GUIDE FOR BEGINNERS

Preparing for the Great Adventure

Flying a Model Helicopter is rewarding, but rewards only comes with dedication and patience. If you want to go out and buy a helicopter, fix it in one day, and then zip around the sky like an expert the next day, then helicopter flying isn't for you.

Cost is another great factor to consider. This hobby is by no means cheap. Crashes will happen, and when it does, you'll be spending several dollars to several hundreds on repairs and spares. You have to be mentally prepared to put that amount of money aside for the rainy days.

Lastly, flying a model helicopter is safe only if you are safe. The rotating main blades of the helicopter spins at 1500 rpm, with a blade radius of about 1 meter. The speed of the blade tip is roughly 200 mph! At that speed, it will easily cut thru grass, skin and bones. Never fly a model helicopter until you are completely and definitely sure that you will be able to control the helicopter. And in the event that you loose control, no one, including yourself, is in the way of the ravaging loose runaway helicopter.

Register your radio with your local telcommunication authorities, and get some form of insurance coverage if your model were to hit other people's property or life.

All these small precautions will put your mind at ease and you can then fully enjoy the trill of learning, building, and flying the most sophisticated radio control model every designed - The RC Model Helicopter! It's time to get into RC Helifever! – Taken from: RC Helifever
