RE: Composite wings, any advantage ?
I had the chance to (very gently!) handle and inspect one of the wings of Ken Velez' Bravo and these have got to be the cutting egde in pattern wing design and construction. Very light, strong and true.
I have no doubts about their strength having seen a fair number of Dave's snap rolls, which are of the very aggressive nature with a clear elevator break and not the somewhat questionable 'flick rolls' that are common these days. I would guess that some of Dave's Bravo wings have endured perhaps 8 to 10 thousand such snaps.
