How is it we do not have as of yet an octocopter capable of inverted flight?

seems simple from the mechanical perspective, one rotor up, one rotor down and so on around the "circle".

is it that the software would be too cost prohibitive? Or that this just isn't possible.

regardless I think equal forces, half providing lift and the other half providing negative lift, would make for a more stable platform.

Or, does this already exist? If anyone knows could you post a link

Thanks

Possible I suppose but how efficient?
You wouldn't want some pushing up and some down at the same time. Lot of churning for nothing.
You also wouldn't want one set doing nothing...carrying weight for nothing.

There are a few CP multi-copters out there.

They're all DIY's and only a couple that I know of have hovered inverted successfully.

I stumbled on them in my quad project.

This one is not inverted yet but it is airborne.

There's a couple videos on YT with inverted stuff.

There's one on RCG with 4 Trex 600 tail booms.

so your saying, if I understand your enthusiasm...

you could have a single motor, powering however many "legs" 4, 5, 6, 10 etc, if we adopt a trex boom-tt-tail-rotor style leg.

with individual servos as control per leg?

WHEN DO WE START!

The concept of having multiple small rotor discs powered by a single central motor, with each disc having its own collective pitch control, allowing for a simple yet fully 3D capable quad, hex or octo machine, is already under development by a company here in the U.S. (probably others as well I'd bet).

I'm not sure they'd want me plastering their name all over the Forum at this point (I'll leave that to them...but chances are you've heard of them if you're in the heli hobby). But I've seen in person some of their concept machines. This whole type of aerial machine is still in its infancy, but it's likely to explode once the bugs get worked out.

I'm not sure how you'd keep orientation on such a machine doing 3D however (-: Kyle has flown AP professionally for a media company using a Quadrocopter's "Hexacopter XL", and even just flying straight and level, once the machine gets very far away, if the machine didn't have GPS with altitude and position hold, and an autonomous "come home" ability, it would be practically impossible to operate safely...of course we're talking on a professional basis carrying some very expensive equipment on-board (not to mention the machine itself is very costly), flying high and at long distances sometimes, and people paying money expecting results involved.

But for "fun" with little at risk, trying 3D with one might be worth a few seconds of excitement---ha!!

THANKS!

all the people are in place! Machinist...check, welder (??why might you ask?? look below)...check, just secured the programmer, he's up for the job...check, crazy guy (me)...I waiting to hear back from myself, I haven't returned my phone calls yet, I hope I haven't pissed myself off

so the project will start this winter, but...there is a twist none of you know about yet

I promised to let someone else unveil it's secret, so...sorry, but you have to remain in suspense for now

NO...

it's going to be a collective pitch, 3D capable, haven't-decided-yet quad or octo copter

with, of course a secret I cannot divulge as of yet

but you know me, I always have tricks up my sleeve.

We all don't get to go south, and hang with Bert and Bobby all winter long...

I gotta have something to do when the snow is 3 feet deep
