I did not twist the timing to max to see if there was a mechanical limit.... there might be. Like I said, I only ran the motor 3 times at different timed locations with the same roll out. I never got an indication that it was going to run hot or be finicky. This could be the best motor since the Duo1, but I don't know if it's going to be better. I wont get to test 17.5 for some time now.
