RE: TT New Version Decathlon Build
Yup, the wing appears to be fully symetrical. I would also say the struts are required... though maybe not structural (load bearing).
There is a large fiberglass tube, about 16" long that slides into the fuse, then the wings slide onto the tube. The only thing holding the wings onto the tube, is a screw on each wing. There's a predrilled hole in the wing, and you just have to finish drill into the tube. Run the screw, one per wing, that's it holding them onto the tube. So, the wings get a lot of strength from the tube, but the only thing holding them ONTO the tube, is one screw. The struts probably aren't needed to take the load, but they have a second job, which is to form a rigid triangle, which helps hold the wings from sliding off the tube.
I don't have any experience with two piece wings. Maybe this single screw retention is normal. But I won't fly without the struts, cause I think they help hold the wing on.
I mounted the fins last night. Both the vertical and horizontal go on at the same time, since the vertical plugs THROUGH the horizontal. They appear to have come out totally square with eachother and the fuse, without much effort.
And that's about all the gluing required for the kit! The wings are two piece, and the firewall is already fuel-proofed! It's just bolt on from here.
Well, there are some CA hinges, but I'll be replacing them. They seem a little smallish to me.
The rest of the hardware is fine though. I will be using the clevises and control horns. They seem just as good as Dubro parts. The wheels could pass for Dubro too, they just don't have the name on the sidewall.
The pushrods also have a nice chrome plating on them. I am thinking about replacing the wood elevator pushrod with a fiberglass one, just for stiffness.
