Hi all,
I received a few requests for a new tutorial, I made one a few years back but has been buried somewhere in the RCU data.
I will start with a simple subject: a flap for my current build, a 1/5 scale Me109 from fliteskin aeroscale.

The Me109 has 3 flaps per wing: 2 inner flaps (upper and lower that work independently) and the outer flap which I will build first.

Each outer flap has 4 balsa ribs, a balsa leading edge and 2 skins: upper and lower.
1st I cut both skins and sand the inner surfaces with 120 grit (edges and rib contact only)
I also sand the outer side of the skin with 220 since I will prime as soon as the glue dries.


Since the skins are semi transparent, I can mark and scribe right over the plans.
I can tack the ribs to the bottom skin with CA, and for some applications, it works.
For the edges I will use the original polyurethane Gorilla glue, which expands a little.
