I've the same balancer. I should at least give it a try and see how far out of balance I am (the plane not me). Really though, in flight it feels smooth, it's just that if there is something to be tweaked (in a good way) why spend my time flying when I can find a reason to be wrenching. Ha.

Today I dusted off the DyaVibe installed two new 9v batteries. I really didn't 'feel' like doing a balance job since it all felt ok to me. I'm glad I did. The prop bolts have a diameter of only 4-3/8" so I was skeptical. The work started with the prop at 0.27 IPS (Inches Per Second) which is not awful. But by the time it balanced to 0.01 IPS the difference was noticeable. This should keep various parts happy longer. It just feels good to know how well balanced the prop now is instead of guessing.

Brock,

You´re a better man than me! With a prop bolt DIAMETER of only 4-3/8 in, I´m surprised you managed to balance anything at all :-)

Exactly! I didn't think it would work but in the end it was quite simple and worth the effort.
