Default Stevephoon 3D - Take 2

My Stevephoon 3D is getting a new lease on life. I've replaced the original Hobbyzone Typhoon foam wings with new built up balsa ones I designed in WingMaker.

The new wing is made up of mostly old scrap pieces of balsa left over from other kits. The ribs were cut from a new sheet of 1/16 balsa, but the rest was scavenged pieces. 3/32 for the leading edge, stringers and wing tips, 1/8 for the ailerons, trailing edge and spars. I've added 2 in of wingspan and reduced the weight by about an ounce. It's about the same thick symmetric airfoil. I used a NACA-0021 that is built into WingHelper. I like the way the old wing slowed down and I wanted to keep the same slow flying characteristics.

Wing Parts Cut Out


Balsa Completed




Ready for Maiden!






AUW is 20 oz, and about 200 watts power. Not 200 watts per pound, but fun!

Taking baby steps to get to the point where I can create my own planes, and to get laser/or CNC cut parts.... That's really my goal.

I have found WingHelper really easy to use and it has a large database of airfoils to try. https://www.winghelper.com/default/ It's just for designing wings and is limited in many aspects, but relatively cheap and easy to use. For me, just the ability to print out Rib Templates is worth it.

Hopefully the weather will cooperate soon and then I'll throw her into the air!

Interesting

Should be a great flyer.

I will be building a light thick winged plane very soon, but the opposite way you did.
I bought a perfect set of wings for the E-flite Eratix, for only $10, so I need to build the rest.

Steve, it looks like Winghelper will export files in *.dxf format. If so, you can send those files to a laser cutting service and get your parts laser cut.
