Hi John,
I ran my vent line from the top of the tank to the top of the
fuel filler moulding. I changed the vent line from the dinky 1/4" line
to a 1/2" line. This lets the top of the tank fill rapidly by being
able to vent the air out to make room for the fuel. From the top of the
fuel filler moulding I ran a 1/4" line up to the top of the fuselage and
did a 180 degree turn and ran it back down along side of the fuel
moulding and into the area under the baggage compartment. From there I
ran it over to a point just behind the flap unit. I reduxed a stainless
steel tube (that Europa provides for venting) that I bent to a 90 degree
angle and faced it forward. I did the back drilling to protect it from a
bug getting stuck in the front. By placing it behind the flap hinge unit
on the bottom you get a natural blocking of critters before they get to
the vent line. Keeps all possible gas dribbles out the bottom.
Actually with this system, I get no gas out the bottom as the top of the
fuel moulding provides the vacuum break necessary.
I broke down and bought Tru-Trak's smallest wing leveler(~$1700).
I am installing it as our little fighter needs to keep the right side up
while I'm looking at maps and GPS's while navigating around the area. The
aircraft is very sensitive and if I let it alone, it will head to where
the green things get bigger. It trims out nicely but gusts of wind ect
will disturb the equilibrium and I'll drift off and drop a wing. The
leveler will track a gps heading I'm told so if its there, I guess I'll
hook it up. I really need only the leveling function.
