Here's your checklist for a CV takeoff:
1. Check rear view to see if CV's turning. Let it straighten out if it is.
2. Apply 1 notch of flaps.
3. Throttle 100% + WEP as soon as your wheels roll.
4. As soon as your off the carrier deck, pull back a little on your stick and raise gear asap. Once you have positive air/climb, retract flaps and release WEP.
Note: Zekes and the Seafire are good AC to get the feel of a CV take-off. Next try light Corsairs with 50% gas. Once you're comfortable with that, try adding bombs, rockets, more fuel, etc. A full loaded Corsair (2 1,000k bombs + rockets + drop tanks + 50% - 100% fuel) takes practice.
