Let's get back to the build. This week I received most of the stuff I will need to finish the plane. I am still waiting for a piece of carbon sheet for the motor mount and a piece of carbon nomex for the servo tray. I have been pretty busy at work but I finally had a chance to do a little work last night and today.
I decided to tackle the aileron servo mountings. This is one spot that I will admit to being a bit disappointed with the plane. The aileron servo opening is rather large at just under 2.5 by 1.25 inches. I choose to use JR 9411SA servos which are quite a bit smaller than the opening. The lips on the servo bay are not very stiff nor long enough to mount this servo. Adding ply servo rails above the fiberglass lips and glued to the sides of the bay would have worked but the servo would have ended up too far out of the wing for my taste. I decide to make a small tray from .125 fiberglass covered end grain balsa. I really like this stuff for its low weight and strength. Luckily I had a few pieces left over from the center of a few formers that I made to build a plane back in 1991

I made a paper template as shown and then cut the fiberglass balsa composite to match. I added a light balsa rail to the edges that will glue to the turned in sides of the servo bay. The completed tray weighed 4.6 gms before gluing in place. I think Oxai could have put in a piece of nomex sheet in this spot that could be cut out for your servo choice. The only thing else needed would be something to screw into. This would be minimum work on there part as they make the composite wing. It took me several hours to get it done.
