Hi,
I need advice on what airframe to choose for Aerial photography Octa.
It will be carrying about 2.5-3.5 KG payload of gear
What are your inputs on OCTA-V versus traditional OCTA (spider shape) ?
I haven't seen many OCTA-V projects, but one is impressing.
how does it behaves being a-symmetrical, compared to a symmetrical spider-OCTA ?
doesn't the V-octa have also a-symmetrical response ? (faster response on pitch than on roll, i.e.)

with the OCTA V you have a large sight for front camera !!!
and everything is above :) so naturally protected. good for expensive camera

mounting the camera above the frame ?
didn't think of that, but i think it still will have a much larger field of view when mounted underneath, even on OCTO V

I have a 1000mm Octo due in stock on January 15th.
Two camera mount options are available.

Is an Octo-V the type with four arms that split into V's? If so I can't see how these can respond properly to the changes in motor thrust as the inners arms will twist.

Have you seen the Octo-V-Tail setup? Similar to an Octo-V, but the V-tail arrangement gives much better yaw response.
Permalink Reply by ARHEXA on January 6, 2012 at 8:14am yes seen it,
but being mostly for yaw purpose, i'm losing the lift these 2 rotors can provide.
i need a lot of lift power...
yaw response is not THAT needed for me.

How can the V setup offer more yaw rate unless the motors tilt? This only loses lift, is more mass to move and move back, all potential problems. And if the V tail design tilts, what happens if a motor cuts?

It offers more yaw control because the two motors on the V-Tail are heavily tilted creating lots of yaw thrust. Yes, you lose some lift. If you have them tilted 30°, we're only talking about 14% loss of lift from two motors?
Yes, if one of those two vtail motors fail, you're in big trouble.

i used an OktoSL frame (which i am currently selling) from there: http://www.blaui-rc.de in form of spider, because in germany (worldwide not sure) the V-Shape is patented for commercial use. My frame had payload of 3 kg if needed even with 8 motors (36/6 Motors and 13/6.5 props) I made photos with 500D as well as with the 5D MkII
The advantage of the V-shape is a big field of view with a poor yaw function due to payload not in the middle.
Season Two of the Trust Time Trial (T3) Contest has now begun. The fourth round is an accuracy round for multicopters, which requires contestants to fly a cube. The deadline is April 14th.51 members
