What is the difference between them? Can -L2C cylinders be used on the -C2C engine in the AA1B? -Dj -- Dj Merrill - N1JOV Glastar Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Please use Netiquette Guidelines http://tools.ietf.org/html/rfc1855 Kindly TRIM your email replies and post AFTER the relevant text ________________________________ Message 2 _____________________________________ Time: 09:20:09 PM PST US From: Gary Vogt Subject: TeamGrumman-List: Engine Thrust Angle: Page four If, for all practical purposes, I get a zero thrust angle (vertical) with 2 shims on the top of both mounts on my Tiger, maybe the factory's zero thrust angle (vertical) is based on the wing's incidence angle and not the level fuselage. Just an idea. Just for shit-n-grins, I checked two other planes today. Plane #1: (Project X Tiger) 1 shim on each mount. Using the same inclinometer I measured at the rails at left rail: 4 degrees up. right rail: 4 degrees up. On the engine, measuring the angles left side: 3.5 degrees up right side: between 3.5 and 4 degrees up. The distance to the spinner was the same as mine: 39.875 inches. Bottom line: not much difference between the airframe and the engine. ==================================================== Plane #2: (Cheetah) 2 shims upper right. 1 shim lower right. No shims on either of the two left mounts. left rail: 2.5-3 degrees up right rail 2.5-3 degrees up left engine: 2.5-3 degrees up right engine: 2.5-3 degrees up. The distance to the spinner was: 39.75 inches. Bottom line: the engine sits about 1 degree down. I've included a pic of this. The engine needs a 1/2 shim on the bottom mounts ==================================================== Interesting thing on the AG5B Project X plane. The cowling is 3/8 inches low with all the screws in but not tight. It's also off to the left a little. Pushed up and to the right and then tightening the screws, it's more centered. I did notice that the cowling behind the spinner is a smaller diameter than the spinner. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message teamgrumman-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/TeamGrumman-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/teamgrumman-list Browse Digests http://www.matronics.com/digest/teamgrumman-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.
