Your right on- with the exception of the subject forces being inertial rather than aerodynamic.This guy spins them tight.....Im my book that's wrong....He sure should snug them down and use the Dji prop tightener took and run them tight and use the Dji tool to slightly "snug" THEM TIGHT ! After all.......IF you lose a prop in flight ...that quad will fall from the sky....when you decelerate the motors / props the props are subject to >"reversed"< aerodynamic forces that loosen them....! Correct me If i'm wrong !
Fail to snug em down and chances are good one will fly off at a very inconvenient time.
