Thanks Troy - the servo extension is an easy to check possibility that
hadn't even occurred to me!  I don't think the surface is too heavy -
this is a .40 size Sig Somethin' Extra that I've been practicing the
sportsman sequence with all winter (on skis no less).  Don't laugh too
hard - the plane is capable of flying the sequence quite a bit better
than I am at this point ;-)  Besides, I've got one side doing it and the
other side not with the same servos in both sides.
