Title: Horizontal stabiliser question.
Post by: Shay King on January 16, 2026, 10:27:55 AM

On page 1 of the plans the innermost rib on the stabiliser has the note ‘Flat side’.
Does that mean that rib is on its side, whereas the other two are sharp sides down?
Also, the tubing between the gussets for the 3/16” bolts, what are builders using there. Is it 3/16” inner diameter bushing material or aluminium tubing with a loose fit?

Inner rib, opening goes toward outer tip, other ribs, opening goes toward inside end. I used aluminum tubing with 3/16" ID for my brace wire gusset supports. I used JB-Weld to epoxy them in place. So did my pal who is building his own XL in my shop.

Thanks Keith,
That all makes sense now.

Just for info. Homemade bender for the 5/8” tubing. Made from scrap plywood and steel.

 Guys, I’ve started on the elevators and have a question. I don’t see a dimension to locate the front central gusset/rib joint on the elevator. Does it line up with the rear central gusset in the stabiliser? Please see picture below.

Most of them I've seen turned out like this. I made my rib junction at 20" from tip.
