Hoverfly Xocto or +octo???


Both have there advantages. I love the X8 for ease of transport and it is VERY stable. I think the Octo is visually more professional looking and gets a ton of comments on the job. I hate the fact that there is a public perception of what a pro rig should look like, but I have specifically asked people that I work for about this and they admit the Octo is more impressive looking. You won't go wrong with either one in the long run unless you have specific requirement. I jsut happen to have both.

Xpcto is different from X8...!!!!


The +octo and xocto are flat octo...!!
 

Ahh, missed that.

+ or X would not fly any differently. Not that I would be aware of. It won't really change forward visibility if that is what you are concerned with. The props end up being very close to each other all the way around. Just make sure the controller your are using supports the configuration.

I use hfp... And it supports it... So there wont be a difference??

Welcome to MultiRotorForums.com!!
they fly exactly the same. if you go with the + format you can count on that forward motor dropping down into view anytime the camera is close to being level. the x will do that too but it will be worse with the + format.

Thats not a problem for me..! the thing is the stability on the wind and th overall stability.>!

if stability in the wind is of primary importance then a coaxial quad or tri-copter would be the way to go, IMHO.

Yeah, I can blow that up.
We tested both octo and x-8 and much prefer the x-8. It flies much smoother ( in my mind anyway). We love it. As for not looking professional, well, it's not our bread and butter so I'll stick with the best tool for the job.

I don't "like" X8 or Y6 because it is my belief that it is not as efficient. I really don't see any advantages to it. However, some people have chosen a coaxial geometry and believe that it is more stable under certain conditions like wind.

So the bottom line is...we support X8 and Octos so you can choose whats best for you. I enjoy seeing the results that people are getting with the coax systems. If it works for you I am happy.

Since I am chiming in on geometries I don't "like"....I don't believe Hex is that useful. I believe its better to add two more motors and make an Octo. If you loose a motor with Hex you loose 33% of your yaw authority...with octo you only loose 25%.

As far as +Octo vs xOcto...I don't believe it matters. Your gimbal should be low enough not to see props anyways. However, most shots I've done aren't tracking very fast....so maybe for those fast moving shots xOcto would be better.

Al for me the advantage of a x8 or y6 over an octo comes down to my flying ability and my issues with orientation. I find the x8 and Y6 easier for orientation but over time as my LOS flying ability improves I know this will become less of an issue. I have this problem where my brain tricks me in to thinking my multi is tilted to one side when I have it at a distance from me. Even with various orientation aids at distance on a cloudy day this causes me problems.

Efficiency concerns are balanced by less complexity and less weight. Then there's the size of a heavy lift flat Okto compared to an X8 or an even more compact format like my XY8. There are a lot of extra hardware and airframe parts for a big flat okto that a coaxial won't need. So the efficiency argument seems plausible by itself but the other factors contribute to keep it from being a standalone basis for flat formats.

A detail that is often overlooked when it comes to camera mounts is that the lower the camera hangs the more it cantilevers when the heli pitches or rolls. As the angle of roll or pitch increases the cantilever effect increases putting a lot of stress on the mounting points and often allowing components to flex and then unflex which shows up as wobbles and movement in your video. To tuck the camera up under the heli isn't a problem provided there's a clear field of view from which to shoot. It's not a problem if you're flying the right frame. :)

how do you controll your flat 8 in wind?? thats the worst problem with multirotors..!?? Is there something you do something special?? or you dont fly with wind?
 

The day I first flew my Octo heavy lifter, the winds were gusting 25+ mph. It handled it like a champ. My smaller quad would have been all over the place. It seems like everytime I fly its very windy. Not sure I know howto fly on a calm day! If you have good isolation and a gimbal that's set up correctly you should not be afraid of the wind.

Couldnt agree more. I recently flew my Skyjib 8 in 24mph gusting 36. It just leaned into the wind more & the WKM kept it solid. The frustrating thing is that the video from it is impressively stable and it doesn't look particularly windy!!! To those that doubt, the PH Skyline really does work (after 8 months tuning :highly_amused:).

I cannot have usable video afte 10kmh wind:(:( or the machine is not great balanced onr the hfp is not as good as dji in wind:(:(
