Does the props always get the first impact ?

[Isaac94]

So I'm just wondering, so far no crashes on my MA after using about 2 weeks. But just wondering, if it does crash, any crash at all ( unless it's drop down from top straight to the ground ) otherwise, all kinds of crash situation, could i say that, the very first part of the drone that will get the crash impact will always be the propellers first ? ( Or propeller guard if it's equipped ) as it is the most outer part amongst the drone ?

The most exposed parts of the drone are the props and the landinggear (if available ofcourse), so yes, the props will take the first blow of a crash. But the props are relatively soft and flexiable, so they "give in" and then the arms will take the rest of the force. I would always carefully check the arms of I would have any damage to the props.

Ahh ok, because last night I think I had a close call, I was just flying outside my house and there was power lines cable outside, and I know that of course so I flew up carefully, but then I used RTH to return my drone, it went quite close to the power lines cable but I'm very sure it did not touch it or crash to it, just quite close as I was watching very closely and later on inspect my prop but found it all perfect as it is. So that just got me thinking, it would be the prop first that would take any 1st direct hit, only then like you said, will be the arms take the rest.

Also, under low light situation, any of the obstacle sensors of the drone will not work ?

Just a note on what you discovered. The drone can’t react to wires, guy wires, clothes lines, or electric/phone/TV cables. Know the area you fly and set up your drone to avoid these “drone killers”

By can't react to, do you mean that even if the obstacle sensors are active, but it will not sense and react to wires etc ?

 

[old man mavic]

the sensors are not fool proof,they have issues detecting wires ,thin branches ect ,and as you know are not very effective in low light conditions plus not all the sensors are active in certain flight modes be aware of your surroundings at all times ,and please do not just rely on the sensors to save the day

Yes, in the majority of cases.

Don't worry! If your drone hit the cables (any cables). you will know (says the man who hit a line in his garden with his first drone...)

So sorry to hear that mate, hope your drone is all good now. Yeah I was watching it closely as it descends close to the line, but I heard nothing at all, even if the props were to hit or touch the line there would at least be some kind of sound, but none, so I'm glad !

Let's put it this way: Education never is really free of charge!

It costed me about € 50 and some nerves.

I guess nothing is ever free of charge, it's either a lesson learned the hard way, or the normal way. Glad to know it's all good now !

Olav Van Gerven hit upon an important post impact procedure that would have saved me significant damage to my M2P. Always do a thorough post "minor" impact inspection for less obvious damage. Probably good to run all the alignment procedures as well.

After dark, I slipped on icy steps and the drone went flying (without benefit of first being powered up), it came to a stop after hitting a brick wall. I did not do a thorough inspection (it was dark) and went flying anyway, with what I later concluded must have been a cracked left front arm near the hinge pivot.

In flight, from about 20 feet up, a warning said it would like to land please, I added throttle. But it soon repeated the warning. Clearly it was smarter than me, as I again advanced throttle to gain altitude and continue flying. Shortly thereafter the LF arm, which was no doubt bent upward causing the motor to run out of downward thrust authority to maintain normal flight, failed completely. There was this pinwheel effect of LED gear position lights spinning as it cartwheeled down, breaking another arm, both front arm hinges and the left rear one too.
