We recently received an article for our magazine where the author performed
a balance of his tail rotor on a bench using an electric motor and a dial
indicator instead of an electronic balancer. I was impressed with his
thinking outside the box. If there is any interest in this out there, I
will see if the author would be willing to discuss his technique here.
