Default Inflatable RC Planes: The Future of Slow to Medium Speed RC Flight?

Last year I built an inflatable RC plane. The idea worked well as a proof of concept, but it will need some more work before it becomes a true RC aircraft. It also takes, hours, and hours, and hours... and hours to build. The result of all that hard work? A plane that can take most any crash without any repairs, can be stored in a crayon box, can use wing morphing, works really well at low Reynolds numbers, and can be fixed by covering any breaks with tape, then be re-inflated. It's only weakness of course is very rough or sharp things, but depending on the material thickness and choice, this problem can be significantly reduced.

"Crash without any repairs"? Hell, fill them with helium and they would be practically crashproof. Flyaways may be a problem though...

Didn't someone make a round one at some point? Kinda like a giant ducted fan? Similar to this but inflatable.

What is that bad-boy called?

Sadly the electronics will probably make the plane heavy enough that adding helium won't make it fly away. It would increase endurance though, especially on a fat delta wing!
The materials for the plane are really cheap. I spent $40 on a roll of material, and after 3 planes I have not been able to see a measurable change in the thickness of the roll. The manufacturing process would be pretty expensive though, especially if they are made by hand. It would cost $70 dollars in human labor in america if the system were mast produced by hand, or $7 in India(WARNING: Political Satire!). Just imagine keeping your 1/16 scale plane in your glove compartment, or your 1/2 scale plane in your duffel bag! Plus, It has a higher stall angle! Anyone want one? All you need is a mini-iron and a large sheet of mylar, and... wait for it... wait for it...wait for it...a massive amount of MATH!

BTW: before I balanced the model I crashed it strait into the hardwood ground at a good 10mph with homemade soldering on a circuit board 2 inches from the nose, and after probably a dozen such crashes I saw no deterioration in the plane, or in the delicate electronics!

Someone was converting inflatable pool toys to fly recently. Lol!

haha. Pool toys have wings that are cylindrical, the math i referred to is used so that you get an actual wing shape

Here you go on the inflatable pool toy RC airplane this was flown at Neat Fair in NY.


Found it there is a better video of this inflatable pool toy, but this is the one I just found. If I track down the better one I will post it.
