Not yet but they aren't that expensive.
I'm happy to contribute what I can to this. For example, I've got a datalogging board that captures a bunch of stuff at 50Hz and writes it to a microSD card as it goes, so it can record practically forever (well, not really, but in RC terms, I've captured whole runs at 50Hz. Current version of the hardware captures battery voltage, motor RPM, throttle input and acceleration in 3 axes.
Sounds pretty cool and it might work for a dyno setup but the RPM needs to have a bunch of points in the first few rotations. That is why I am trying to capture on a turn by turn basis instead of a fixed sampling frequency. Can that be done with your setup?
