Run in fast and high. Don't yank the stick back. Pull it smoothly into the vertical. If you still have speed as it is pointing nose to the sky then keep pulling. If you don't, then 'stall turn' out of it.

Lower the collective over the top but don't go mad. Keep pulling back and there you have it.

Think of the 'bail outs'. The first one is the stall turn in the vertical. As you are inverted it is more tricky. If you can roll, then a half roll out is an option. Otherwise the most likely the only option from here is to keep pulling. That is where the extra height for safety comes in!

Once you have done it a couple of times you will probably find that it is not that hard.

Good luck.
