RE: Bi-Plane all wing kit???
Actually, the U.S.Navy had a tailless biplane during the First World War- I think it was the Burgess-Dunne. With sweptback wings it looked very cool. Not likely ever a candidate for a kit, though.

RE: Bi-Plane all wing kit???
Popular Science did an article on one in 1976. There was a guy up in Milwaukee who was building them as an ultralight for sale.
I'm looking for a kit/model to build one or planes to build it from scratch.

@ Dave Segal:
I don't know if John Gill is a member of RCU or not, but he's sorta local to me, and is the sales manager for Polk's Hobby. He has built a beautifully detailed Burgess-Dunne model, which I grilled him about at last year's Hope Electric Eagles fly-in. If you're interested in that plane, he'd probably be a good resource.
@ Todd J:
I don't know of a "hobby grade" electric biplane flying wing, but Toys-r-Us used to sell an Airhogs "Sky Surfer" biplane; it was 2-channel control with differential thrust steering. It was reported to fly pretty well, and IIRC, there was some discussion on RCGroups about converting it to more conventional radio setup.

Yep. He said that's why the plane interested him in the first place, since his first love is yacht models. I *think* he said he did one test hop on Lake Hopatcong and then shelved the model for display, Kinda like Howard Hughes with the Hercules.

Found a 'tailless biplane' while doing a search for something else.
It may not be what you are looking for, but would make a fantastic looking model.

Hope the site owner doesn't mind me showing it.

Not exactly what I had in mind.
Here's a link for what I'm looking for, would just have to figure out how to motorize it.

Mmmmm!
A tricky one there, you could do it scale with a 'motor' mounted off the frame, but what would you do for controls?
A large dummy pilot could carry the rc gear and batteries, but I don't think you could use 'hang glider' control method of pilot movement.
It appears to have tip rudders, (or drag devices), but I think an elevator control is still needed. If the pilot had been in a more prone position, (instead of legs nearly straight down), you might have used his legs as an elevator.
Fitting elevons would work, but loose the scale effect.
Good luck with trying to fathom it out.

RE: Bi-Plane all wing kit???
My thought was to dump the pilot guy all together and not worry about keeping it to scale, but just maintianing the basic concept. However it sounds like this idea/design would be very difficult to implement, and although I have a great deal of skill in building airplanes, I probably don't have enough skill in the design/aerodynamics needed.
thanks anyways, it was an idea....
