Well, I had two problems with my plane at the last contest. First was a flight issue. You'd think by this time I'd quit doing this. Paul Walker told me a long time ago not to, but I'm kinda hard headed. I build this plane with identical flaps and put tabs on the wings to make up for the difference in wing length. the plane has about 5/8" of asymmetry. Anyway, it flies pretty well, but has some weird quirks in turns and seems to not be able to decide if there is too much tip weight or not enough. Remembering the previous conversation with Paul, I decided to cut the tabs off and build new flaps. The original flaps were a bit torsionally weak and for reasons I will never know, the silkspan was separating from the flap surface. Something was weird, but it doesn't matter since they are now in my trash can.
The other issue was an actual crack in the fuel tank. The tank has a piece of tubing through the middle and is secured by a nylon bolt (ala Ted Fancher). I've done a lot of tanks like this and never had a problem. But I forgot to reinforce the area around the tube on the top (I did it on the bottom). So of course the thing cracked around the tube on the top. Go figure.
Here are a couple of pictures. The flaps are built, but not shaped yet. Right as they sit there, they weigh just a bit under an ounce each. but after shaping, will be around 3/4oz each. That half what the original flaps weighed. And they are pretty stiff, too, without covering. They are also a touch bigger than the original flaps. The plane is a bit, ah, portly and the additional flapage should help.
