Could anyone suggest a book or two on designing planes?  Also, if there
are books on scratch building I would be interested in that as well.
What I am thinking of doing is building a canard sailplane (for fun,
since I haven't seen one before.)  I would probably start with a slope soarer
since I could use foam cut wings to build that.  Speaking of that, I need
a recomendation on a book about cutting wings (and a source of foam
in the kw area.)  

Finally, if anyone knows how to get lift curves and stall characteristics
for wings (especially for the set of wings in the plotfoil program),
I would be very interested in that.  How much force one gets for the
ailerons, spoilers and a front flap (a trailing flap force is easy to
get given the aileron information.) would also be useful.  Given equations,
or a pointer to equations I can probably work things out myself.

Thanks,

Bill
