Congratulations, strat-- for me that came right after getting it out of the garage . It was really weird to have all that air around it, but then it clicked that it was ok to run into air, so I could try out more stuff! Flying up in the air is the first real orientation change, but it's a good one to make. You're safer 20 ft off the ground than 2, even if it doesn't feel that way at first.

Only real gotcha I can remember is that you can get in an orientation where the heli is sliding directly down toward you but since it isn't changing aspect, you don't notice it at first. Watch out if it starts getting gradually bigger!
