I was going to add the plans, but it seems I can't attach a zip file to a message. Oh well, if you want them I'll be happy to send them over to you. There's some pictures of the finished aircraft along with the plans, I'll post them here so you know what I'm going for.

I've noticed that the plans aren't perfect scale - particularly in regards to the thickness of the wing next to the fuselage and the tank. I think I'll go for building them as shown in the plans, mostly due to the fact that I'm not too comfortable making structural modifications that could compromise the integrity of the final aircraft. And now that I look closely on the pictures, I see that the wingtips are indeed a flat piece with some reinforcement on top. Good, must get to building those.
