Hi. An update on my balancing efforts.
What I wanted was an effective and systematic procedure to balance spinners and props both now and in the future. What I have done is probably good enough; although still miles away from what is possible with the equipment whether Du-Bro or Top Flite. I suppose I will get better with more time and experience of the tools.

Anyway, I enclose two images, one shows the chart of the spinner still unbalanced and the other the probably adequate balance.
Best wishes to all
Mike
