O.K. Just got off phone with guy who did work on the prop. He cannot believe that I lost ANY mph over the stock prop. He has never seen this??????? Anyways I have a BRAND NEW Bravo 1 26" headed my way. I will then do a back to back comparison of a stock prop versus the "labbed" prop. As I stated he is at a loss as to why I lost speed so I will prove it beyond any doubt against a stock prop. Then I'll see what he'll do for me.
