I got some of my 'decals' and windows painted on. I balanced it with 30! grams of weight in the nose (takes it up to 150 grams without prop or rubber) and tested it for a glide. Beautiful. Nice and straight. But I don't have anyone to take pics. And I have the covid, so I can't use the neighbour either.

Thanks Tom. This is where we are at the moment. Fuselage tissue finished with 2 coats of dope. Nose won't be closed in until the plane is balanced. Weight at 124grams.

I am still working on this. I started covering and had to strip tissue off. This is the second attempt on the fuselage and nacelles. The bottom of the fuselage is double-covered with the second layer cross-grained to the first. I will do the same for the bottom of the nacelles. Because there is no landing gear, the tissue will have to take impact with the ground on its own, thus the strengthening. Not finished yet of course. I have some tissue repairs on the wings to finish as well. This was just to show that I haven't given up on it.

Yes. It worked quite well, but it covered only a very small gap. The more flexible the dried glue is, the floppier the joint would be.

Bamboo is a very hard wood and would be difficult and time consuming to make that many scarf joints. It was much simpler to sand the ends square and butt-glue the new piece in place, then add the supports later. Those little pieces of cardboard added a miniscule amount of weight. Stripping the bamboo wasn't too difficult. I used a sharpened Craft razor blade and stripped by eye and feel. Some skewers wouldn't strip evenly and were tossed, but others were good. There was a lot of scrap, but the skewers were cheap.

Outstanding.  I'd have been tempted to try a scarf cut to join the two pieces of bamboo.  But I don't know how you were able to strip the bamboo so consistently.  I've heard of some folks using 1/32" basswood but it's very hard to strip into stringers because the basswood wants to follow the grain and not cut consistent 1/32"X1/16" stringers. 

Your stringers look great!!! Smiley

It took some time and patience, but the old stringers were removed and replaced with bamboo split from some bamboo skewers. The split bamboo was about .75 to 1.0 mm, roughly square and just over 9" in length. It took about 3 pieces to get from nose to tail. I used small pieces of corrugated cardboard to support the joints. I added a piece of posterboard just behind the canopy for tissue attachment and two pieces on the fuselage just behind the TE to grip when launching so that I don't punch more holes in the tissue. Current weight without props is 114 grams. I think that it will take about 10 grams of additional weight in the nose to balance properly.

Back to the fuselage. I accidently crunched the nose a bit, and decided I had to add a little bit of support with bamboo stringers and a bit of bamboo (circled in green) to strengthen the posterboard supports. I used a piece of 1/64 ply to strengthen the main spar joint. I thought a bit about strengthening the front and rear LE joints and I remembered an engineer in our homebuilt aircraft club who designed his own seaplane. He demonstrated to us a quick way of strengthening joints by using strips of fiberglass cloth soaked in resin rather than ply gussets. So, I used a strip of coffee filter soaked in glue wrapped around the joints. I also added a bit of posterboard at the LE of the wing to attach the tissue to, and some posterboard over the small gaps between the fuselage and the rear part of the wing root ribs.
