OCTA-V vs traditional OCTA for AP
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.)

you right 10'' with 12" the frame will be longer than 1 Meter

There is no secret !!!!!!!!!!
with the OCTA V you have a large sight for front camera !!!
and everything is above :) so naturally protected. good for expensive camera

what do you mean ?
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

Hi, this is a video of a well tuned Octa V copter for commercial AP by Skylens UK

Hello
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.

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.

There wil be a Yaw/Pan turntable in the near future for the CarbonCore camera mounts.
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.

Hi ARHEXA,
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.
