Here is the frame assembled…!!
Pictures touch-up by Innerbreed… Thanks to eleminate my bath tub… lol
Your QuadCopter looks great as well!
Not the shiny aluminum, but basic black. I like it!
Carbon fiber or G10 Epoxy FiberGlass?
Alan KM6VV
I am on the way to make it cut out of Carbon fiber… !
Looks like Fiber!
I know, Kevlar!
Alan KM6VV
love the DiaLFonZo-Copter Blue Carbon! 8)
HéHé… i should have the Red one soon.
This is real carbon kevlar sheet.
found a US supplier… 
Red would be interesting, but then I have a black car…
Alan KM6VV
… LOL
Go for black CF…
A submarine quad! (testing in bathtub).
Alan KM6VV
I’m rather new to all this so of course I’ll defer, but wouldn’t a submarine quad have to have the motors reversed so the props screw it down below the surface? Also, what about waterproofing the circuitry unless the water in Qubec is so pure as to be non-conductive? 
Eric, it does look good, but isn’t that tub difficult to keep filled?
Actually, for operation in water, the props would be smaller, due to the density of water. In times of peace, a little positive buoyancy, in war, negative. These props reverse thrust, so it would be a great layout for a sub if you mainly wanted to go up and down.

lol to all…
Just picking all, a was on the road all day.

Did you start building…?
This is just for Eric. Thanks for the offer, but I designed this over the weekend. It should be able to absorb some bumps with better results than the previous attempt. It weighs in at 219g. But that is with steel screws and nylon standoffs. The distance between motor shafts is 406mm / 16". This frame, and a little more accurate set up, should yield a lot better results.
Look real nice…
I want one… lol
Good to know you keep fighting… i was a bit worry
Here is an image of my quad all built up. The weight is 750g exactly! I also included a closeup of the landing gear and how it is used to stiffen the lexan. I have flown it, but it needs tuning. just waiting for some nicer weather.
Now back to work for me. lol
Looks good!
You like Lexan for this? Probably because you can cut it on your laser? Doesn’t it fracture easily?
How long is an “arm”, maybe PCB stock could be used?
Curious what Pilot/IMU you’re using?

This is my PCB shield…
MultiWii software Arduino… !
Real nice picture Jim…!
I like it.
I like strong materials. Yes it is cool to be able to cut it in-house.
Lexan, polycarbonate, difficult to laser, strong but flexible.
Plexiglass, acrylic, easy to laser, less flexible but very brittle.
The motor to motor spacing is 16" or 406mm.
Yes PCB board stock is commonly used. Lexan is easier for me to work with, so viola a Lexan chassis…
If you study the motor mount you will see how the interlocking parts add structural integrity. I’m cutting a new one today that has all of the holes and slots skinnyed up for a more tight fit. I.e. 0.125" hole actually measures 0.135" when laser cut. This is too large as the screw is actually 0.115" when measured. So the next revision will be even better.
I will post a video hopefully next Monday.
