No, I'm still finishing my first. It's about to go into it's 9th year thismonth! However, we're about a third of the way through thte covering andall the structural work is done. The engine is on it's was and life isfood
. Should have the fabric done by the end of Nov and then it's onto the systems (what few there are). So far, the fabric has certainly beenthe most fun and most rewarding and the assembly of the fuselage structureranks second. As for the box, despite the new advances, I still have to mount it in theplane somewhere and a ply box is the best way to go, even if it's just toprotect the contacts from shorting out (the battery will be in the baggagecompartment area). Even these new batteries can still crack and there isalways the possibility of leaks so I'd prefer to be safe.KenOn Thu, 23 Sep 1999 mbell1(at)columbiaenergygroup.com wrote:> Ken,> > Are you building a second Christavia?
