Do you have flight quadrant attached to your computer. You know the one for multiengine bombers. If yes, then unmap it from control settings (axis etc).
Then for the beginning, what you need is map trim key on your joystick. Now, before you take off, first move your stick (not the penis) and rudder and make sure that your collective is all the way down. It is just to recalibrate your input with game. Then trim your stick just to the right and down. This is your take off trim position.
You may need to engage heading autopilot. I do it, keep my life easier. Your mileage may vary. Raise your collective till you are at decent height, yell outloud "I'm coming biatches" and off you go :)
