LET Quick Start Guide
7.4 Accelerometer Calibration
The flight control system can do the Accelerometer Calibration automatically when the aircraft
makes the code binding. You can also use the following methods to calibrate (The motor must
be locked and right red LED go out).
(1)
Put aircraft to the horizontal position and keep static.
(2)
MODE 1:
Push the throttle stick to the highest point,
and move Elevator/Rudder stick to the bottom right
corner, enter into calibration mode.
MODE 2:
Push the Throttle/Rudder stick to the highest
point and right side, move the Elevator stick to the
bottom, enter into the Calibration Mode.
(3)
Right red LED indicator blinks once and lights off, means finished calibration.
Please re-calibrate Gyro and Accelerometer if the aircraft no gyro response or status is not stable.
7.5 GPS indicator lights
IMPORTANT: For SAFE flight in GPS flight mode:
The left red LED light should at least "double" blink, (two blinks at a time).
It is highly recommended that you wait for triple blink" 8 statelites before starting the flight.
NEVER attempt to AUTO-START with less than "triple blinks"
7.6 Motor Unlock / Lock
Motor Unlock
After binding the DEVO F7/DEVO 7 to the Runner 250, Check that all trims are neutral, the throttle stick is ALL the way Down
with the display indicating 0% throttle. Check that ALL switches are in the UP position. Gently push the throttle stick down and
move the rudder (YAW) stick to the left side. (on mode 2
radios throttle and rudder is the same stick). You will see
the right red LED light turn on, indicating that motors are
unlocked. Be very careful at this point, as pushing the
thottle up will start the motors.
You can test by pushing the stick up a little, the motors
should start.
Motor Lock
Lock the motors by moving the throttle stick all the way down and the rudder (YAW) stick all the way to the right. The right red
LED light will go out when the motors are disarmed.
TEST:
Push the throttle stick up a little, the motors
will not start when locked.
NOTICE:
The motors are LOCKED by default after
successful binding.
