Well, it's been along time since I've posted anything so hear it goes!!! A new 1/2A Shocer, 280 sq. in. wing area, pwr. is a Doug Gaulbreth .05 Picco. Weight is at 7.3 ozs. Initial test glides in the front yard are very promising. Pics. attached.

Maybe I'll get to see a test flight in the next few months. Looks good, Scott.

Scott,
Are the diagonal mylar strips you have on the wing and stab on top or underneath the covering.
Do they add much rigidity to the structure.

Ed, good to hear from you! The strips are actually Polyspan and they are under the covering. I apply them with dope than shrink them and apply 2 coats of 50/50 dope before applying the ultra coat lite material. I started adding this on all my nostalgia plans and it really helps with the rigidity of the wing. So I said to my self, self why not on everything so I did. Adds rigidity to everything which is a good thing. If you're not covering with plastic you could put it on before or after, I've seen it done both ways!!! Tissue is good also on really light planes such as the rubber jobs you fly. Attached is a pic. of a Ramrod wing with the added Polyspan strips.
