Had a major crash yesterday on my hex. Lots of carnage and smoke! Now if I only knew what went wrong.... Thoughts?


I haven't fired up my Naza again - if it comes to life, think I should still use it?

Now that is a dramatic crash video, especially the smoke at the end. I'll guess it was a broken / missing motor retaining ring.

my f550 did the same thing stupid cheapo motors they couldn't of used a smaller or cheaper clip and of course it broke in flight and same thing. Splat... just mine came down slower allot less weight on it.

It will sorta do that wobble if the gains were very low, like you entered 10 instead of 100. A loose prop nut? Bad esc or power distribution wiring/solder joint is possible too.

it got rad..... thanks for sharing

you could hear something wrong when it lifted off, oscilations like that are never a good idea to let a rig get into, the no control, well that sucks, it ate itself or whatever.

I personaly would not fly it again, based on it's buggy. was this a earlier flight in it's career or did it have alot of good flights prior?

I normally wouldn't continue flight with these oscillations but I climbed up over that tree a bit faster than I would have liked. When it leveled out briefly I thought it may be good but then well, you see what happened.

It wasn't a maiden. I previously had really solid flights with the same upgraded config. Before upgrading motors and adding aluminum arms, it was all stock F550. Had stable flights just over 12 minutes. Got the following pic just a week or so ago...

Kloner, I notice some other posts where you mention insane flight times you get. What rig? Can you share specifics on your setup?

Mr take no prisoners!
So what motors are these?

I have seen and know of many NTM motors to lose circlips and do not use or recommend cheap nasty motors any more, you can of course lose a circlip on an expensive motor but with better quality circlips it is less likely.

I do check as part of my preflight checks that every motor has a circlip, you can actually fly with no circlip until the bearing falls out and the either case ejects as in your flight or it gets a bad wobble and causes the FCU to go totally bananas.

Cheers

Pete

Probably with Aerial Mob arms and bigger motors, lots of good info on the Team BlackSheep part of the forum at FPV Lab.

The circlip must have come off even before you took off. Thats why the motor and prop flew off. The unstable flight is because as the motors rev up or down the bell housing on the motor without the circlip will have been moving up and down the motor assembly depending on how much power was applied to the motor.

I would bet that your NAZA will be fine. The unpredictable flight was simply the bell housing moving up and down on the motor and the NAZA was trying to correct for this.
I have had flights with a circlip missing from a motor and it causes all sorts of weird flight effects.
