Connecting the SPMLTT1000
The Spektrum SPMFCF400 fl ight controller can be used directly with the
SPMLTT1000 sensor. When the fl ight controller is paired with the SPM4649T
reciever, the fl ight controller can send the lap timing information to the receiver
with the standard 3-wire receiver connection without any additional wiring.
Install the sensor from the top and solder the pins on the bottom of the fl ight
controller. The sensor should face out the left side of the quadcopter when
mounted to the fl ight controller.

Tip: The SPMFCF400 paired with the SPMLTT1000 uses the Lap Counter telemetry
function, delivering the same performance and features as X-Bus based systems. This
combination is the lightest, simplest solution to add Spektrum lap timing on a quadcopter.
Installing the SPMLTT2500 on a Surface Vehicle
For surface applications, the
sensor must be mounted where it
can have a visible line of sight to
the Timing Gate in a window or on
top of the vehicle. Select a vertical
or Horizontal gate confi guration,
and install the sensor to suit. The
sensor should point left or right for
a vertical Timing Gate, and straight
up for a Horizontal Timing Gate.
