I have bought one of these a couple og months ago, but havent used it since yesterday. Jittre, jittre, but after a few flight, suddenly the motor span up full throttle, couldnt do anything, even switching off TX didnt stop it from spinning. Quickly switched back on. I had control of the servos, but not on the motor. finally somehow I got the plane down, but just because the prop adapter probably loosened from the vibrations and got lost. I am wondering, am I eligible for a replacement or refund or something? It wasnt a very cheap ESC and I cannot use it any more (in case I dont want to crash the plane)

Has anybody figured out how to get rid of the jitters on these or the 45Amp model? I just ordered the programming card but haven't tried it yet. Anybody?

No, you won´*t get rid of the jitters. Thats the ESC, not its settings. Only way is to use other ESC. Mine jitters at starup only, but after about 2 seconds it runs ok. The BEC on this esc ist quite good, which is the case soldom enough. But the startup jitter seems to be a genetic-defect:-)).

I had one of these and had the same problem as described below . Installed turnigy plush 60 amp and problem went away

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....

I have had the same problem with this ESC, motor jitters above 50%. Hobbyking sent me a replacement ESC and that one has jitters as well. I have ordered the Plush 60amp ESC and hope that it cures the problem. I believe the 55 amp TRUST ESC must be a POOR DESIGN.

Joining the crowd with this one...James sums it up well. Will be doing the same.

I have two of these in a twin application. One jitters the 42-40 890kv motor terribly on throttle up and will lose sync with the motor at 3/4 throttle, every time! The other one jitters slightly bit has lost sync on a quick throttle up. Not a very good or reliable product for larger, higher power motors.

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
