Thank you Martin, your frequent builds are a very useful resource... keep it up. Owen
I guess you really mean a 4822-390kv. I did some work with timing tweaks (and had Simon add the offset parameter) some while back. I have written some notes and...
Someone mention me? Looking at your graphic Simon, and having applied my mind recently to FSK demodulation using a comparator... the same problem arises of trying to detect the zero...

Hi Simon, Let my just try a simulation of a ramp with noise superimposed, and I can configure the S/N ratio. I can try some algorithms on the delayed detector...
Mase007: I recently tested a HK 9261000003 40A ESC with latest SimonK on a 4822-690KV and got somewhat similar behaviour to yours. The motor got very hot... be careful sustaining...
