First, Welcome to the frey.

Yes, the blades will still fly as Georges says. For ballancing blades, do a "Search" on here and you'll quickly find good instructions on that process.

Many on here, including myself have used [link=http://www.dream-models.com/eco/flying-index.html]"RADDS School of Rotory Flight"[/link] which is an online step by step flight plan for learning to fly rc heli's while minimizing crashes and broken parts. I highly recommend it and the concept of keeping it simply, being patient and practicing one thing till your bored before going on the the next move. It takes many many battery charges to get through but it works. Best thing is it gives you a flight plan...a goal before you even plug things in. Having a plan or routine that you practice over and over, and simply add new things to as you get better, is a great way to go.

Happy landings
