If light air speed is not important to you however that would be a good choice for performance under power. |

I think we got ours from PYI http://www.pyiinc.com/ MaxProp themselves are at http://www.max-prop.com/ You might try http://www.vicprop.com/sales.htm who are in Canada and say they handle the MaxProp. I don't think you will get an extra punch in fwd. As I understand it (and I may be wrong), the reason that you get more reverse is that the prop paddles are not 'cupped' or angled like the fixed prop ones are, but are flat. The cupping is for maximum performance in forward gear, and it makes reverse less efficient. If you have a flat prop, then it is equally good in both directions. grandma Rosalie S/V RosalieAnn, Leonardtown, MD CSY 44 WO #156 http://home.mindspring.com/~gmbeasley/id2.html |

The MaxProp turns the blade when reversing, presenting the same "forward" edge of the blades in both forward and reverse, thus providing a very good thrust also in reverse since there is no compromise between fwd and reverse efficiency in the blade design. IMO, the only "better" prop than MaxProp is the Gori folding-feathering (or what to call it), but that's even more expensive. /Marcus -- Marcus AAkesson Gothenburg Callsigns: SM6XFN & SB4779 Sweden Keep the world clean - no HTML in news or mail ! |

The "1/2 the price of the engine" came from the quote I got for an AutoProp: $3K. And the engine is about $6K (About $8500 CDN). Another poster gave what I believe is a good site. Yell if that isn't good enough (BTW: I'm not really concerned with reverse - after nearly 15 yrs, I've gotten used to Far Cove's propwalk and use it to my advantage. But extra punch in fwd would be nice!) I don't think you'll get better punch in forward unless you're switching from 2 to 3 blades or to a larger diameter, as the MaxProp isn't optimized for forward though it isn't horrible. Performance in reverse is an amazing improvement though. You have to experience it to believe the difference. We spin on our axis so easily that we've never actually *needed* an authoritative reverse to get unstuck, but we haven't needed to spin to get ungrounded since we switched. ('Course, that could be because I've learned not to get as stuck.) Our switch was from 15"x2 blade to 16"x3, so we can pull stumps if we need to, and our reverse power is only slightly less than forward. -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |

The Luke is nice because its geometry is pretty much identical
to a fixed prop in fwd and rev. No poor performance in rev like some feathering or folding props. Doug "Jere Lull" wrote in message ...

Agreed. My Luke prop has the exact configuration of a fixed prop
when in fwd or rev. No degradation in reverse. Feathers well too.
