.....
In order to provide a leak proof seal around the main fuel tank
after installation, small stiffeners are placed along the fuselage
sides so that, when installed, the main fuel tank will set down on
these stiffeners, thus assuring good squeeze out of the flox and a
good seal. These stiffeners are nominally of 1/411 square cross
section, and made from the thin sheets of white foam. They are
positioned by dry fitting the fuel tank in place, tracing around the
main fuel tank on the fuselage side, and then lowering the traced
lines the thickness of the main fuel tank after removing the tank.
The stiffeners are installed with flox, and allowed to cure
completely prior to mounting the main fuel tank permanently. Do not
be concerned at the number of separate stiffeners required to cover
the tank perimeter.
.....
To install the main fuel tank permanently, it will first be
necessary to notch the forward lower edge of the main fuel tank at
BLOO so that the fuel line tubing will exit the tank there. Next, mix
up both pure epoxy and flox. Paint pure epoxy liberally on all
exposed areas of the stiffeners, to prevent contamination of the fuel
later. Trough flox liberally on the top of the stiffeners, as well as
on the fuselage bottom where the forward and aft edges of the main
fuel tank will rest upon assembly. Next, trough flox around the edges
of the main fuel tank that will come into contact with either the
stiffeners or the fuselage.
.....
Insert the tank in place, and verify that you have good squeeze
out of the flox everywhere to assure a good seal. Wipe off the excess
flox on the top side as you make a flox radius between the tank and
the fuselage. Laminate 2 BID tapes with a 111 minimum overlap to join
the man fuel tank to the fuselage. Liberally apply flox around the
exit of the fuel line to prevent leaks.
SEATBELT ATTACHMENTS

A very important safety feature of your Q2 is the individual
seatbelt/shoulder harness assembly provided for each occupant.
