The plush is more advanced. I had a 20 amp brushless motor hooked up to it and it popped. It was not even at full throttle

It popped with a 20 amp motor and popped at half throttle. Is this UL safe

Hi, I have purchased one of this ESC but its not detecting the receiver the outrunner motor is not working according to throttle. Unfortunately this ESC is not beeping while switch on (connected in Receiver’*s battery port receiver’*s throttle up). So now I wanted to reprogram it please help.

If its not working at all, it may be connected to the receiver wrongly, try connecting it to the receiver the other way round.

excellent cheap ESC, exactly as described, easy to program with TX and very good throttle response. I'm using it with a 4200kv outrunner and 3s lipo with 64mm EDF, great setup!. thanks HK

Picked this up a week or so ago the unit came in perfect condition. programming was not required as it worked configured out of the bag. it would be beneficial to have a detailed spec sheet on beep config packaged w eack hk unit sold rather than hunting online or waiting for someone to post. would buy or reco again

I have bought this and receivied few days ago. It was well packed. I had 1 flight with it, and it was good. No problems occured during the flight. After flight it was barely hot. I recommend this esc, because it's possible to program, and it has good price/quality ratio. :)

Good quality and well built, pre progged from box with generic settings, but easily programmed from TX. Bang on the mark for a speed controller

It is worth spending the extra dollar or so to have the 3.5 mm connectors already on these esc's. This was money well spent and can handle the rated 30 Amps.
