RE: Dirty Birdy Flexing Fuse on ARF
What do you mean when you say "flexing fuse"? Do you mean that the tail wiggles from side-to-side as the model flies? Or do you mean that you can squeeze it and feel it move in and out as you squeeze and release? The first should never happen, the second happens with almost every molded model out there. Make it too rigid and it's too heavy.

That's why many of us that craft our own fuses resort to composite lay-up. Not only is it lighter than glass-epoxy alone, it is far stiffer.
Glass alone would produce the fuse you describe ("oil canning")

RE: Dirty Birdy Flexing Fuse on ARF
I don't understand the issue of "oil canning" of the rear fuse on the DB ARF. Mine does squeeze in at a point between the trailing edge of the wing and the tail feathers but it does not allow the tail to twist on the ground or in flight. Enlighten me, what is the problem??

If the flexing when you handle it bothers you ...... why not add a couple of balsa formers in strategic locations to stop it ?
