Currently, I've replaced the 80 pound gill battery with 2 oddesy's up top in the old battery box. Before making the change, there was 55pounds in the tool box, 40 pounds in the IFF area, and the 80 pound gill. It feels nose heavy compared to my other l29, and another one I have flown. The new config, removed the 55 out of the box, and the new oddysey's and the wiring adds up to about 53. negligible change. We looked at he way the w&b was done, and the datum used appears to be the nose wheel center. That puts almost 200 pounds in the "negative" of the w&b calc. We looked in the book and the diagrams are difficult to read, but it would seem the datum is at the nose cone tip, or at the bulkhead right behind it. My question, anyone know the approved area for the datum? thanks Skidmk -------- Mike "Skidmk" Bourget Ottawa, Ontario Read this topic online here: http://forums.matronics.com/viewtopic.php?p=458131#458131 ________________________________ Message 2 _____________________________________ Time: 01:05:33 PM PST US From: Robert Schwartz Subject: Re: L29-List: weight and balance question R model or c? =C2- =C2-Tool box??

Is the IFF unit still in the compartment . If not what if anything is there. Original battery compartment was in left top shelf in nose adjacent to oxygen bottles. Are bottles still there? You eluded to making battery compartment into a tool box. Where then is the battery now. On July 13, 2016 16:05:12 "skidmk" wrote: > > sorry for those I"ve confused. To keep it simple.
