I'd very much appreciate counsel tempered by experience on the  

desireable thickness of aluminum sheet for the instrument sub-panels.



I've used some .040" 6061-T6 which was laying around, but I've  

concluded it's way too thin.



Many thanks,



Fred

Fred, .063 works fine in Baby Blue.  .080 is good, too, but heavier and, 

in my opinion, not necessary...

 I used .080"  (2mm) seemed about right . After I cut  all the holes there is not much left and the panels have to support a lot of  weight after they are populated.

I used 2mm too. Keep in mind that my panel is much larger than the

standard Europa panel; if it works for me it should work for you too. It

is true that after the holes are cut the panel appears weakened, but

populating the panel stiffens it up considerably. Actually it is more

rigid than before, as the instruments have less tendency to bend and

flex than the aluminium sheet itself.

I used one horizontal T-shaped stiffener reduxed in halfway down the

panel. The panel is strong enough to support all instruments, but I made

an additional support at the rear of my electrical gyro because of its

length and thus leverage.

I operate the Europa mainly from a bumpy soft field, transport the

Europa for every flight over the road on its trailer, so it sees a lot

of vibration and bumps. So far, after nearly 100 hours, the panel is

holding up very well with no signs of fatigue.

Fred,



If you want something with a real "cool factor" you can use carbon fiber sheet. Take a look at http://www.dragonplate.com/default.asp

Thanks to all who've responded to my question...wow!...the world of  

carbon fiber is something to behold...a tad spendy...easy to see why  

our airframes are FG instead of CF...looks like .080" alum. would  

serve me well...
