This is Volume 6 of Ray's Authoritative DVD Series: Rotor Blade Building & Balancing.
This is the most influential helicopter DVD series you’ll ever see! We’ve made building rotor blades and balancing rotor systems a simple, straightforward process. A properly balanced rotor system is the “frosting on the cake” in terms of model helicopter setup. Learn how to effortlessly apply the frosting to the cake! Do you think your rotor head and blades are perfect out-of-the-box? Or that small electric helicopters don’t need rotor head balance? You might think differently after viewing this DVD. Don’t believe the line,”It’s balanced at the factory." Yes, it may be close (and then again, maybe not...), but it’s certainly not perfect! Learn how to make it perfect! When you truly understand what to look for as you balance a rotor head, you can balance ANY rotor system with absolute precision!
This disk starts with the core concepts of balance, and outlines four different balancing procedures. With the theory in hand, various places for error in the rotor head are discussed, and different types of corrective weight are shown. Then it’s on to building a perfect set of wooden rotor blades (for beginners), and balancing them to a high degree of precision with little more than common drinking glasses! The balance of the DVD features Carbon Fiber rotor blades (for intermediate/advanced pilots), and three other balancing methods. These use Du-Bro’s Tru-Spin balance, and gradually increase the degree of sophistication, culminating with an Ohuas gram scale and Miniature Aircraft’s Koll Rotor Pro. With the various balancing methods complete, that information is applied to the main rotor balance of a small electric helicopter. Finally, the DVD finishes by showing how to balance all types of tail rotors.
