The k42 was the first prop that I test. Before the 642 which is why I couldn't understand how the log showed 7.7 v at 30 amps with the 642.

And 7.4v at 24.6 amps with the k42 when that was the first prop that I test.

The aquacraft was 7.4v at just over 23amps with the k42.

7.2v with the 642.

The truth is the 4092 does push my boat like 9 mph faster on 4s with a m545. When compared to the aquacraft with the same prop on 4s.

And I am referring to the same 1730 rated leopard 4092.

I have the 2080 rated kV 4092 leopard and that is like 5mph faster than the 1730 rated 4092 same prop.

So the 2080 is like 14 mph faster than the aquacraft 4s for the leopard and 4s for the aquacraft.

These 4092's is monster 4s motors.
