Good point. Even single blade racing props are balanced, but it takes more mass at the hub to do so.

A1pc,

It's not about embracing or rejecting change. It's more about making the determination that any given change is for the better, or provides greater value than what had gone before. For the terminally lazy or the uneducated, the Vess ring is a hot ticket. For those that are willing to expend the same amount of time but have the knowledge to perform the task, it's not worth the investement. Each has to make the decision based upon the amount of information and experience they have.

So I have yet to say the Vess balance ring is a waste of time and money because for some, and I will agree those will generally be people that have grown up with arfs, it a good deal. For people with experience, and builders that understand how things work, it's not such a great deal. Everyone that uses one will be paying extra for something that is really uneccessary since the same end result can be obtained without the Vess ring. I suppose it depends whether or not someone is a modeler or someone that can only assemble bolt on components to achieve a goal. The two types are quite different in their abilities.
