I have seen one fellow using slight cross control on takeoffs with a stiff crosswind. With a crosswind from the right, a slight amount of right aileron to keep the wind from getting under the right wing and a slight amount of left rudder to keep her from weathervaning.

Actually saw it done successfully with a 1/3 scale J-3 Cub. I've never tried it myself and pretty much take off using only rudder corrections. The one exception is on a flying boat type hull where you need to keep the wings level (and the sponsons out of the water) while on the takeoff run. Does sometimes result in very slight cross control. But this is not the result of crosswind but rather a slight imbalance in the lateral CG
