In
small helicopters, the ESC will be build into
the helicopter receiver. In larger helicopters
you are more likely to find the ESC separate
from the receiver. Connecting-up the speed
controller is fairly easy and straightforward.
Make sure that you use gold plated connectors
for connecting the ESC to the brush/brushless
motor and Dean plugs
for connecting the ESC to the power pack. The
brushless ESC have three cables that will be
connected to the brushless motor. The ESC for
brushed motors will only have two cables that
will be connected to the brushed motor.
Then
you have two cables (black and red) that will be
connected to your power pack(s). For the ESC to
get a signal from the receiver you need to pug
the JR connector into the receiver throttle
channel.
When
connecting the motor to the speed controller,
you must make sure that the direction of the
motor is correct. You can do a test after the
motor is installed and the cables connected to
the ESC. Take the main rotor blades of before
you do the test. If the direction on the
brushless motor is incorrect, only swap two of
the three cables. If the direction on a brushed
motor is incorrect, swap the two motor cables. |
