Nice prop but this is slower off the line. Takes a couple seconds to get up on plain , stock M41 is faster out of the hole but not a fast on top end,and the plastic one break to easy.

bullet and nut are not bad but brass prop is a complete waste coming in over 4 times heavier at 9 grams!!!, this kills the performance/speed and over works the motor, have tested many and stock plastic one is still the best performer by far and weighs in at 2 grams

Original plastic on my Spartan is faster 49mph. Bends easily, also vibrates violently at top RPM, something is out of balance.

I went from a stock plastic 42x59mm prop to this 42x63mm prop and man it moves, well worth the money.
