The first model – (submersible pump model) – is set in the fuel tank of the aircraft.
The second model – is connected to the airframe fuel pipe as an auxiliary pump.
The FPC2 unit controls initiation and revolutions of brushless engine. It is intended for non-stop performance. The unit allows setting up, monitoring and storage of operation parameters.
