Twenty (US) gallons each, all
aluminum construction. Salient features of the installation are
simplicity of the mounting of the tank which requires no rework
of the wing or control surfaces whatsoever. The Tip Tank
aluminum mounting flange (wing attach point) used exceeds .060”
The aluminum material guards against finish paint color fade and
shade changes. Waviness (humps) between attach mounting screw
points will never occur, even long after installation. With
aluminum construction the mounting flange makes a quality
transition from the Tip Tank to the wing, fitting like a glove.
Two lateral holes are predrilled for installation ease and
convenience. But more importantly this assures a parallel fit
and alignment to the centerline of the airplane. These
predrilled mounting holes simplify mounting and help the
drilling of remaining mounting flange holes. Thus saving flange
mounting hole layout time. Low profile washer head screws are
provided, however the thickness of this aluminum mounting flange
will accept, and is FAA approved for flush head type screws.
No rework or modifications of the factory wingtip nutplates are
necessary. The Tip Tank mounting installation utilizes the
When installing a Tip Tank kit, control surfaces in particular
the ailerons are not required to be removed and rebalanced. As
some other airframe modifications require.
A series of 10 each strength stiffeners (ribs) are welded to the
skin of each tank. They also double as baffles.
Fuel filters are provided in the Fuel System(s) (excluding
existing factory filters), only one filter is used in replacing
the factory selector valve with the 5 way valve (direct feed
system), complementing the aluminum design.
No electrical grounding of the Tip Tank is required. This is
because the Tip Tank is aluminum, the same as the Navion factory
Wing Tip Fairings.
Increase in wing span after Tip Tank installation is negligible;
due to the tanks replacing the factory wing tip fairing width
