This thread would probably qualify as one of those multiple postings you were reprimanded for. It doesn't make a lot of sense to start a new thread, make a couple of comments then move on and create another thread. It would be more helpful just continuing the comments on the end of your "Shafted..." thread and keeping all the comments together.
I don't recall reading anything in your previous thread (which I can't find now) about all four motors being damaged by the plastic threads from your aftermarket props. I don't see how that could happen. Are you sure the damage wasn't as a result of the impact?
Diagnosis of my drone....
According to the damage assessment from the engineers, it used wrong prop screw size on the drone which damaged all 4 motors.
This would be like buying a new car, buying aftermarket tires, the engine blows and the warranty does not cover manufacturers warranty. This is asinine.
Your analogy doesn't really work. It is more like you bought a new car, your aftermarket tyres blew out, yet you expect the car manufacturer to be responsible for the crash caused by the tyres, something completely out of their control. If anything, the engine blew as a result of the crash which was as a result of the tyres failing. DJI warranty their aircraft, construction and components. All of the things they were responsible for worked. They didn't have a failure with any of their components. Your incident resulted in a loss of flight. Unless you can prove something happened to a motor or controller that DJI are responsible for, it is your responsibility and that of the prop manufacturer for that loss of flight. It may be your fault for not fastening them properly or insufficiently tight, leading to a prop being thrown, or it may have been a failure of the prop itself, or an inability to grip the motor thread properly under the rated torque. The error message means the prop is not spinning at the expected speed (not that there is a gremlin on the wing holding the prop and preventing it from rotating). The unexpected reported speed is usually caused by a loose prop or physical debris in the motor. As it flew properly prior to your incident, I'd say it was the latter. The prop reviews posted on Amazon don't look too complimentary. I'm not sure why you would be surprised when DJI wouldn't take responsibility for the failure. They know how their genuine props perform, but why would they take responsibility for the pethora of manufacturers making knock-off copies and clones of their product from unknown materials and quality of workmanship?
I'm genuinely sorry or your loss, but you aren't going to change any of our opinions, especially DJ's. The very best you can hope for is to approach it from another angle and analyse your flight records and see if there is a failure of their components prior to the loss of flight. I would say DJI have already done that and seen no failure, and attributed the fall to the third-party props. |
