Does anybody know how to make a crooswind take off in FS2002?

Correct technique is to apply full aileron in the direction of the wind (i.e. if coming from left give full left turn with aileron) until you get near stall speed e.g. about 40 knots in 172. Use the rudder/nosewheel to keep nose straight. When rotating let nose swing to guage strength of crosswind, apply rudder to centre the turn and bank ball and dip one wing into wind in order to maintain runway heading. Practice!!!
