1.6 units control wheel deflection pops the spoilers on the NG and 4 units creates full spoiler pickup. Use as much spoiler/aileron as you need but as you lift the nosewheel at Vr allow the a/c to weathervane slowly by relaxing rudder then reducing aileron input to almost zero. If you get airborne cross controlled in the NG with a 40kt crosswind you will need way too much aileron input which aint good when the donkey fails and it aint good for accurate IAS readouts either.
