Another suggestion for the sub floor:

If you use the adjustable pedals, add a stiffener
left to right under the deck around the mid point.
 I had the original  adjustable pedal set and switched
 to the newer set when I switched to the newer brakes.
I found without the stiffener the floor flexed whenever
I applied rudder force, with the stiffener it vastly
improved.  Just a scrap of prepreg bonded  to the
fuselage bottom and fit it by sanding it down.  A layer
of mircro with some flox in it bonds it to the bottom
of the sub floor.

Don't forget to put some sound proofing foam
especially under the pilots side.  That is where the
exhaust port is and any sound proofing goes a long
way to cabin comfort.

I have six hours on the aircraft now, and my test pilot
remarked about 5 times how quiet the cabin is during
his solo first flight.

I spent 4 hours with Don Goetz in the right hand
seat on Wednesday.  My ex-project, now aircraft, is
flying straight and according to Don "very smooth".
I am still in the very early phases of flight testing but
I was getting 178kts indicated at 24psi/24500rpm at
6,000ft.  Don's landing technique is a bear to get use to
 and I am still not comfortable enough to solo.

Are there any CFI's out there with at least 2 hours of time
in LNC2's near Santa Rosa that could offer me some
dual time?
