I always had problems with the transportation of my quadcopter and this is how i soled it.
This is my build step by step...
I had som plans for a foldable quadcopter based of David Windeståls tricopter and this was the outcome.
I made the quadcopter in 3 mm lauan plywood, its cheap and if something goes wrong you can always do a new one.
Consider it marked.. i taped it so it would be easier to saw.
I used a standard jigsaw to make the parts. The point by doing this is as i did was that i wanted to use as much materials that you can buy in a ordinary hardware store and use ordinary tools.
Testing the frame functions, I changed the positions of the arms after i first mounted it. The angle of the front booms where to tight when i folded it together. The booms are about 10" or 25cm (see the drawings in the end of the presentation)
I used a Hobbywing Quattro ESC for a tight fit and a slim look. Bare in mind that if you use a flight controller with digital compass its better with standard ESCs because it can create some nasty interference on the flight controller if its to close.
This was before i changed the front booms, it is a much better fit further down in this presentation.
I used a bit of vulcanising tape to tape the cables together so they shouldn't get caught in between the booms and the frame when you fold it.
Cables from the ESC and power cable to the BEC.
Some ugly green ties and we are one step closer to the end.
Some big as 1000kv motors, a little bit oversized but you take what you've got.
A special velcro for kitchen panels, it has excellent capabilities of reducing vibration so its very good to use on your flight controller.
A stripped receiver.
An ordinary straw makes a excellent antenna holder.
Just drill a hole and "woala" you have a nice bendable antenna holder.
So when you want to fold it and put it in the bag the antenna stays in one piece.
Antenna and lipoalarm.
Almost ready to test out on the backyard. I use a "Crius AIOP V2" flightcontroller, its the same as Hobbykings "Multiwii AIOP V2.0" and it works excellent.
I use a Hitec Optic Sport 6ch for this quad, i usually fly in Acro so it will not require so much channels on this quad.
Ready to test. Check out the video on youtube of its stability.
Here is a clip that shows the folding
Lets fold it... the back booms folds pretty tight.
and next the front booms and the antenna.
It fits in a small bag like a backpack so its really easy to bring
I use rubber from an old cd-rom to make the dampers for the camera, it has great capabilities to absorb vibrations.
I fitted the camera mount with the same velcro as i used on the plate before.
Ready for new adventures.
I hope you liked this little preview of my new foldable quad.
Have a glorious day.

Hope you like it as much as i do.
