Spoilers function the same as ailerons at low angles of attack and better
than ailerons at high angle of attack. The primary advantage of spoilers
instead of ailerons is that it enables full span flaps. Spoilers also
reduce or eliminate adverse yaw.

There are two old Senecas at my airport with the Robertson STOL mod -
full span flaps w/spoilers in place of conventional ailerons. I've seen
one of them take off with a brutally short roll, and it went up as if
on an escalator. My question is, how would one of these land in a stiff
x-wind? Is the pilot limited to crabbing approaches with a kick-out in
the flare just above the runway? Or is there no appreciable difference
with ailerons?

I'm hoping Mike R. will weigh in with his Shmoo experience. IIRC the
MU-2 has the same configuration.
