Pretty sure the forward sweep is a C/G thing, useful cockpit load and
all... *also takes the place of washout, but the C/G thing is more of
a challenge to design around. Agreed on the topedos though. If someone
made a decent composite wing for the L-13, it really should work well.
Plain flaps instead of complicated/ineffective fowlers, and simple
Horner tips...

Once you've made -- and certified -- a new composite wing to bolt on
to the ungodly uncomfortable cockpit (metal bar right through the
small of the back??) and constantly damaged tailwheel of the L-13, why
not go the whole 9 yards and put a new composite fuselage to go with
it.... and reinvent the ASK21.

Really guys, I've heard some nutty ideas on r.a.s, but this must take
the cake. Don't you think the eddy current test or even rebuilding the
whole darn spar might be a bit cheaper and quicker to certify than
designing and building a whole new wing on which to hang 30 year old
fuselages?
