There is a much better jump down at the end of the football pitch, but didn't seem we could keep more than 1 or 2 cars running, so everyone just stayed at what was the "pits" and destroyed grass there
Flipping a heli... best advice is do stall turns and each time you get confortable pull up a little further until you are beyond vertical. Nothing changes in the maneuver, even beyond vertical you just kick the tail round and pull out. Then go a little further and finally just don't let go of back as you go up the stall turn. Remember to pull in some negative (for the first one, smoothly put a load in so you gain height instead of lose it). Then just pull on out

One loop.
Once you get comfortable with those and the negative pitch pulse, you can do them stationary.
