40A RC Brushless Motor Electric Speed Controller ESC 3A UBEC with XT60 & 3.5mm Bullet Plugs

The media could not be loaded. This little beast is by far the smallest 30A ESC, which is crazy considering it is also bidirectionalI've only had this ESC for one day and tested it briefly, but I was so impressed with it. I have about 10 regular 30A ESCs, half of those also from the same brand (rcelectricparts), they are all about 3-5 times the size of this ESC, and they are only unidirectionalIt does look a bit weird to me sometimes, as if the cables are too big for it, almost like a little kid trying on their parents clothes, but I guess nothing is perfectAnyway, very happy with this purchase so far. If it works well with my current build, this might be my goto ESC for everything I build in the future... very exciting

Delivery was quick and was easy to access the manual via the grid code. Initial hook up on a used older plane went well and seems to work well in the shop. Still have more mods to do on plane and winter to pass to get the real test. But so far so good. Happy with purchase so far.

Good old basic speed controller. Works fine right out of the package.

I am using it with ducted fan foam jet, and 4 cell lipo. So far it’s flying, doesn’t seem to overheat, but it did take me down to low power at one point. I don’t know if it’s because the lead wires are a bit skimpy. I’d say it’s a good value. If you don’t overload it . the default settings are pretty good and you really need the programming device for 10 bucks. If you wanna program it as it’s almost impossible to do from the transmitter.

Ridiculously small and functional well. This is black magic

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.

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

Just installed in my flying wing that I built myself and look forward to taking it out for a maiden next week. I have used this same ESC in other builds and have a 60 Amp in one of my larger DIY built planes. Great product works very well and if paired properly with the correct motor and prop it should work like a charm. I can say with test It does get warm but I have not had one fail on my yet. Great product!
