The lainer instructions are online, Midwest has a sample online.

From the lanier instructions ALL of the surfaces are foam. And yes that means the stab is airfoiled.

I happen to like foam because it comes out very true, but it is heaver and that matters a bit more in something of the cap's size.

I have an aeroworks too and love it. Right now I am building a Carden . . . LOTS of FOAM!

P.S. Sometimes it boils down to . . . you pay your money and you take your chances!

P.P.S. It is a shame that Power Kits (and ARFS) dont' tell you what airfoil that they use. IT would be another great way to compare the performance of two similar aircraft. If anyone is going to tell me Airfoils do not matter on a plane of our size bull. I have flown competition sailplanes too long and read too many wind tunnel test (at our reynold's numbers) to believe that!
