Almost finished in this pic. 0-1" mics in foreground for size reference. Started with a block of 2024-T4 aluminum 4"x4"x6". PTO Ass'y installed for test fit.

Pop can in picture for size reference. Again, finish grinding yet to be done.

Carl, Try the H667 from Octura. Same size and pitch (theoretically) as the 1667, but it is a MUCH more aggressive prop. As for the 21 Hawk, you can't go wrong with the ABC 1716. The 1714 and 1814 are also good starting points. Also try the Octura 1445 (pitched up), 1450 and the 1650 cut down...

Billy, I cut down the diameter on the 1657 to 55mm when I first switched for the 55 to the 57, but I now run it at full diameter. I do however "Barr-cut" it to reduce the load on the engine. Do not cup the 16xx props. If you can pull a cupped 1655, you should switch to the 1657. You can pitch...

Mark, NJ, others, We do keep returning to the 1.6 pitch ratio props because they are performing the way we like. The problem with the ABC props is the overly radical cup right at the trailing edge. This is only my opinion based on what I have seen and what I've been told that I agree with. I...

NJ, I have been testing with the 2116 and the 2118, both two and three blade versions. The 2116 is so far the better of the two, as it rev's higher, but I have not made any changes (cutting down, Barr-cut, etc...) so the jury is still out on the 2118. The 2216 is also a good choice. I have...

Kevin, :unsure: :huh: :blink: WOW......................! To the rest of the English speaking world, In order to reap anything from a supercharger or turbocharger, you must be able to contain the excess pressure within the cylinder until comustion takes place. Without some sort of...

Guys, Carburators operate through pressure differential. The high velocity of the air going through the venturi is at a lower than atmospheric pressure, causing the fuel to flow from the tank through the spraybar. If you "pressurize" the venturi, fuel draw decreases, causing the engine to run...
