lined up for takeoff and had to shut
down the turbine when the model
failed to accelerate when throttle was
applied. I have also seen pilots neglect
to shut down the turbine in time, and
the tailpipe failed from the excess heat,
destroying the beautiful jet model.
My Xtreme ARF Vixen Sport Jet
has an Intairco High Flow Air Trap
Tank. It is an attractive piece, with
the red anodized aluminum end caps
surrounding a clear tube to form the
tank. The clear tank makes it easy to
see the fuel and air should you have
problems with the tank that is feeding
this air trap.
The tank has four fittings—two are on
the top for feeding from up to two tanks.
In the air trap tank installation in my
Vixen, both feed directly from each of
the left and right saddle tanks, and then
the fuel pump is fed from the middle
with a metallic filter inside of the air
trap. The fill/drain line is at the bottom
of this air trap, allowing it to be drained
when the tanks are emptied at the end
of a day of flying.
One impressive part of the Intairco
High Flow Air Trap Tank is where the
ports are located on the fuel inlet lines.
They are at the top of the tank. When
filling the tanks, visible air remains in the
air trap, which is nice.
At the end of the flight, any air in the
air trap will be from the tanks that are
feeding the air trap. Look for problems
in those tanks when you see an excessive
air bubble lodged in the air trap.
The Intairco High Flow Air Trap Tank
has large fittings, allowing the use of the
larger-diameter fuel tubing that supplies
kerosene to our turbines. Overall, it’s a
nice package, and a well thought out and
executed product that can also add some
bling to your next installation.
