A BEC-equipped ESC meant for airplane use often incorporates a low-voltage-cutoff (LVC) circuit which can sense the voltage drop caused when the battery has little charge left. It then cuts the power to the 'drive' motor in order to provide the 'steering' servo (s) with enough power to be able to bring the model safely back to the operator.
A Plug-N-Play (PNP) electric RC airplane has the motor, ESC and servos installed but is missing the transmitter, receiver, and motor battery pack (& charger). In other words, the airplane comes 99% assembled just like an RTF one does, but you need to supply your own transmitter, receiver, and battery pack.
Many notable individuals in the 1960s through the 1990s and beyond created the landscape of modern RC modeling. These included many starting their own companies. The families of many of these individuals lost interest in continuing these businesses. The incoming supply of ARF planes from overseas made it hard to sell kits requiring assembly.
ESCs designed for radio-control airplanes usually contain a few safety features. If the power coming from the battery is insufficient to continue running the electric motor, the ESC will reduce or cut off power to the motor while allowing continued use of ailerons , rudder and elevator function.
The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. [1] It is a commutated series-wound motor where the stator 's field coils are connected in series with the rotor windings through a commutator .
The motor ran on a test dynamometer for 1,000 hours. The iron bird is a Caravan forward fuselage used as a test bed, with the usual PT6 turboprop engine replaced by an electric motor, inverter and a liquid-cooling system, including radiators, driving a Cessna 206 propeller. The production motor will produce 280 kW (380 hp) at 1,900 rpm, down ...
