Europa-List: Prop Balance

[Richard Lamprey <lamprey@infocom.co.ug>]

Jeff, you are very welcome.  I cant say that I can claim the credit for 
this, I read about it somewhere many years ago.  It is the fibre-'seam' 
in the spinner that seems to cause most the inbalance, so the 
counter-weight will lie somewhere opposite from this.  Of course it is 
quite challenging to get the spinner to float or lie in the water (with 
its holes), but a good idea can be had about the imbalance, and a lot 
cheaper and more convenient than dynamic balancing.

All best
