7. BEC = (BATTERY ELIMINATOR CIRCUIT)
MULTIcont BL-15 speed controllers are equipped with a BEC
system: the receiver and servos are fed power from the flight
battery via the regulator; no separate receiver battery is required.
Never connect a separate receiver battery!
Please note that the MULTIcont BL-15 speed controller’s BEC
power supply can only deliver a limited current to the receiving
system in the model:
The actual current drawn by a servo varies according to its
performance, the frequency of commands and – in particular –
the freedom of movement of the control surface linkages (!). This
means that it is essential to measure the current drain of the
