E-flite Control Line Motor Timer - Manual

Multiple-Function Electronic Timer
EFLA172
The E-flite C/L Timer has been designed to deliver control of an R/C ESC for use in an electric control line model. The
timer has a very low weight of only 3.2 grams and is very compact in size. The timer is programmable and has a second
function for controlling other features on your model such as retractable landing gear. The main features of the C/L
Timer are listed below:
1. Programmable timer settings in 1 minute increments
2. Motor rpm is adjustable from off to full throttle
3. Motor cut-off alert in flight
4. Gradual motor rpm slow down prior to cut off
5. Optional control for items like retractable landing gear
6. quick and easy stopping control
Introduction of Use
The top of the timer has the start button and Motor RPM adjustment knob. The label is located on the bottom of the
timer.
You will note the label is on the bottom of the timer. On the left side there are two sets of pins. These pins are for the
ESC and second function. Please note the labeling of the ground wire, positive wire, and signal wire on the left side of
the timer. This labeling is correct when viewed from the bottom of the timer. The ESC port is on the top of the timer
and the Optional control is for retract servos, etc. This is the port that is on the bottom of the timer.
In the middle of the label we show the Motor RPM potentiometer. This potentiometer is located on the opposite side of
the timer. To increase motor RPM you turn the knob clockwise. To decrease motor RPM you turn the knob counter-
clockwise. Please note that if you turn the knob fully counter-clockwise the motor will not run.
On the right hand side of the label we show the Start button. This button is located on the top of the timer. This button
controls the duration of flight as well as the emergency stop ability of the timer.
Battery power required for timer operation must exceed 5 volts as a minimum voltage.
Istructions for Use
Plugging in the ESC and optional device
1. Plug the ESC into the timer ensuring to align the ground and signal wires. The ground wire is usually brown
or black. The signal wire is usually orange or white. If you plug the ESC in backwards, the unit will fail to
operate. You will want to plug the ESC onto the top of the timer.
2. Plug the retract servo into the timer ensuring to align the ground and signal wires. This will plug into the
lower set of pins on the timer, or under the ESC.
3. If using the optional device (designed for retract operation) you will find the retracts to raise 15 seconds after
the motor begins to run. The retracts will lower 18 seconds before the cut-off warning occurs.
