Well this is the first time I have evidence of the H single motor failure mode.
Notice the opposite prop???
Notice the opposite prop???
Seems like it still handles very nicely on 5 motors.
Trent from Yuneec had mentioned in a video back in January (or February) that when the Typhoon H is running on 5 motors, the 5 motor will spin the prop 3 times clockwise, then 3 times counter clockwise. There are still some people (mostly on the RCGroups) who believe this to be fiction, however, so far the videos of the Typhoon-H running on 5 motors always show the 5th motor (the one opposite the motor not working) to be spinning in a start/stop fashion... as in this video and others. So it seems very likely that it could very well be the case as per Trent's explanation.
