Not sure of your size dimensions, but the spitfire might be good for you with the removable wing.
If you want something pretty compact look over at Experimental Airlines on youtube, he has a flying wing called the Synapse. he shows how to build it so that it folds down in half, so it becomes pretty small for easy transport. I am contemplating trying that with my Versa Wing once I've crashed it a few times and it needs repairing
Thanks for the suggestions. I checked out the synapse; pretty cool, but a bit big for my tastes. I love that guy's building techniques though; his planes always look so clean and shiny.
I own something decent for transport, the Hobbyking Kinetic 800, a small, 800mm-wingspan glider which has 2 separate wings that easily come on and off the fuse. The stabilizer in principle should come off too, but I'm not too sure how to release the mechanism that holds it on without damaging it.
This plane relies on carefully molded plastic parts to achieve its portability, and I'm curious to see how it could be done with a scratchbuild.
You're right, the spitfire is almost there; with a 40" wingspan, though, that's a lot of wing sticking out of a backpack. Maybe what would be ideal would be a slightly scaled down version, and have the wing come apart in two pieces. Maybe the flite test crew can design a good joining method.
The most successful mod I've done to a plane to make it portable was one I did to a 1.5 meter glider: the wing came apart into two pieces, but the "limiting factor" was that the stab and rudder were permanently affixed to the fuse. I got some nylon bolts and nuts from the hardware store and installed them so that the rudder and stab get screwed on to the fuse to set the plane up.
