Another Wookong fail, from hot to cold problem?

[Muunk]

Last sunday I was out and flying a little fpv with my octo with wookong. At that day it was about 0 degress celcius outside, and normally I allways let octo stay outside for at least 15 min. before flying. This is what happened the day I only let it outside for 4-5 min. before takeoff.

I´m pretty sure it was because it didn´t had the time to acclamatize. :upset:

Damage report was a broken arm and gps carbon rod. Have not got time to test the motors yet.

Definitely an 8X for me. There are too many WKM flat octo's dropping like flies.

Sorry to see that, Muunk. Was the craft forcing you into the yaw spin at the end, or was that you trying to fly out of it?

I'm curious what you find when the motors are tested.

Hope you get back in the air soon.

I havent seen any octos crash apart from this one, quite the opposite in fact. Bart had a prop break on his the other day & safely landed it. I think octos are the safeest of all MR aircraft to be honest.

Bart is using MK. I cant see a difference if it works in an X8 why not a flat octo? Who knows? give me 2 of them and i will test them for you all

Well if you look at 0:23 you´ll see the first movement witch isn´t from my stick input, after that you can see that the octo is acting more and more weird. At 0:55 the return to home funktion is activated (As I remember it).
I hope that I can get some new props tomorrow at a friend, and then be able to test run the motors.

 

[Muunk]

And yes, It was me trying to force the yaw back, until the return to home funktion was active.

At 0:23 we hear a crack, and the motors make a different noise. Sound Like a broken prop? The octo compensate till motors get to hot and then the multi crash?

Well that could be possible! But why should the motors get to hot? All up weight is just under 5 kilo, and 6-7 props should easily lift that amount of weight. But on the other hand if its not a prop that breaks, why should the motors change sound like they do? hmmm... :apathy:
