I was already crazy...DIYDRONES made it worst ! The story...part 1
My friend is a senior aerospace engineer at the aircraft certification division of Transport Canada and I am an aircraft maintenance engineer working also for Transport Canada as a civil aviation safety inspector.
That day, I challenged him into a project and he said with a smile; I hate you !
Since then, according to our wives, we are crazier then ever. We are now obsessed into accumulating enough honey-do list points to buy free time to go forward with our project.
I posted here a few pictures to tease your curiosity. If you want to play with me until the end you will get the complete story and details about what we created. All because of what DIYDRONES put in our heads.
We are planning to give most of it to the open sources community.
br/>For me it started by looking and drawing on an autocad 2009 computer screen. Did I mentioned also self learning how to use autocad?
One of my neighbor, also a friend, bought from China, on Ebay, a $1500.00 CNC machine knowing that I would learn how to use it and then teach him. Sure... but before I had to put together a computer powerful enough from some of the junk found in my garage. Could not wait to find a case for it.
After going through a few online tutorials (or was it a lot?) about Mach 3 CNC software, Sheetcam CAM software, stepper motors and controllers, etc. I ended up with my case less computer showing this screen;
and a noisy set up doing that; At least that is what my neighbors complains at 3 o'clock in the morning, you know ! CNC, router and vacuum noises.
Realizing that honey-do points are very hard to accumulate, we decided to start with cheap and easily available trex rc helicopter parts and built around it. Also we had the wisdom to start with a mock-up made with acrylic instead of wasting some very exotic and expensive material like carbon fiber. I think they call that the learning curve.
But what is that gizmo?
The continuation of our story will be by acclamation from you guys or it will die with this post...
Are you curious? Did DIYDRONES made you crazier to? Maybe we should consider a class action for it to stop...
Cheers!

I just spent far too long writing an explanation for what I saw here only to get to the end and realise it contradicted the photos. While I have a general idea (I think) I cant fathom how it all comes together. Fascinated!

It's a UFO, bottom and top disks will spin different directions. So it's a coaxial ufo :)

i stick to suggesting, that it is multi propeller arrangement, with co-axial drives and differential pitch control. engineeringOD

The last 2 photos you posted look like the large cogs are different. In the first photo they are blue and white, in the second photo (apparently displaying the opposite side) the 2 cogs can be seen through the holes and both appear to be blue.
I'd like to see the opposite side of the second photo, the photo that's using 2 blue cogs. Perhaps its nothing, but the apparent "swap" might be telling ; )

The roller bearings are meant to allow the top half to rotate against a bottom half (unseen).
They won't however because they aren't radial.
Earlier, I thought they allowed twist, but now I see they want to roll fast, given their placement, I can't see how they be useful, move them or surprise me.

Great work even if it is still not completely clear what it is going to be. One thing that really intrigues me is why you made the support for the 4 central cogs split into four different quadrants? Is there some significance to this or was it just to have some tolerance between the 4 mounts ?
Cannot wait to see the end results.

Looking at those eight sets of tubing covered bearings on axels, it appears that a rod or cylinder might rest and rotate on and between each pair of these things. For what purpose, though, I have no idea.

Duh, it's where the arms of the quad will rest. Tubular arms will rotate to change propeller direction. Is this making any sense?

Belts will run through these tubes to drive the propellers.
