AP Hexa or Octo? What gives you the best stabilisation?

Voguna · Jan 30, 2011, 11:04 AM

Hey.

I am sick and tired of my T-rex 600 ESP AP platform. Its to hard to get rid of the vibes! I think I want to take the Aerial footage to a hexa or octo. I hope you can give me a hint of what is a good hexa or octo to carry a DSLR camera, like Nikon D90. Thanks!

They are both very stable.

With 6 motors you will crash 2/3 of the time with a motor or ESC failure. With 8 motors you will not crash with a failure and it will fly very well.

The more motors the larger the vibration problem. For AP you need to balance the motors and props to minimize vibration. Also materials make a difference. Carbon fiber transmits vibration much more than fiberglass (G10) or wood.

It seems to me that most people are building symetrical shaped quads or hexa or octo. I see a UK firm has got a different configuration which maximises the view for its cameras.

Thanks for the link, its a shame I dont understand German.
Would this configuration require different control boards than the ones many are using on these forums?

Here is a video of my UAVX Octo losing a motor in flight.
