When I started with the Fiorotti timer, I tried a Castle ESC. It worked in the sense of powering up and flying, but the response was too slow for changing rpm, so the acceleration and deceleration were slight behind needed. It worked at a sport level, but not for competition. That is a basic problem for accelerometers. It will likely take someone trying it to find out, but my guess is that it will be too slow. On the other hand, the price is not bad for a trial.
Programming looks to be RC transmitter only at least for now. Some of the brands share programming cards, again found by trial and error. In the print, the seller say that multiple parameters can be set by remote control and then the defaults can be restored by remote control, presumably meaning RC transmitter.
