Trying to set one of these up with a NTM Prop Drive Series 35-30A 1400kv motor. Having problems with jitter on the motor when going steady 0-50% throttle. The motor will also go full throttle for 5sec even when throttle input dropped to zero!!! Tried changing all the settings (timing and freq) but still has the same issue. Anyone have any ideas?

I use this ESC, too on a NTM motor and have similar porplems. The motor jitters a time before starting to turn. Seems to be a problem of this ESC. Best idea is, change ESC to turnigy plush or better, to a hobbywing one. I am still using mine, but will change also before next season.

Tested it on another motor and still the same problem. Tried another ESC on both motors and worked fine. Think I have got a dodgy one, in process of RMA. May get another one by Feb....

Hello, I have had several successful flights with this 55amp ESC with UBEC. When I was plugging the UBEC output back into the receiver after some maintenance, I heard a pop, and all of the sudden the UBEC reads an output of 13.1V instead of the 5V that it is supposed to output. Has anyone else experienced this issue?

This is my first ESC and so far I'm very pleased with it ! I run it with a H2212-6T 3200 kv outrunner and I had to change the timing to high. Didn't bought the programming card so I had to use the transmitter and in fact, it's really easy. You just have to follow the tunes by looking at the instructions.

I use this on my Cx 450 and it was a simple plug and go .
The default settings are perfect for heli . Very smooth start up and a lot better than the stock Cx esc and I will be getting another for my next 450 build
