Hi Eric,
Your new clamp design, a la Marcham is truly a great way to do it, just, I suspect, considerably heaver then you’d like. I definitely like the looks of this design, but you might consider just a slight flat on the the rods, and then tie-wrapping them in place? Not as elegant looking, to be sure, but I’d bet considerably lighter! Just a thought.

I need something that is very strong… !
Don’t think zip tie will do the trick. Weight is not a big concern. 
But thaks
So what do you currently have that flys? There have been many projects designed in the past that look great, but the practical laws of physics turned them into static models. Your design shows thick materials and heavy fastners that would work for something on the ground, but not good design for something that is expected to fly. Just a reality check.
… With 6 motors that develop a lot of thrust…
That one can lift a DSLR camera… so NO… weight is not a problem … LOL
I have already my G10-Quad that fly realy good… smaller with small motors.

Sorry no good picture with motor and electronics…
BTW:
0.094" is not that thick
4-40 screws are not that heavy
Very first flight… !
Now more stable and i can fly it better…
July 24?

Yes Alan,
That was my first try as i said…
I just didn’t make any other video yet… I think i will today.
Just need someone to record, and most of the time i play with them when i am alone… LOL
Are you using, or do you plan to use GPS or altimeter feedback so you can direct it to a specific location in 3D space?
Very cool. I want one. 
The guy who cut it for me use 0.094in G10 material.
He said that his thiner g10 plate are uneven in thickness. That’s why we use that one.
Would like to try something esle… (Like carbon fiber 1.5mm)
It does take a full 12 x 24 sheet for a complete frame
I have use Aluminum standoff to attach the top and botom plate (Real light weight)
Also use 4-40 lynxmotion screw that come in 100pc bag…
I am assembling the Y4 setup today.
I have changed the Propeller since that video. Bigger that better suited to that motor.
8min at first and now 13min and more power… LOL
Oh… and btw i have change the version 2 time since that video… LOL
Now on V1.7:
Motors can be mount inside the frame and only prop is outside.
Changed the layout 45deg on the center plate to have the battery in the right angle.
Lighter frame (Cutout in the frame everywhere changed)
Nylon and even aluminum 4-40 hardware are much lighter than steel. Anything that flies deserves the lightest construction materials and weight reduction design that still has the required strength. This puts the minimum load on the motors and provides the longest flight times. The design is certainly done with weight savings in mind BTW, and it’s beautiful.
Oh… and i have already try Nylon screw. Not enough force can be put to them.
12" x 24"… I could cut it on my laser… Maybe polycarbonate? Balsa wood? lol
Witch tickness your’t thinking with polycarbonate ?
Plywood that use for RC plane would be a good idea too.
I have 3mm and 1.5mm. 3mm is overkill but 1.5mm might be flimsy. Don’t have much balsa, just mentioning things the laser can cut.
3mm is good i think… Don’t know if it will cut on weight agains the G10
Just maiden the Y4 configuration.

First flight… indoor… !
In home built aircraft construction often high strength epoxy is used for bonding parts together, with any excess epoxy removed when the parts are placed together. Fastners are used to provide alignment and clamping force until the epoxy sets, at which time the fastners are removed for weight saving.
That is honestly too cool!
