Hi Troy!

First, thank you for this most excellent thread.

Second, I just received my ARC version of the focus sport (largely inspired by this thread!). I figured that the ARC version would be an uncovered incarnation of the ARF, but I've discovered an important difference. It seems that the ARF version comes complete with the fiberglass tube receiver for the aluminum wing tube already installed in the fuse. The ARC version does not.

In examining the pictures of your ship, I see that the tube is installed with plywood ring doublers on either inside of the fuse. I'll have to create these myself, since the kit doesn't seem to include them.

So then, do you have any advice how I might get this install step done with precision? I know this tube must be level to some reference in roll axis (canopy rails?), and square to the centerline of the fuse in yaw axis. I'm not entirely sure how to get this right.

Any help is much appreciated!

Edit: it is worth mentioning that the fiberglass tube is not a perfect slip fit into the holes in the balsa fuse sides. There's about 1/16th inch play, just to make it interesting lol.
