Europa-List: What else to stuff in wings before bonding on top?

[Ronald J. Parigoris <rparigor@suffolk.lib.ny.us>]

I figure there is too much "Atmosphere" inside my wings, and am trying to find
things to fill up the voids.

So far:

wires and a tube to power tip strobes/nav lights

wires to outrigger fairing in case I want to put landing lights in the fairing

stall warner

airspeed/pitot

Any other useful things you can think of?

Antennas?

Thanks
