Hi,
I have to purchase a new combo and think I will go with Cayote ESC and motor.
Since I already have an Hobbywing combo with the BT OTA module, do you know
if I could use it with the Cayote ESC ?
My first guess would be yes, but since I'm not 100% sure I prefer to ask if anyone knows.

Why would you guess yes? I'd always assume that different brands aren't compatible until proven otherwise.

First because I'm not sure they are anything else than interfaces and second because Cayote seems to be some kind of Hobbywing copycat

i wont think so. imagine you are the manufacturer and oem cayote, would you produce it interuseable?
just like old day's gm turbo esc and yokomo's and the r1,.......

having said that, i am excited to learn after you. thanks

Sure. I'll give it a try as soon as I get my hands on it.
I saw a video even the default BT cia the same as HW. 888888

As anyone try the HW ÔTA on the Cayote crest x?
