I have a background in high-performance (1:1)outboard boats, so I already have some knowledge in prop physics I can apply to the RC world. I just got a new PB Blackjack 29, and a stock extra prop. I decided to work my spare prop a bit... I removed most of the casting flaws, thinned the blades a bit, and squared the trailing edge. I ordered a balancer to finish the job right. . So far, it's at 8 grams, a quarter-gram lighter than my stock prop.
Here's the stock prop for the "before"...
And the "after"...
Am I on the right track?
