This is the second flight of the Protos. For this flight, the governor is set to 2800 rpm. This seems to be a bit too much for this gearing, as you can hear it doesn't have enough overhead to maintain that headspeed at full pitch. Flight time is also much shorter (4 minutes) due to both the higher current draw and a pack that was slightly out of balance. At the end of the video I take some temperature readings of the various components.
