Riser wing is coming together

Some progress with the wing. Final sanding needs to be done still, and the spoilers should be tested once more before covering the wing.

I managed to break some structures while building, so I already have some experience in repairing the damage...

Wing joiner is a piano wire in brass tubes. Some spackle was needed after my attempts use two layers of 1mm balsa when I ran out of 2 mm sheet.

Some progress with the 2m Riser

The left wing is taking its shape. The spoiler mechanism seems to work ok. Some more sanding for the LE and the tip.

The wing will be in two pieces with dovels at the front and vinyl bolts on the TE. The wing joiner will be made from brass tubes and a piece of piano wire like in the Riser 100.

I have not started the fuselage yet. Instead of power pod I was thinking of earlier, I am considering to make two swappable nose pieces. One electric and one for pure glider mode.
