O.K. Guys, still working on this. To get the full size picture, let me clarify for those who don't know. I just learned.
First double click on the picture...second, maximize your window...third, circle your cursor near the lower right hand corner of your picture and you will activate a symbol with arrows...fourth, click on the middle of this symbol...this blows the picture up to the RCU maximum. Nice smooth edges, good resolution.

CeeGee, I have a picture program called ACDsee which I used to get my avatar sized. I like your picture. Isn't that an avatar...or is that supplied by RCU?

This should be my last two pictures showing the 4-40 linkages. The canopy is coated on the inside with Testor's transparent blue so the pilot can look out. He was on break when I took the pictures.
Try to overlook the wrinkles in the covering, it has been hanging in my basement since last October.
