s ,1800kv hobbyking 3665 and 37mm prop and the esc is coming back cool every time.

thumbs up from me. thank you
