Well, I am finally getting back to the Vireo. Stuff kept getting in the way and today I finally got back to the model bench. Even though my drawing shows a conventional wing, I am going to use a foam wing with a KFm3 airfoil. A complete description is in the attachment. I’ve built two carrier planes with a KFm2 and it works very well.

Construction is simple, the parts are cut from pink 3/8 foam sheathing. There are a number of different foams, I use this one because I have it left over from a project. I use carbon fiber arrow shafts for spars. I pick them up at my local archery range. There are always some broken ones in the trash.

Here are some pictures of the gear. I have used this method for foam before and it works quite well.

I almost feel bad about disturbing the quite of the carrier board, but I have made some progress on the Vireo. The fuselage is mostly blocked out, and the wing 90% finished. My goal of a total weight of 16-20oz is looking good, even though I forgot some lightening holes in the doublers. The weight with only a couple of parts missing it is 11.5oz.
