RE: Cheap practice heli
Take your $200, invest in a flight sim. It will take you FAR beyond nose in hovering.
Flight sim was the best investment I ever made. It has helped my flying skill so much that I would not hesitate to suggest it to anyone, ever.
It might seem like a lot of money to spend on what is essentially a game, but the training value of the sim is invaluable, and so is the savings in preventable crashes.
Most modern sims are about as close to real life as you're going to get, which is great for training with your .30.
Some of the best sims out at the moment are Real Flight G3, Aerofly Professional Deluxe and Reflex XTR. All simulate helicopters very well.
