What exectly would you check in somebody's first plane before taking it off? As I understand, it should be:

1. Engine needle valves tuning.
2. Prop balance.
3. Plane CG: head-tail and lateral balances.
4. All controls correct neutral position.
5. All controls "max" position (should reach the "max" position of the respective control but not more, right?)

Am I missing something?

Thanks.
