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

Excelente

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.

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.

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!

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.
