From: Richard Neilsen Nick Priority number one is getting the lowest trust line. Engine height for cooling is a consideration with a air cooled engine but most cooling problems are with ground operations and that goes away when airborne.

Keep the reports coming. Rick Lewis has been quiet for a long time is he still building? Haven't heard from Bob Green in a while. Any one else out there building VW powered Kolbs? I know there is at least one on the fence.

Nick C/Gang: I find the lower the engine and prop the better the performance. I have my 912ULS as low as it will go with about 1/4" clearance between the lowest point of the crankcase, the banjo fitting for the oil return line, can run a 72" prop and still have 3/4" clearance between prop tip and tail boom. john h mkIII Rock House, OR Thanks as always, Nick Cassara ________________________________ Message 4 _____________________________________ Time: 10:25:33 AM PST US Subject: Kolb-List: Re: Kolb VW From: "cspoke" Rick, My Xtra is heavy. 691 lbs empty.

My plane is 598 lbs empty but wet (oil and unusable fuel). That is with a full enclosure with storage pockets and coat of silver UV paint. I was real careful with weight. No more than three threads showing anywhere. That big 1-1.25 redrive bolt had 20 extra threads showing, not any more. If any part looked heaver than necessary it got lighting holes drilled in it. For example the diehel(sp) accessory case was designed as part of the difocal mount. That meant it is heaver than it needed to be the way we use it. It has maybe 30 half inch holes drilled in it in addition to the two mounting ears cut off. One of those holes is real handy to stick a screw driver into as a fly wheel lock. I also don't have a heavy magneto. My battery is a fairly light lawn mower 12 AH battery from Walmart. Not my idea, but a fraction of an ounce multiplied a thousand times in the build process adds up to be real weight. If it doesn't serve a purpose leave it off or cut it off. I wasn't even close on things because I didn't want to make anything weak. I'm sure I could get another 30-50 lbs off and not effect strength. Enjoy it the way it is but when you start putting a passenger in it, it will be over gross limit real quick.

Rich N has done an amazing job keeping the weight down on his plane. This winter I will see what I can do to reduce my planes "pork". I was suprised when I weighed mine. The pounds can add up fast. -------- Craig Spoke Mark 111 Xtra VW Redrive Lillian, AL cspoke@gulftel.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=315069#315069 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
