That sounds right David, That factor reminds me of trying to gain speed.
40% more power may result in 18% more speed .
That can be a money
pit for many toys, and lead to other problems.
Why is it fun for us to do that ?
I have bad habit, if its a 3 HP trolling motor
, or a motorcycle,
A guy wonders what makes it go faster. I have spent many days making prop shapes to improve efficiency, but never gained much. I made a mold
to make aluminum
prop blades , it was a pain to get it right.
I like the purity of Sailing and Flying something underpowered,
then your down to the Art of it.
