im not too sure but i was pretty sure yesterday when i tested my boat in the pool to make sure direction was correct and wired correctly of course and thought it reversed for me, maybe im trippin haha, but today i went to try it after doin some more sealing work and no reverse for sure. now in the instruction manual i see nothin about reverse, you would think that this esc for a boat would have reverse, anybodies help would be greatly appreciated. so just tell me if im wrong or right trippin or thinkin properly, does the cheep cheep birdie got reverse?

so if this is a boat esc, i assume it has reverse??????? but maybe it does not because it does not say in description believe it or not.

I was running a 36mm 2600kv Motor on 2cell 50c. ESC only lasted 5min before it exploded in two big puffs of smoke. 70amp should have been enough.. I think this ESC isn't correctly waterproofed. The heat peals up the sealant (you can see this happen on the wires near the chip board when you solder on the plugs). Fun while it lasted.... *******

I seal all my ESC'S with a coat of electrical silicone spray and bog them with a clear water sealant before using them. I have had no problems. Cheers

Terrible speed control once you try it with a battery and a 11.1volt 3660SL 3180kv Brushless Motor Inrynner began to emit smoke
 Bazzanz 74 points
2 things could have happened to make your motor emit smoke. 1 / Prop was to big. 2/ A 3180kv motor will draw at least 64 amps and beyond. Rule number one when choosing a ESC. Lower the motor kv rating lower the amp on esc required. Higher the motor KV higher the esc amp required. But at the end of the day what you pay for is what you get.

hello. We did not put it in water, just try it to see if it works
 Bazzanz 74 points
In that case the amperage of the ESC was not enough as running under no load you need to do it for less than a minute and not at full throttle. I would check all your cables to check if they are correctly soldered. A power circuit sounds like what the problem maybe. When choosing a ESC I add 30% of amp of what the motor draws. I.e Motor draws 60amps then you need at least 90amp ESC. Cheers

that can Ι* tell you will find an excuse to tell me that I did something wrong so better not to chit chat
 Bazzanz 74 points
Was not giving excuses. Merely trying to be helpful and to set you up on the right equipment. If you don,t want chit-chat then don't submit it in this column.

I am running this ESC on 6s Turnigy 5000 20c in a surge crusher spinning a x438 prop. The boat is too fast and the ESC is perfect so far.

This esc suck , fried on the very 3rd run only. And the cooling is far too lousy. Not worth the money at all.
