Not so much to report. Very bad weather and steady progress.

In the mean time I did some work on the wing. I glued all the ribs in place. That requires quite some fitting and alignment before everything is in right position. Then just some drops CA will do the trick.

And almost forgot to report; I changed the leading edge support from 1,5 ply to 2 x 10 mm spruce. Required only a little bit of reaming.

Lessons learned from Bananaman (see rcgroups) ; there is risk of bending at the tip of the wing. For that reason I have added extra supports to every rib. The balsa supports on the leading edge measure 24 mm. These supports will hold the weights on the wing when it is sheeted.

The main spar is getting into shape. I like this design. Its like a tree, strong at the base and getting slimmer to the top..

I have now finished the sheeting of the top side of the fuse. Next is to cut the supports such that I can turn it around for the bottom half. But before closing the bottom side I need to install the retract for the skate and servo's for the rudder and main gear. Most is well prepared already but I decided to move the rudder servo aft of the pilot. That will ask for some clever solution... :?

Some progress on the wing. All top stringers are in place. The balsa fill-in for the leading edge is also done. Ready to do some sheeting!

Switching between wing and fuse all the time..I have cut the fuse supports and now I can start the work on the bottom side.
First the bottom side of the wing shoulders. To support the ply sheet, some extra balsa is added.

I have a question; I noticed that the ply sheets suffer from some bubbling due to swelling. (not sure I use the correct wording.. :? ) This is caused by the high humidity in my hobby shed as I am not heating it all the time. When I heat the surface the ply flattens again. Now I might not need to worry so much as all the ply surfaces will get covered with epoxy resin, but the inside will not. So I suppose that humid conditions will continue to cause some problems. Therefore my question; do you have similar experience and any advice to avoid this problem?

I have started the sheeting of the first wing panel. I take it piece by piece. This to get some control and to not run out of clamps.
