Flat, packable... folding wing or delta?
I'm on a quest to create a flat, packable flyer with the express purpose of carrying an 808 key fob camera for aerial photography with me when I travel. So... doesn't need to be big or carry a big payload (17 gram 808 camera). I would like to be able to fly in a range of wind speeds because you never know what you'll find when you get there. It does need to be able to fly slow and stable for nice, smooth video from the camera.
There is a nice flying wing design in the Scythe thread that has been made foldable (with stub spar and magnets) and I'm also looking at deltas like the Superfly or HyperFlea (maybe with removeable fins?).
129g 24" (total wing span) Travelling Scythe
My plane will need to be built light to fly slow but there is also that "range of wind speeds" issue to consider.
What does "packable" mean? I think I'd like to get the size down to something that would pack flat in a suitcase that you can "carry on" a commerical flight but slightly larger would be OK too if necessary. I mostly travel by car (but not always with a lot of luggage space on family trips).
The maximum size carry-on bag for most airlines is 45 linear inches (the total of the height, width, and depth of the bag).
22" x 14" x 9" United, Delta, NWA
24" x 16" x 10" Southwest
22" x 16" x 8" British Airways
Wingspan: 22 inches
Length: 18.75 inches
TSA / FAA restrictions on LiPo (Lithium) batteries
Here is a TSA site that discusses the issue:
Traveling safely with batteries...
"8 grams of equivalent lithium content are equal to about 100 watt-hours."
"You can arrive at the number of watt-hours your battery provides if you know how many milliamp hours and volts your battery provides:
mAh/1000 x V = wh"
Since I want to fly slow I'll build light and probably use something flat like:
Rhino 460mAh 2S 7.4v 20C Lipoly Pack
Calculation: 460/1000 * 7.4v = 3.4 watt-hours
So... looks like I'd be OK (by a fair sized margin)!
Other restrictions seem to be no batteries in checked luggage and not more than 2 "spare" batteries (not installed in the device). Batteries need to be with you in the plane (not gate checked).
