PCR4S Receiver

PCR4S is a 4 channel receiver for up to 3 servos plus the on board brushed motor
ESC.  For brushless motors, there is an output on the board to interface with a
brushless ESC.  The LZS6, 0.6 gram micro-servos from Nick Leichty work perfectly
with the PCR4S receiver.  The dimensions are 10.5mm by 22.5mm and the weight is
0.5 gram, including the antenna.

Features:

Will work with the Plantraco 900MHz HF900 and Monolith transmitters.

Incorporate a 2A brushed motor speed controller.

Work on a single LiPo power.

Will sync up to your transmitter and not to somebody else’s transmitter further away
from you, regardless of the channel, as long as your transmitter’s channel is clear to
begin with.  This feature eliminates the original annoying channel manipulation
problem, when multiple transmitters are present.

A single 82mm antenna provides an adequate range of about 300 feet.

Low battery detection.  On low battery detection the motor will cut off.  You can
reactivate the motor for a short time, after moving the throttle stick to off position first.

Loss Of Signal (LOS) detection.  If the transmitter’s signal is lost, the motor will cut off
and the LED will go on and stay on for the duration of the LOS condition.  The
rudder/aileron will deflect slightly to avoid model run off.  If the transmitter signal gets
better, the controls will be reactivated, including the motor control.

After power on, the receiver will sync to your transmitter and the LED will count the
channel number.  For the USA channels the LED will indicate 1 to 6 counts and for the
European channels, 7 to 9.  After that the LED goes off and stays off, unless there is a
range problem or LOS in which case the LED gets activated.

The receivers don’t have connectors or plugs.  All connections to the battery, motor,
actuators and/or servos have to be soldered in using a low-watt soldering iron.  
Experience with micro-soldering is required.
