ZTW Mantis 45A SBEC G2 Series ESC for Airplanes

Ztw mantis 45a 32-bit ESC

I purchased two of the Mantis 32-bit ESC. Both ESC would not program properly. The tones do not match the program manual so you don't know which program setting you are in. So I purchased the programming card, that was also useless, card said ESC cannot connect. Using a 6S LiPo battery, the number of beeps should six, the ESC will only be five times, sometimes it'll beep only four times and even only two times on a 6S lipo. ZTW mantis 32-bit is total garbage, what a waste of money.
