Hobbywing XR10 PRO 1-cell ESC. I'm selling it because it's overkill for me. The capacitor is built-in. It's for 1/12 scale 1-cell use. The cable connecting to the receiver has been shortened. The crimping of the connector isn't very well done. I ran it once and then took it off. It works. Please judge the condition from the photos. Please refrain from bidding if you are a nervous person. Thank you.
