This was an accidental discovery. My own theory is that the prop wash points slightly away from the body of the copter. The cleaner the prop wash the smoother she flies.

I may try that on the next one. But i need to make a supply run

What's the flight time on that AUW?

3 blades should produce more lift, more turbulence, and may or may not be more efficient.

I had to pull out a metric ruler to get an idea of how small that thing really is. Love the fence and slide shots. The swan didn't care and the dog, barely. Looks like mission accomplished. Great build.

Nice one guy. Why you prefer aluminium than G10 or wood?

Flight time is about 10mn but I do only 5mn FPV for safety.

With this mini quad its fun to play with slide and other kindergartens.
Also wildlife and birds in particular are less afraid.

Hi all
the v.2 version of the Fold-A-Copter is almost ready!
Here you can see the new center plates, lighter and slightly larger but still very compact: what you see tipps the scale at 184grams... not bad IMO
I'll keep you updated...
Cheers

After completing my beautiful aluminum folding H quad, it did turn out to heavy :/ (pic one)
So I decided to make another one but out of carbon fiber rod that I had laying around (pic two)

The main objectives were to carry a GoPro and be able to run off of a 3s 5000 as I have four of them. The aluminum quad did get off of the ground but the frame had some torque issues and it look about 90% throttle to hover, not good. The new carbon fiber frame cut 1pound off of the design which is huge and now hovers at about 30-50% throttle, much better. The carbon frame does fold up I just don't have a pic of that yet.

Sorry for the crappy pictures, I'll try and get better ones soon

Hi Crazy1,
why did you use tubular tubing instead of "the usual (10x10mm)" square carbon tubing - my guess is that they would be stiffer and just as light.
