advanced canard plans

Bob Banka's plans service has a 3-view. I have a book of X-planes that does -- if I remember I'll bring it down and give you the info.

I suspect that you could easily make it longitudinally stable by correct placement of the CG, but it may be hard to get it directionally stable without either a big rudder or a gyro -- and with a gyro you'll still have drift, it'll just get it down to a speed you can deal with.

I'd build lots of little foamy gliders before I committed to a nice model, I think.

Tim,

Thanks for the Banka link. I had previously heard about Bob, but had never used his service, and had forgotten about him.

From what I've read about the actual X-29, I think a lot of the stability problems had to do with a hypercritical airfoil that also was built to flex assymetrically. It also appears to have a small rudder, but since it won't be scale anyway, that shouldn't be difficult to fix.

I had planned on building a symmetrical wing based on a pattern profile (not scale), and probably lengthening the wings a bit. Although I want to build it as a pusher, it may not prove to be practical. After running some rough numbers through a CG calculator, it appears that the CG will need to be a good bit forward of the leading edge at the root.

Much as I hate messing with them, you are probably right about the foamies.

Bob
