EVF 4010/5612 Fan Units
The Electric VioFan is presented to the customer in a completely assembled and test run format. Series 4010 defines this unit as a 4000W system designed to work with 10S Lithium Polymer cells in series. Series 5612 defines the unit as a 5600W system designed to work with 12S cells and castle Creation 140SHV speed controller. The power yield all units is approximately +14 lbs. (6350g) to +20 lbs. (9080g) of thrust on an 85F degree day at sea level. This is bench tested static thrust using a bell mouth inlet and no tailpipe. There will be installation losses when the EVF is used in a model. These losses will vary according to the inlet and tailpipe design of the model.

A Little History...
The original BVM ducted fan system, the "Viojett" was designed by aerospace propulsion engineer Lee Anderson in 1981 and was the core product in the early days of Bob Violett Models Inc. Several sport and scale jets were developed around the Viojett. Originally powered by a high performance .72 cu. in. K&B engine, the power evolved to the BVM .91 and .96 cu. in. piston engines. For a period of 15 years, the Viojett reigned untouched in the performance arena. Viojett powered scale replicas of the F-86, F-80, T-33 and F-16 won many major scale competitions such as Top Gun, U.S. Scale Masters and the U.S. Nationals. The Viojett design allowed scale size inlets and exhaust nozzles unlike any other available fan unit. The high performance speed contests were always won by the Viojett in a Viper or Aggressor model. The advent of the micro turbine engines into model aviation soon replaced the piston engine driven fan. The turbine offered more power, realistic sound and more reliable operation.

The BVM EVF Advantages
A great "jet like" sound, almost turbine, and much more realistic than piston power or the high squeal of some other very high RPM EDF's. A solid, self centering rotor-to-motor shaft mounting with factory balanced rotor. Super cool operation for the motor and Castle Creations controller. Streamlined exit of electrical wires from the duct, vibration free operation, rigid carbon fiber and aluminum construction. One source for the complete power system and charging equipment. Factory assembled and test run, ready to install in your model. Multiple battery options to fit your model and desired flight profile as well as complete set of instructions to introduce you to Electric VioFan power for your jet.
