I'm designing my own profile, and was wondering if you all thought that this airfoil shape would be ok.

In the great work done by Tattoo and Kraut in the SPAD world, they have found that this airfoil does not work well. A flat top style works OK, but a rounded, teardrop is the best.

thats what i thought...i was just trying a different way to build a rib due to limited construction tools in a dorm

Try the vortec airfoil!! It's really the best for 3d!!!!!!!

Here's a thread that Boogie started on that airfoil. Thanks Boogie!!!

i was just trying to avoid having to use a scroll saw to cut the parts, and as i thought, probly won't be able to. too bad i can't use out Stereolithography machine here to just "print out" my model and fly it! thanks for the input

You don't need a scroll saw. In fact, I get better cuts with a nice, sharp hobby knife. I've tried using my band saw and scroll saw for these things, but I always go back to my knife.

I built an entire P-38 in college with nothing more than the kit (had to cut all the pieces. They were just printed on the balsa), my hobby knife and glue. It turned out very nice.

no problem. I thought that if I had learned a lot from rcuniverse users I could also help them. That's why I have firstly seen this airfoil working and then shown it over here.

Use your hobby knife. It's the best. My Komacro's fuselage has a lot of lightening holes-everything with a hobby knife!!!!!!!!!!
