Hmm, not sure if this is a new forum or just never noticed it before?
Anyway's here's a question: I've built at least 3 Great Planes large Arf's and the thing I noticed about all of them is that none of em suggested putting a strip of glass down the center section of the wing. I've done it anyway's as a matter of habbit from building numerous balsa kits. Why is this never mentioned and is it not neccessary? Seems to me that it would be mentioned?

Thanks!
