I recently bought a used Notorious 6s used. It ran great for a while and now it wont drive and the steering just twitches. I took it to a hobby shop and they tested it and concluded the esc was bad, so I ordered another one. It still doesn't work with the new one and the esc is giving me the same blinking sequence as before. Its a green light blinking 4 fast 6 steady flashes then 1 flash. Immediately after the last single flash the throttle will work for a second, then it stops again. I tried resetting the esc and re binding the receiver. I just figured out that if I unplug the steering servo from the receiver the throttle works great, as soon as I plug it back in same thing. Steering barely works and the servo is twitchy and no throttle. Is my servo bad or in something shorting out in the receiver?
