Fly a RC Helicopter is a Challenge

Learning how to fly a r c helicopter is a challenge within itself, and could never be fully taught over the internet or through some book. The best way to learn is to get real flying experience with an instructor at first, and then on your own later. You can find an instructor at a local RC airplane and helicopter club. RC airplane clubs are most common and exist in just about every state and country, and since most of them will have experience with planes they most likely will also know how to fly RC model helicopters too.
In my opinion,the challenge beginner helicopter pilot's face is learning how to fly their chopper. This is a big problem since a helicopter is the hardest aerial vehicle to fly and having a miniature version of one doesn't make things easier. If you have no helicopter flying experience and you try to fly it, most likely it will crash into the ground. To save yourself frustration you need to learn how to properly put it together and fly it.
I recommend that you read the instruction manual, front to back, before you attempt to put it together and when you actually do, make sure you tighten every bolt and include every screw. One missing screw or loose bolt can throw the whole helicopter off and send it crashing to the ground because it is unbalanced.
