The phrase refers to the process of connecting two electric ducted fan (EDF) units to a power source and control system in a radio-controlled (RC) aircraft. This involves correctly linking the motors, electronic speed controllers (ESCs), and battery to ensure both fans operate in unison and provide the desired thrust. A typical installation might require parallel wiring of the ESCs to a single battery connection, allowing both fans to draw power simultaneously.
Employing a dual-fan arrangement offers several advantages, including increased thrust, improved scale appearance for model aircraft, and enhanced flight performance compared to single-fan setups. Historically, such configurations were employed to mimic full-scale jet aircraft designs more accurately, demanding precise electrical wiring for reliable operation and optimal power distribution. Proper assembly ensures a more powerful and balanced RC aircraft.
