Bipe Flyer

Thanks for all the suggestions so far. It's no easy task to design light, strong and still have it be what every person considers to be good trainer. I like the feedback though as it means that it is a worthwhile project.

Remby,
I'm not a big fan of crash proofing, but a dowel leading edge could be another option. Again, this is where I would prefer a foam core wing because it has a very good strength to weight ratio and is easily repairable. I will probably add doublers under the wing or possibly between the firewall and first former, although I rarely use doublers when building for myself.

George,
I really like stick formers. I think that they give the most strength for the least amount of weight. I don't like using ply unless I have to. You're right, I haven't drawn any shear webs yet. They should go between the spars, but I will probably draw them on the back of the spars as this makes building easier.
