If budget permits, a simulator would be good aside from fixing your heli. I learned on a shuttle so quality of the base kit is not the issue, but maybe setup is. I suggest you do your hover training in a field with other heli flyers so they may guide you. The moment you can hover confidently on your own, you can probably continue learning again in the local park where you prefer.

Crashing sucks to be sure, but just suck it in and persevere, if you do, you will be greatly rewarded.
