Motor Mixer Checking - Zerotech YS-S4 User Manual

YS-S4 Multi-rotor Autopilot User Manual V1.4
After the CSC operation, push the THR stick slightly up. The motors should begin to turn. You need to apply more
throttle to take off normally.
7.3 Motor Mixer Checking
Before take‐off, you still need to check your motor mix control.
First let's take the quadcopter + type as an example to simply describe how to check motor mix control (Please
refer to the illustration for other aircraft configurations). You need to arm the motors and check what happens
when you advance the throttle stick, if the four motors rotate at the same speed this means the motor balance is
good.
1. To check the aileron channel, slightly push the aileron stick to the left, motor M4 should rotate immediately
(see 1 on the illustration below), the other three motors should keep still. Push the aileron stick to the right
slightly, motor M2 should rotate immediately (see 2 on the illustration below), the other three motors should
keep still.
2. Check the elevator channel. According to the aircraft symmetry it should be similar to checking the aileron
channel. Push the elevator stick up slightly, motor M3 should start to rotate (see 3 on the illustration below) now
slightly pull the elevator stick down and motor M1 should start to rotate immediately (see 4 on the illustration
below).
