What's_nitro: An inductive clamp (which is what you're talking about) probably could be used, but I'm not sure if it would be small enough to fit without taking up too much room. In these vehicles, weight and space are at a premium, which is why these ESCs are so small/light to begin with.

kostaktinos_mt: I believe Eagletree does use the shunt resistor method. No biggie just for playing around, but I don't think I'd want anything that introduced losses into my rig. I do agree it would be nice to have something like that, but I'm sure the price would reflect the additional circuitry. The time-delay, or integration, of the punch control setting is not perfect, but sure is better than nothing. And I do agree about the clock speed of the device needing to be fast enough to measure those milli-second pulses.

Doesn't eagletree sample faster than 10X/sec? I think that's the default, but IIRC, you can speed it up but at a loss of storage room.
