trying to research phenomena

[dbhenry1234]

I am starting to look into what happens when a propellor is larger in diameter than the wingspan of the aircraft, by about 5-10%.

does anyone have any experience into this, or know of any places to look?

One might wonder why... :)
But in general this idea has been done.. the machines are called helicopters.
Research has found that long skinny blades work best for this application.
.
For models, which is what I presume you're going to try, electric motors and gearboxes on a testbed, with a "wing" could be tried with a normal motor/gear/prop combination.
I'd suggest a vertical orientation for the machine ala the Lockheed Pogo.
Expect some torque reaction... Keep the hands clear when running the motor up! :D
"wing spans" must necessarily be short, as long props are rare, and expensive!
Keep us informed... with photos!

Better use a folder, since I doubt you can get the LG long enough. It would be fun to have a plane that lands on its tail, but it might take some practice before you can manage that.

the plane is actually intended as landing on its bottom side, sans landing gear! (prop is an expendable commodity with this design!)

Horizontal take-offs should be interesting - and the undercarriage should be a sight!

Can't wait to see what it looks like. (4 inches span, slow prop, camera carrying by any chance .......?)
