basic flying questions for newb

[ARGH]

please explain;

1] engine management during flight.

2] how to start the engine.

3] what controls should be assigned to a flightstick system.

4] why doesn't the bf109's flaps work.

5] i cannot assign a weapon loadout in a quick mission, only defualt or empty.

6] sometimes i cannot assign a different plane in a quick mission, just reverts to default plane.

answers don't have to be complex. i think it is best to ask in forums instead of spending another 3 hours trying to figure out what control settings do and assigning them to the G940.
