I'm up to the wing stage and have fitted the outer spars, The main spar feels solid as a rock as one would expect. But the aft spar feels kinda flimsy to me !! The main spar has no movement at all but when I flex the rear spar at the tip it seems to flex quite a bit and doesn't feel at all like it'll take much of the lifting forces. Does this sound quite normal?? It seems to me that the rear spar will mainly take the fore to aft loads encountered from wing drag.
