The real problem was first "discovered" with the Inspire 1. Some Inspire pilots began reporting that propellers were flying off, crashing their $3K aircraft. After much finger pointing, mostly claiming that people were not tightening the propellers properly, DJI realized that they really were flying off. Initially that made no sense. They are self-tightening, after all. But the braking system on the motors combined with the mass of the spinning propellers were together enough to loosen and even unscrew the propellers from the motors and fall off, particularly in windy conditions or aggressive flights.
On the Inspire, DJI designed and began offering free propeller locks that you attached to each propeller. Later they came out with self locking propellers (also sent out for free to us Inspire customers) that you no longer screw on, but rather push down and turn to install. Much like child proof medicine bottles.
I've not yet received my P3P (arriving on Thursday), but I am interested in understanding what's different about screw-on P3 propellers that will make them stay on better than screw-on P2 propellers. If they both screw on with no locking mechanism, then the only thing that keeps them on is making sure you tighten them enough. Also, because the P2/P3 propellers are smaller and lighter than the Inspire propellers, maybe it's really not that much of an issue, such that either the P2 or P3 propeller should work equally well. Those of you with both a P2 and a P3 care to comment about specifically what makes a P3 propeller stay on better than a P2 propeller? |
