cardboard wing on baby ringmaster

That is cool. I would like to know the outcome. What is it covered with, and is the airfoil on the top only, or is it diamond shaped (top and bottom)?

Very cool. Over the years I've seen a few plan for scale models built from cardboard.

thanks. the air foil is top only to cut down on weight and i used ultracoat covering

ALMOST FINISHED....made the horizontle stab and elevator out of cardboard as well.I was surprised how sturdy this lil fella was and light too

Flying this tomorrow, 1'st control line flight in 40 or so years. Wish me luck

So what is the finished weight of the plane with and without the engine?

Hey- hey, best of luck.....break a leg
and have a blast. If nothing else,
you're getting your feet wet again.
She looks like a fit craft. Keep us posted.
Enjoy!

akjgardner That's really nice looking hope it flys well for you , yes flight report , I have seen a few people making airplane from cardboard but never considered tring it myself . Eric

Hey did it fly?

actually no,not yet, ended up geting busy and now it's been to nasty out

It just might fly better'n a flat winged version!

Hey Gardener, I didn't realize you hadn't flown lately, Good luck. I think the planes with diamond shaped wings tend to hunt, in other words, to randomly turn up and down, and resist your attempts to fly level. But your flat bottom(right?) may change everything and fly great I know you can take a flat wing and build up a ridge behind the LE and it provides decent lift. Maybe yours will act that way. If you finish your flight wondering how you could possibly be so bad Lol, it might have been hunting. That would remind me of the time years ago, I didn't know to be serious about tail weight My wife said, Wow! That looked like a fun flight. It was all I could do to stand up.

Thanks for the tip on the wing shape Rusty. I am a newby at CL but am looking foward to flying in the spring.I am building a couple half A's.I did get in a few flights last year and other then getting a little dizzy, didn't do to bad.

I never found a diamond shaped wing to hunt due to design but rather they tend to fly poorly. Any of the planes that I had that utilized them flew like stink in level flight but when the plane was put into a maneuver, the speed fell of so rapidly the plane would almost slide and fall out of the maneuver. The Sterling Viper which was Sterling's full body 1/2A used a diamond airfoil. I built one of these in the late 80's and it certainly looked cool. It flew fair but not with any kind of performance. A jumping Bean would run circles around it. When I graduated into larger and faster planes this was even more apparent. The Demon is a combat plane that used the diamond airfoil also . Once again, it seemed the faster the planes went, it was noted how quickly speed bled off. My suggestion would be to fly it fast if your looking for more than level flight.

If I were to guess (and I am..) I'd think that there would be a lot of turbulence created where the airfoil makes a sharp corner. Maybe it will prove to be effective applying it to only the top surface? I'd beware flying inverted though. You might need a lot of down-elevator throw.

Flew It today with my son, I have not flown in a few years.(40) To my surprise it flew pretty good and I did not get too dizzy. the v shaped wing flew fine . It tried to porpoise a little but not too bad .It got me and my boy excited about flying again. will try to post a small video later.

That's a post that makes me smile! Good going guys!

Way to go !! good to hear your team is getting out and getting some air time and that the plane did good too .
