30A RC Brushless Motor Electric Speed Controller ESC 3A UBEC with XT60 & 3.5mm Bullet Plugs

These are awesome little brushless ESC's, really reliable, durable, easy to program and surprisingly powerful, I like to diy add my own cooling block and seal both ends with epoxy where the wires come out just to hopefully prolong the life of the ESC 🤷 high quality for a great price and fast shipping

Good controller and they have a great website which helps with all common FAQs. The weight is as expected for this size of esc. Only thing is while connecting the power to xt60 plug the contact spark does caught me off guard so watch for it. It worked great with my propeller and arduino setup. But website mentions bec is 5v but gives slightly more so don’t connect to 5V pin on arduino if you are using one connect to Vin

I very seldom write reviews but just had to for this esc. I bought it to replace the one in an electric rec helicopter that is probably 15 or more years old. All the connections matched perfectly and I had the servos all working but the motor would not spin up. You can scan the QR code on the esc and it brings up the online manual which is very detailed and easy to follow if you know what you were doing which I didn’t. I called the customer service number and actually had a person answer wasn’t press this number press that number for this or that. An actual person answer that spoke English and he was able to walk me through some troubleshooting and basic set up procedure and got everything working perfectly. He was going to send me a replacement if we couldn’t get this one working but it turned out not to be necessary. I would highly recommend this company.

I bought this and the listed programmer, to try to turn the motor speed down (I'm using it to power a rebuilt vintage blender...). Lowest speed was still about 2x what I'd wanted (note this is with belt/gear reduction already). Since BLDCs can have arbitrary speeds, not sure why there isn't a special "crawler" mode or something to this controller. For my application, I also found the cables too long, but of course that's easily rectified, and much better than too short! It's great that it provides 5.5V out, which allows me to power both the controller and the light show without requiring a separate regulator.

I have these in three of my planes and they work very well. Just keep them in the airstream and they run cool. No problems found.

Fast shipping, notifications great

Worked well for me

Emailed the company after the esc would start up a motor with no load and then stop after about a second and a half, got no response. sat around for a while, went to test it with an edf because I only had a 15 amp esc on it that would get too warm (I use it as a normal fan, not for rc). It seemed to run fine. I had it on 12v at whatever throttle net about 15 amps of draw to compare. To my surprise, the heatsink didn't seem to get warm, granted it is indoors in an air conditioned space and the esc is blown on by the edf which is an extreme amount of air. I walked away and not even a minute later I heard it slowing down so I ran back and the capacitors were all swollen and you could smell melting plastic and they were about to pop. seems like it had the potential to be a decent esc but the cheap chinese capacitors held it back

Excelente

Great

It immediately exploded the moment I plugged it into my Li-Po battery. I checked it with a multimeter and sure enough, the item is defective. The package it comes with is stapled as well.

Seems to work fine. Works on set up. Cant fly right now. To cold.

GOOD
