There is an automatic "squelch button" of sorts for the Fund Raiser messages. Here's how it works... As soon as a List member makes a Contribution through the Matronics Fund Raiser web site, their email address is automatically added to this year's Contributor List and they instantly cease to receive further Fund Raiser messages for the rest of the month! Its just that simple! :-) I really do appreciate each and every one of your individual Contributions to support the Lists. It is your support that enables me to upgrade the hardware and software that are required to run a List Site such as this one. It also goes to pay for the commercial-grade Internet connection and to pay the huge electric bill to keep the computer gear running and the air conditioner powered on. I run all of the Matronics Email List and Forums sites here locally which allows me to control and monitor every aspect of the system for the utmost in reliably and performance. Your personal Contribution matters because, when combined with other Listers such as yourself, it pays the bills to keep this site up and running. I accept exactly ZERO advertising dollars for the Matronics Lists sites. I can't stand the pop-up ads and all other commercials that are so prevalent on the Internet these days and I particularly don't want to have it on my Email List sites. If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email Lists, please make a Contribution to keep it that way!! http://www.matronics.com/contribution or, you can send a personal check to the following address: Matronics / Matt Dralle 581 Jeannie Way Livermore, CA 94550 Thank you!

I am personally biased towards Woodcomp, but having said that I have been impressed by the claims of DUC although have also heard rumours about the relative frailty of the blades.

I fly a LongEZ which is really limited by the fact that it can only be fitted with a fixed pitch wood prop.

One is a WoodComp and another is a DUC. He wants to sell them to me quite inexpensively. But I don't want both so just need to decide if I should get the DUC or the WoodComp. I don't like the way the DUC looks (narrow chord) but if all the hoopla about its "constant speed" characteristics is true then maybe is worth consideration. I am hoping some forum members may have experience with the DUC to share. > > Thanks, > Chris > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=484767#484767 [1] > Links: ------ [1] http://forums.matronics.com/viewtopic.php?p=484767#484767 [2] http://www.mypilotstore.com [3] http://www.matronics.com/contribution [4] http://www.matronics.com/Navigator?Europa-List [5] http://forums.matronics.com [6] http://wiki.matronics.com ________________________________ Message 3 _____________________________________ Time: 03:09:57 AM PST US From: roger cullum Subject: Europa-List: Suitable prop for my Europa project Hi All , I am building a trigear Europa and wish to fit a ground adjustable second hand prop, Motor is 912s .
