I have a 10+ pound survival/tool kit on the rear baggage shelf that brings the CG inside the forward limit when solo. When solo however I tend to also put a case of oil in rear luggage compartment, unless of course I have other stuff to haul. The good news is I have had some real beefy boys in the back and the CG was still well within limits. At some point I may move one of the two batteries aft if I am taking the plane down for some other major modification. This is certainly not an operational problem. For all other 8A builders using a parallel valve (I)O-360, recommend you consider mounting your battery aft, or if you are a two battery ship one battery aft and perhaps the other in the forward baggage compartment well. Carl Froehlich RV-8A (450 hrs) RV-10 (fuselage) From: owner-rv-list-server@matronics.com [mailto:owner-rv-list-server@matronics.com] On Behalf Of Craig Gallenbach Sent: Thursday, October 02, 2008 6:56 PM Subject: RV-List: RV8A Weight and balance I weighed my RV8A and was somewhat surprised at the results. I have a Superior O-360 normally aspirated engine, Sensenich fixed pitch propeller, and forward mounted lightweight battery. The empty weight worked out to 1080 lb with a CG at 74.8" (as measured using a datum 70" forward of the leading edge). With only the pilot (220 lb) on board, I need between 20 and 30 lb of ballast in the rear baggage compartment to be within the acceptable CG with maximum or minimum fuel respectively. Is this typical for an 8A? With a fixed pitch propeller and lightweight battery I was expecting to be not quite so nose heavy. Have others had similar results? Thanks in advance for your help.

I thought some might be interested in seeing exactly what the Grove Aluminum Airfoiled landing gear for the RV-8 look like. They are a work of art! Very beautiful indeed. Notice the predrilled holes for the brake lines. They're not cheap, but they are really very nice. The weight savings forward of the CG is certainly something to consider as well. Any any decrease in fiberglass work is worth the price of admission, in my book... ;-) Best regards, Matt Dralle RV-8 #82880 ________________________________ Message 5 _____________________________________ Time: 07:26:35 PM PST US From: "RALPH HOOVER" Subject: RV-List: Bakerseal Or EZTurn? "What are the pros and cons of Bakerseal vs. EZTurn for installing all of the AN Blue fittings?" Matt, I have used both EZ-Turn and Fuel Lube on AN fittings. The fuel lines appear to be leak free, not true for the brake lines. I will now try Loctite 567 on the brake fittings. Report to follow!! Ralph & Laura Hoover RV7A N527LR Very very close!! ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-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/rv-list Browse Digests http://www.matronics.com/digest/rv-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.
