Today I continued on the stabs. I cut 1" balsa on the table saw for the leading and trailing edges of the control surfaces. I used polyurethane glue to attach them. Poly glue takes some getting used too. It expands which is good with foam but if it oozes out it can be difficult to sand if it dries for more than a couple hours. So I always time it so I can sand any excess within an hour of drying.
I cut out an area for hard wood on the rudder to mount the control horns too. This was epoxied it. Especially on the rudder. I tend to do to many rudder touches in hovers.
The wings are prepped and ready to sheet. The 4-40 blind nuts have been installed. I glued and extra 1/4" ply on the root rib and then used the dermal router to cut the foam so it could be recessed. The phenolic for the wing tube is glued into place and I used ploy glue on this also so it could expand and fill any gaps. The end of the phenolic is plugged with 1/4" balsa and then 1/8" ply to support it centered in place.
I use 4 different grit papers on straight edges for the block sanding and sometimes a small planner to knock down the big stuff.
Hard wood for control horns.
I had to trim each elevator about 1 1/2" on the inside to get more rudder throw.
