For Stu:

    I put the drain on the fuselage flange that sticks forward of the bottom
of the firewall.  If you make them from 1/4" tubing, cut off at about a
45-degree angle, and let them stick down about 1/2", you can then slot the
rear of the cowling to slide over them.  Then the drain tube will stick down
maybe 1/4" to 3/8" inch into the airstream.  In the manuals, they just say
to use a flush plate on the fuselage flange, and make a matching hole in the
cowling.  This means that any drainage will seep between the cowling and
fuselage flange, and then slime its way back along the belly.  Messy!

    I'm forwarding Eric Parlow's post about the (required) sniffle valve for
the IO-550 to the Lancair tech guys.  If I get any separate reply, I'll post
it here.

BTW, I've finished the installation of the TruTrak pitch and roll servo's in
my ES, so if anyone needs some advice on how not to do it, I have copious
notes.  I volunteered to work with Kirk Hammersmith and Jim Younkin
(TruTrak) as the ES guinea pig.  The installation came out a good bit
different than for the IV's, but in the end we worked out a nice, neat
installation that should be pretty easy for the next builders.
