Whats up bro:
1. I never programed the shop button. Heck, I never made a shop. I was too lazy.
2. The helicopter crashes when you run out of fuel. You probably didn't collect any fuel, so crashed when the gas meter reached 0.
Well, first of all, why you not program it?
Second- I had enough fuel I did not run out of it still the helicopter crashes (sometimes).
