"Ultimate Air Trap" (U.A.T.)
A BVM Exclusive

U.A.T. Update - hints/tips on first time usage

We now have well over 500 flights on various factory demo models that use the U.A.T. We tried every possible maneuver and unusual attitude combined with every possible throttle position - you just can't make it quit!

All BVM fuel cell packages (for BVM jets) now come standard with a U.A.T.

The mystery material, duck bill shaped sack inside will deliver a solid stream of fuel (no bubbles) to the fuel pump even if the 4oz bottle should get 3/4th's full of air, which is very unlikely.
This is a very high quality product for those turbine pilots who want to eliminate the possibility of an air bubble causing a flame out. The U.A.T. is placed in series between the last fuel tank and the fuel pump. The system is filled through the 3rd line in the U.A.T.
The rectangular shaped tank can be mounted vertically or horizontally and produce the same results making it convenient to fit into just about any model and it will work with any model size turbine engine.

MORE GREAT NEWS ABOUT THE U.A.T.

The U.A.T. is also a great filter eliminating the need for another filter and its two connections in the system.
The fuel "in" nipples are custom machined from brass for a very snug fit to the 6mm urethane fuel line. The fuel "out" connection is a Festo compression fitting.
Another super advantage of adding a U.A.T. to your fuel system is that all of the fuel in your other tanks is now completely usable, (assuming the clunks can reach it).
Formerly if we had a 16oz header tank installed you couldn't count on using the last 8oz - now you can. Don't plan on it, but 3oz of the 4oz in the U.A.T. is also usable.

The U.A.T. may also be used with gasoline engines. Developer Jeff Seymour has been flying one in a large gas powered model for some time. U.A.T.'s should work with any pump equipped engine. It has not been tested in a ducted fan installation.

Here is a recent letter from a Mike Danchak, a customer from Texas that informed us on the use of the U.A.T. on a glow engine.

We think that this is one of those "very significant" developments that come along only occoasionally in model airplane technology. Congratulations to Jeff Seymour of S.W.B.
The unit comes completely assembled and ready to install in your jet.

Retail price is $65.95.
