BVM is always interested in the future of jet model
airplanes and how to make our current products even
The fuel supply system for larger turbine powered models
is our latest area of this "improved" interest. While
our current system has been working well for several
years, it has been noticed that it can be sensitive to
installation error and certain engine fuel pump
Thus the BVM Hi-Flow Fuel System
Every component, from the Brass Clunks in the tanks to
the fittings on the U.A.T. have been made larger. This
includes: elbows, tubing, "T's", over flow fittings; as
we stated, "Everything"!
A side-by-side bench test of our standard system against
the new Hi-Flow system, demonstrated 1/3rd of the
fuel flow resistance.
Subject model was a BVM Ultra Bandit with the 6.2 liter
fuel tanks and a JetCat P-200.
System demand was measured by applying a vacuum gage to
the fill fitting on the U.A.T.
With this whopping extra margin of "eased" fuel flow,
the system can now even tolerate bits of junk like filings, or dirt in the fuel tanks,
without impeding engine operation. The engine fuel pump
power demands are reduced, adding service life to this
critical item. There will be no combination of throttle
movement vs. aerobatic maneuver that can exceed the
Hi-Flow system's supply capability.
What Engines Need The Hi-Flow System?
Certainly, turbine engines in the 180 class (40+ Lbs) of
thrust or larger will benefit from the Hi-Flow system.
Like all BVM
Jets products, the Hi-Flow Fuel System has been
thoroughly flight tested.
