I love unusual gliders, so nice to see something different from the norm. I'm looking at designing something similar to a Swallow's (bird) planform, this has both swept forward and swept backward main wings and a V tail - any tips on design?
A million years ago I saw an article on the seagull slope soaring model made for the movie Johnathan Livingston Seagull. I think it was RCM Magazine. Maybe there is a way to search archives?
Love it. Way back when... Like during WWII... when materials were scarce, we built free flight birds from cardboard and paper stock. It works fine. I'm glad to see someone bringing this back to life. Probably won't win an F3J, but I'm sure your having fun.
I had more fun designing and building than flying. I read a magazine article in the early 70's about building with cardboard and decided to try it myself. Good thing I took drafting in high school. They are on the heavy side but with enough lift...
Welllllll... there's a lot more to it than you might think. The computer programs I used are RC Cad for the fuselage, wing placement and tail. Tracfoil for the wing ribs. The formulas for wing area, tail area, balance point etc... came from a book I can't remember the name of. I'm sorry, don't have time to draw up plans, the only plans I had were computer printouts of the fuselage side and top view, and the wing and tail was layed out directly on the cardboard.
OK, Ok, ok. I built it 5 years ago and was looking at both jets before I decided which one and it must be the YF-23, but I am far too lazy to go back and re-edit it. Thank you for you comments.
Can you please tell me what type of cardboard the wing was? Was it the corrigated sandwhich type cardboard that a television would come in for example? What thickness was the cardboard?
The cardboard was about 1/8 inch thick. Regular corrugated. The cardboard was used to put between layers of boxes for shipping. I see the same thing used at Sam's Club and Costco on their shelves. You might try asking if you can have a few sheets. Obviously you layout the wing to bend with the corrugation, tapered wings require more layout than straight wings. At the trailing edge leave 1/4" aft of the ribs to glue to each other for 1/4" balsa aileron stock. Need more info? let me know.
1/8" thick regular corrugated cardboard. Mine were used for placing between boxes on a shipping pallet, same as Sam,s Club, Costco or other warehouse store. Score the inside of the leading edge, with the corrugation, with a pen so it bends easier. Leave 1/4" aft of the ribs to glue together to match 1/4" aileron stock. Cardboard ribs with balsa reinforced LE. Contact cement, brush or spray. Need more info? Let me know.
hey that F22 raptor (think) looks great. it also looks very stable. i recon it may be the CG a bit far forward if the rolls barrell .. anyhow great plane 10/10
u cant beat cornflake boxes .. even beer cans & ice cream sticks .. ha ha weve been there too. people thought we were crazy. damn that glue cost ££-$!my latest creation is foam & card.
inspired

Your F-22 is actually an YF-23, one of my favorite planes.

Yes, someone pointed that out before. My mistake. I watched your Talon video, cool plane. I had one for a while.

My kids have made up their own chuck gliders. They would love to make something like yours if you could make up some sort of plans

Good point, if i kick you in the arse how much lift do you think it will need to make you fly?

That is not F-22, is YF-23. Anyway, it's beautiful.

I have never been satisfied building kits. Nobody makes what I want or it costs too much so I do it myself!

Thanks, I love unusual subjects. I also did a Schoenfeld Firecracker slope plane. I think I like designing more than flying!
