The Cats Meow!

Hi guys, a couple of days ago I went to my local rifle range and scored huge! The bow & arrow range was being dismantled and everything was 60% off. I scored on Beeman Hunter 500 carbon arrow shafts for 2 bucks each so I picked up a bunch, drew a small wing outline on my work bench and came up with this little wing. It looks a lot like the Diamonddust of old but much smaller and with the arrowshafts it is sturdy and light! I hope to maiden within the next few days. I also saw the cg calculator on this group, wheewww that's going to save me some head aches. Keep building 'em! Joser.

That's a great looking build. Super clean!!! I'm impressed. Did you happen to take any pics before it was covered? Also, what is the wing span.

Good luck on your maiden.

Greg

Hi Greg, thanks for the kind words. I did not take pictures of the build but I will be putting a few togetehr for the gang. I'll take lots of pics and do a build thread. It has three arrow shafts and about ten pieces of wood and goes together in a couple of hours. Keep 'em flying! Joser

Oh my gosh, there really is another draw a outline and build nut in the world. I frequently draw it in my head then lay it out on the balsa sheets starting with the fuse. For what its worth, have found I can cut 1/2" sheetrock sheets to my workbench size and save the bench finish. You can then draw on them, use them as a pin board, cuttenboard, and use both sides. Have 4 layers on the bench now which will last me many years. Try it, you will be happy you did. ENJOY

Roger, I tried your idea of sheetrock and it worked beautifully! Thanks, I will be posting a build thread soon.

BTW I maidened the wing and all I can say is WOW!!! how much fun can be had for so little. A 15 dollar motor, 20 bucks for an 18 amp speed control, 10 bucks each servo and away we went and oh...so fast! I will post the plans and everything else here for those that want to give it a try. Later, Joser

Your wings look absolutely fantastic. So smooth and clean . I hope you do a video as I would love to see it fly. Lately I have become more interested in front drive wings....yours is an awesome example.

Thanks Greg, I will have one of the guys at the field do some video work for me and I'll post it. Tractor wings, for some reason, are a bit easier to build & launch for me. I do have a stable of wings that I have built over the past couple of weeks and tested, most are very good machines and I will post the cats, that is one good flying wing! Keep up your endeavors with the whizzz. Also , have you been to Martin Hepperle's web page? He has a bunch of very good data for flying wing airfoils. I made 65 different wings for a particular wind tunnel study at a very prestigious university back in the eighties and we made a flying model that reached over 200 mph on the slope. Keep developing and testing your ideas, they'll pay off if you stick with them, Joser.

Building this wing should start like any other scratch, cut all the parts out first to make a kit. The hatch is a piece of phenolic. All parts are 1/8 balsa because I have more than 100 sheets of it!

Here I am putting the fuselage together. A small triangle and some quick Ca make this an easy job. The motor mount is made from 1/8 ply.

Next is to align the trailing edge. Here we are using a couple of jigs to level the TE to the fuse and make sure it's square. Then do the same thing for the spar.

After all is square and true, glue the wingtips and anti-torsion webs between the spars.
