Those are showing up just fine, Paul.
I don't think you can attach but one pic per post like you are. If you have them hosted on a different server you can link to them with the IMG button up above.
Neat looking plane, BTW!!

Now here's someone who doesn't take chances... is that a carbon reinforcement I see shining though the covering?
How does it fly? Low speed handling... high speed handling?
How much wing area does it have?

Thanks, Chuck. Good eye, R-boy. Yes, that is carbon fiber, and its under the glassed center section (between the ailerons). Because I built the wing so thin (3/4" at root, 3/8" at tip), I sheeted, carboned, and glassed it. It is stout.
Specs: 46" span, 400 sq. in. I am guessing that it weighs in at around 3-1/4lbs, given the number of quickies I have held.
Low speed: It is a floater, with the light wing loading. Not much drag to slow it down either. It takes awhile to come down.
High speed: Flys like its on rails. Very quick and aerobatic. Lightning fast snaps at 120 mph or so. I have no fear with that wing. However, I did a couple of full pull turns and half loop reverse turns, and it liened out bad. How do I fix that? I wanted the pipe high because it was originally intended as a hand launch. But I fly off a paved runway, so the quickie gear and wheels were the way to go. Otherwise, I would have mounted the engine at 90 degrees.

Well I seen that thing fly today and all I can say is holly cow!!!even with the wore out sloppy jet it still was the fastest prop plane I have ever seen and could turn on a dime! Way cool Paul,the best thing was the landings, it just floats in.

That's a great looking Wing!
What airfoil is it?
Did you hotwire the foam cores yourself?
Would you be willing to hotwire another set for fee?

Thanks, Darin. It is a fun one to fly.
Esten, it is a built up wing, but foam would be a good way to go. Here is a link to the original Fuma.

I took Fuma designer Jeff's ribs and thinned them out considerably. I borrowed the wing shape from the Fuma, but it is otherwise all new. Given that Jeff was building Fumas to race with OS LA 15's, I decided to start from the gound up for Jett 50. Jeff relocated to Texas, and I not sure if he is still producing the kits. The plan has the ribs on it, and I may still have the plan somewhere in the garage. I could mail you a copy if I have it. Let me know.
