HobbyWing Seaking-120A Brushless ESC for RC Boat (Version 2.0)Calvin CheungJuly 9, 2012I have both the 60A and 120A ESCs both seem to perform better than the stock ESCs that came with my boats and seems smoother throughout the whole power band. Best bang for the buck...WAY cheaper and better performing than the stock ESCs.
HobbyWing Seaking-120A Brushless ESC for RC Boat (Version 2.0)Reno rc BoatmanMay 31, 2012This ESC is not water proof but rather water esistant. You can seal the ends up with some silcone or make sure that it is inside a water tight radio box. The number 1 reason to buy this ESC is its cost. For the features you get for the money it blows its competition out of the water. Being able to adjust the timing has made my brushless marine motors go from tame to insane. The ESC is not hard to program, just hold down the trigger and when you want to make a selection let go of the trigger and then hold the trigger down again. If you have trouble programming the ESC you can buy the program card and it will come with 3 program cards, not bad for the money. I will definately buy more of these for future boat builds....
HobbyWing Seaking-120A Brushless ESC for RC Boat (Version 2.0)ShawnMay 30, 2012Its the only brand of ESC, and I have tried many, that hasn't burned up, for no good reason. Keep it cool, and it performs very well. When it gets too warm, it reduces power, so you can bring it back to land, clean debris, or reconfigure your cooling system. I've used several different brands, with the same rating, with smaller motors, smaller amp draw, smaller rpm, and have had them burn up, repeatedly, even when using a 120a, for a 60a recommended motor. Good product, version two, and good price. I own three, and will be getting more to replace the burned up other brands.
HobbyWing Seaking-120A Brushless ESC for RC Boat (Version 2.0)ShawnMay 9, 2012Excellent. This is the first one I've purchased that lives up to it's ratings. No overheating, even after a ten minute run, which barely reached full throttle, as the performance was as advertised. I've burned up a dozen other brands both air and boat applications, and the majority of them were due to poor quality. Stay away from Detrum. Hobbywing is now my first choice.

HobbyWing Seaking-120A Brushless ESC for RC Boat (Version 2.0)Eric ChinAugust 15, 2011I have had nothing but problems with these ESC and have had 3 of them. The 1st one ran great for a few fast runs and then the boat flipped over and the ESC did not work after that. (even though it says that it is waterproof, don't count on that to be the truth. The 2nd and 3rd I got I applied silicone on both ends to waterproof them. The 2nd ESC ran good a few times and then stopped working and then the receiver stopped working! Upon checking the ESC, it fried 3 receivers and so I measured the voltage at the throttle connector at the ESC and found it to be about 16vdc where it should only be about 5-6vdc. The 3rd one I removed the silicone and shrink wrap and found it wet inside and if I ran it, it would fail soon enough. So if u buy one, make sure it is in a waterproof box and check the voltage at the throttle side connector on the ESC before u plug it into your receiver, before u power it up with your batteries.
