Ah! found them! the props I've been testing took about 2 months of running and with a cheap budget these props fell into line, and with the big help of Ken2 @ prop gods I found the prop. I would like to go for the 15 X 15 enertia that would give the best of all worlds for the boat, but it was out of my price range. One day I'll get it and use the Apollo as a spare.
