Default poor lateral control on a slow tow?

With every flapped glider I've flown, negative flap improves aileron
response fairly dramatically. Positive flap does lower the stall
speed a little.

I've flown a 20 meter Nimbus 2C ballasted to 11 lbs/sq ft wing loading
behind a tug pilot accustomed to towing 2-33's. The speed was low
enough to need +1 flap but it didn't wallow. The tug pilot turned off
his radio when he got tired of me yelling for more speed than what he
"knew" was right.



Sorry if this is an obvious question (never flown a flapped glider), but
with an integrated flap system what is the relative movement of the
ailerons and flaps? Presumably the ailerons don't move at all for
negative settings?
