Get a sim and pracrice till your fingers fall off!!!
Its worth the effort it really is, rc helis are hard to fly and the little feller that you just bought will be lightning fast in how it handles...small electrics are notorious for it.
Make sure that you have access to spare parts, and yes...and decent charger and batteries is a great idea...dont forget the radio batterys too...buu some rechargables for that and make sure to monitor the power level...DONT fly if the battery state isnt good...you WILL crash.
Make sure to use the training legs...or better still make a hoop out of plastic tubing...make it the same diameter as the rotor....fasten using cane and elastic to the skids...makes a good base to stop the heli from tipping over and getting wrecked quickly.
