Quad Nightmares....

[andys]

Had the mother of all weekends.
Thanks to Neal for answering lots of questions

Built my 550 with Naza V2 & Gps - with afro esc's and Sunnysky motors + tarot Gimbal.

Checked it all over and plugged in the power .... Smoke

Quickly unplugged it - bottom board had fried. Quad totally dead.
Then I saw the problem. The power wires (HX something or other) - although red to positive / black to neg were wrong in that I should have had an opposite connector so it married up. It looked right - but was reversed

Changed it - still all dead. Tried Naza on its own and seemed ok - phew.
Voltmeter on the quad bottom distribution board showed it was dead - looks like it blew and saved the rest of the electronics.

So - as I needed to help a friend do some filming on Sunday in Sheffield I decided to put the Naza into my spare 450 frame. Got it all sorted (eventually) and it flew great with good gps lock - so I felt confident taking it to Sheffield to fly from a building roof terrace to help with my friends short film.

A few good flight at home under my belt - I set off to Sheffield.

On the filming set - I powered up and waited for warm up and green light, then went to take off. The quad flipped over straight away, smashed a carbon prop and went crazy upside down until I unplugged it. Flummoxed - I put on another prop and tried again - seemed ok and managed to film the bits for my mate.

Properly stressed with it all though.
No idea why it flipped on take off and went bonkers.

Dji 550 kit ordered to replace my burnt out Hobbyking 550.

Bloody nightmare.

Still haven't dared try 'return to home......'
