Welcome to this crazy world of trying to fly Heli's. That will be your first month. Trying to learn to hover. What ever you do, stick with it for the first month. It gets REAL! fun after you can hover. It sounds like you are on your way. GOOD!

Lipo's are your first and best upgrade while learning. You can get 15 minutes of "learning" out of a 910Mha pack. Even more out of a better pack. Stock batteries offer about 5 minutes, then an hour of charging. You should have 3 batteries to maximize learning and charging time. After 2 or 3 minutes pf hovering you just might be on brain over-load. This will get better. But having battery power in reserve gives you a chance to swap batteries right away and keep on learning, well that is if you don't crash (and you will, crash).

My personal favorite as far as chargers, balancers, and batteries is: Thunder Power, they are more expensive, but I have never had a failer with them.

If there is anyway that you can get some Simulator time you will learn much faster. A bout 10 hours on any sim and you will be ready to hover. Look in to it.
