KINGMODELDual Way Bidirectional Brushed 5Ax2 PRO ESC 2S-6S LiPo Esc Speed Controller for RC Boat Tank 130 180 380 390 High Current Brush Motor Model Spare Parts

Does not work China trash.Does not matter when you set start points right it refuses do do anything but run 1 second at a time.I now have to find a third esc for this project and it’s really getting on my nerves.Stop marketing junk as good products!

Like most off-brand ESCs, they can overheat when bench testing without a load. Most name-brand ESCs don't have this issue, but as long as you're aware of this it should work fine. I believe motors need to be hooked up for it to function properly. And just powering an Rx through the BEC is not enough. I suppose the step down regulator overheats if not enough power is being consumed.So it'll take longer to overheat the ESC on a 2S than a 6S. Basically, plug up all your peripherals (ie motors, Rx, servos, etc), do a throttle range calibration, and then feel the ESCs temperature. If you must bench test for awhile consider blowing a fan on it. If it's intended to be used in an enclosed space you might consider installing an electric fan, heat sink, or cooling system. For aircraft this is often accomplished with air ports. Sort of a passive cooling system, at least while it's flying.It typically will heat up when the craft is not moving. The higher the voltage, the faster it heats up. It's lame, but appears to be the price we pay for cheap electronics. It's also risky as it's not an UBEC or SBEC so if the ESC has a meltdown it will kill power to your Rx. That could have catastrophic consequences. Again, bench test and monitor temperature. If it increases exponentially you're driving too much voltage into a cheap ESC. Go with a smaller cell battery. That or throttle up the entire time to consume the power. Otherwise that unconsumed energy is released as heat.What I like about this ESC is the dual motor with leads (JST) already attached. They can be set to mix for differential thrust, dual boat props, or tracked vehicles. Or not mixed for seperate individual motor control. This is a setting on the ESC, but could also be accomplished via software in your Tx (ie OpenTx). I also like that it's a reversing ESC. That lone JST plug (yellow wire) is the signal line for this feature. Hook it to an empty channel assigned to a momentary switch and enjoy.What I don't like, aside from the cheapness of electronics and lack of heat dissipation, is that it's for brushed motors and has a JST vs XT power connector. But that's just a personal nitpick really.

I have looking for a small, dual brushed motor speed controller that can handle more than 2 amps for a while. This board looked promising. It came pre soldered with 8 inch leads for the motors, and about 5 inch leads for the battery and receiver signal wires. It has a hefty heat sink on the board and a large capacitor across the battery terminals. The battery and the motor leads terminated in JST connectors. It has a red and green LED on board. It has a small switch to changes modes from mix and no mix. The green light lit up when in mixing mode. The overall dimensions of the board was 2 inches long by 1 inch wide. It has a BEC and was able to power my receiver with no problem.I hooked it up to a drill motor that ran at about 3-4 amps with no load. I began testing with a 2S battery and worked up to a 5S battery. i had been testing for about 5 minutes when it shorted out. I could smell electrical smoke and it was hot to the touch. I tried plugging it in again with no motors attached, and my amp meter showed it was consuming almost 3 amps of current with nothing hooked up to it.
