Lets see YOUR crazy design
It can be a plan, drawing, or completed aircraft. Or maybe just a description of it. Mineis a flying cat. (the line on its head and body represent the wings that give itdepth and create lift) What can you think up?

Here is one of mine, a little unusual just for fun. use's only inverse ruddavators without ailerons, diesel powered and best launched with about ten foot of bungee cord. Why? dunno suppose just to see if I could. Yes it works.

RE: Lets see YOUR crazy design
This one isn't too wild, but since there is already a canard, I'll show it. We call it the CROCANARD, which is a contraction for Crocodile Canard.
As you can see, it is a canard, biplane with dihedral and anhedral, giving it an "X-wing" look. It turned out to be a good flying plane, but it took a lot of work.
It was built by my flying buddy, Carl "Flaps" Laffert with design help from me. I was the pilot. It always flew great, but the take off and landing were hair-raising. You always set the canard at a few degrees positive relative to the wing. This is so the canard stalls first. If the wing stalls first, the plane pitches up and you are done for.
The Croc has no rudders, only nose wheel steering. I've flown planes like this before, but I didn't realize that the nose would lift so soon. It's a good thing we fly from an old Navy runway that is about 300 feet wide. Once the power comes in, the plane is on its own until lift off. Scared the you-know-what out of me on the first flight. We added more weight to the nose. Still didn't help. Flaps moved the gear back into the wing. This put a large amount of force on the nose gear. Still didn't help.
We were at a loss until Flaps came up with a forward rudder. He attached a piece of lite ply to the nose gear strut. This actually allowed me to steer the Croc on take off. After this mod, it was like any other plane. The extra weight on the nose gear meant it didn't bounce on landing.

RE: Lets see YOUR crazy design
I have built about a half dozen of these over the years, from a TD 010 to a Merco 61 version. [ The club made me put a RC throttle on the that ! ]
Designed by Charles (now Doctor) McCutcheon, who studied nuclear physics at Cambridge University but was obsessed by minimalist flight. No one has cracked the problem of directional control yet.

very cool and I remember well a Merco I had in the past. Flew a .40 Merco just for fun last year that someone gave me.

RE: Lets see YOUR crazy design
Here is one for ya. This is a set of Piper Cub tail feathers that a couple of us hacked out of foam one day. We gave it some small elevons at the trailing edge, stuck a .15 on the front, and flew it!! The black hinge lines are just drawn on with felt pen for "scale effect", the actual hinge lines are further aft. Somewhere, we have a video of it flying, but I don't know where. It is actually surprisingly stable and gentle to fly.
