If you are gonna try and fly it m8,get some help/advice from a local club or experienced modeller first cos they can be absolutely deadly in the wrong hands(every year at least 2 people are killed in uk by radio controlled models !!!!!).

If you are seriously interested why not join a club or something and have a proper go........its very rewarding......but be warned flying a heli is like trying to balance a ball bearing in the middle of a dinnerplate with a raised centre(and thats a modern one with gyro etc !!!)
