Flight on a 29mm CTI H170. Flew to 659 feet with a peak velocity of 127 mph and acceleration to 21G. That's from the AltimeterTwo that I got to work this time. In case you're scoring at home, that's within 22 ft and 13 mph of the prediction by the Madcow app, which comes in very handy in the field when confronted with a motor selection you didn't anticipate.
