Concerning flipping the 360, I found it much more satisfying to work on the 
landing gear and doors when the plane was inverted.  Cutting the doors out of 
the belly pan was easy when inverted.  Then it needs to be upright when 
drilling the holes for the plate on the aft spar (to set zero toe in and to 
get the leg vertical).  Also for installing the flanges on the surface 
against which the gear doors close.  Then it's much easier to work on the 
rest of the gear system (floxing the groove, installing hydraulic lines in 
the wheel well, and other stuff) when inverted.  So you might want to add an 
extra flip cycle.  Also, putting the firewall flange on (against the forward 
deck) is best done inverted.  Also, mounting a Bob Archer nav antenna in the 
roof.

I'd rather spring for coffee and donuts for the EAA chapter (or beer, 
depending on your chapter) to come over for five minutes and flip it, rather 
than struggle with the plane in the wrong orientation for several months.  
It's pretty easy to flip without an engine or tail.

Concerning the forward CG issue (should I switch to the extended mount, where 
should I put the gear pump ... ) -- I'm not an expert since I've only flown 
in two Lancairs.  The one with the more forward CG, specifically Orin's plane 
which was used to establish the new forward CG limit, is a delightful flying 
machine.  The other one had an aft CG and was downright scary to fly!

I'm doing everything possible to get my CG forward.  Everything.  The worst 
thing that could happen is that I overdo it and might have to add a pound of 
lead to the tailcone but I'd bet almost anything that it won't be necessary.

Don't take my word for it.  Fly in a couple of Lancairs and see for yourself.
