Don't get discouraged. I just got into helicopters myself. It is probably one of the most difficult RC platform I have ever tried. They look cool and it looks easy when someone else does it. I bought a G2 just before X-mas and did what is probably the most common and first mistake new heli pilots make and thought I knew how to fly. I crashed pretty hard once and after that the esc went. While I was waiting for parts I picked up a used blade 400 for cheap from a friend. I thought to myself, I am not going to screw this up again. I found RADD's school of rotary flight.
Follow this to the T and you will be hovering in ten practice sessions. I learned to hover on the blade, and now the G2 is actually a pleasure to hover. I can hover for a full pack without any problems and no training gear. Print out the instructions and follow them it will save time and money. Getting a better battery will extend flight time, and it will add weight to the nose of the bird. When you practice it needs to be somewhere you can concentrate and no pets it the area. Almost lost my dog the first time I spooled up. You wouldn't walk on to an airfield and hop into a chopper by yourself and expect to live, kind of the same idea. I have learned that patience is cheaper than anxiousness when it comes to helicopters. First upgrade should be the servos, what a difference.
