Review: High quality, durable,easy to program, great value and fast shipping 👌🦾💯 - 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
Review: Very good esc - 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.

### ⭐⭐⭐⭐⭐ Great Customer Service!!
*by R***. on July 12, 2023*

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.
