30A ESC

So when I first tried to use these they wouldn't work at all. My main problem turned out to be not having a common ground because I had different power sources for my Arduino controller and the ESC's/Motors. They all work great and don't seem to have any heating issues yet. Used with 935kv motors and 3S battery, working well so far FOR CALLIBRATING: 1. Have motor/reciever sending data 2. Throttle up to full 3. Power the ESC/Motor 3. You should hear 3 D's (means getting power) followed by 1 D (means getting HIGH signal) 4. Lower throttle to the minimum 5. You should hear 2 D's -- after that you should be good to throttle up

I initially left a bad review, because after connecting this to an Arduino and trying to activate a motor with a basic servo sketch, it did nothing other than make the ESC beep. Then I did some more research and learned these ESCs have a startup routine needed to "arm" them, AND that I needed to power cycle the ESC after each Arduino update. After doing both of those, then my servo sketch worked.

i BOUGHT THE FOUR SET AND NOW ONLY HAVE ONE THAT WORKS THE SPEED CONTROL GOS OUT AND THE PLANE COMES DOWN TWO THAT ARE WASTED AND ONE GLIDED IN NOT WORTH THE MONEY.

this esc works exactly as i expected

I received my four ESC and they might or might not work. I ordered them because I need a brake setting for folding props. I'm perfectly fine with programming them with my transmitter using a series of beeps and throttle movements. I'm also perfectly fine programming them with a programming card. But, there are no instructions included with these ESC. "Ok", I think, "I'll just go to their website". Nope, no instructions there either. So, I think, "Well, this is just Simon K firmware, I should be able to do a quick internet search." Nope, as you can guess, the instructions are based on the version of the firmware you're using. Now, I could go out to the shop and fiddle around with these ESCs and ultimately hack my way through the process. But, it's RIDICULOUS that I have to. These are being shipped back ASAP and I'm going to order some better supported ESCs. And by the way, if you're answering questions about Amazon products - such as whether or not they come with instructions or how to program them, please stop answering incorrectly!

I got these escs for flitefest combat expecting them to be damaged during use. upon first powering them I noticed after only 30 seconds of being powered up (not even throttling them up) they were getting really hot to the touch, I unplugged them and let them cool down then calibrated them thinking that might solve the issue. well it didnt. I decided to fly them anyway (I was not worried about crashing a plane meant to go in combat anyway) and to my surprise I did not burst into flames and they landed even cooler than they were on take off. I noticed that the escs were set with high drag brake (motors are stopped when throttled down) I think the over heating issue comes from that drag brake not deactivating when the motors are sitting idle. I would only recommend these escs for use on planes/projects you dont care about I could see an inexperienced person getting these and burning something up. please buy with caution and keep good air flow over them they get hot when idle.

Good power source.

These are bigger than I expected but they will work fine

schnelle Lieferung, alles OK, Danke

I am going to go out on a limb and say these are highly over rated in the actual amps they can handle.

funktioniert und kam früher als angegeben

They seem to work ok, however, one unit was dead on arrival.
