SN-L+ USER MANUAL

② The vibration is large, and most of the vibration points fall outside the warning line, which easily leads to the FC
can’t calculate the correct attitude
 CALIBRATE LEVEL <SENSOR>-<CALI LEVEL>
① Ensure that the aircraft is level and static during horizontal calibration.
② Horizontal calibration is required after changing the mounting direction.
③ If you have not calibrated for a long time or the temperature difference has changed too much, you need to
recalibrate.
 SENSITIVITY ADJUSTMENT
① <BASE FUNCTION>-<AIL BASE GAIN> -<ELE BASE GAIN> -<RUD BASE GAIN> : The larger the value, the faster the reaction speed
and the excessive jitter.
② < BASE FUNCTION >-<FEED FORWARD GAIN> : The larger the value, the faster the response joystick will be, and the jitter
will be exceeded.
③ Adjustment Steps:
Step1：set <FEED FORWARD GAIN> , normally reduce feed forward gain to 45
Step2：set the < AIL BASE GAIN > -< ELE BASE GAIN > -< RUD BASE GAIN >. You can fly by default, then increase or decrease the
sensitivity according to the state of flight.
④ PID speed Factor
PRINCIPLE: the faster the speed, the smaller the rudder surface sensitivity should be. The greater the value, the greater the speed
involved in PID control.
EXAMPLE: when speed of the aircraft is very fast, the aircraft begins to shake; then you can increase <ADVACE FUNC>-<STAB
GAIN>-<SPEED PID FACTOR> value.
⑤ Altitude hold gain < ADVANCE FUNC >-< STAB GAIN>-<ALT HOLD GAIN >
IN RTH，ALT-HOLD, WAY-POINT mode, if aircraft action like this in the pitch direction:
please decrease alt-hold gain.
8. FLIGHT & CONTROL
 AUTO TAKEOFF：
① AltHold mode：Push the throttle to enough power and the aircraft will automatically climb to a height of 20m.
② RTH mode:
Way1: push throttle channel away from the zero position, give plain a speed until motor start.
Way2: push throttle channel away from the zero position, shake the aircraft, until motor start. Aircraft will auto climb at 30m.
