not correct, just swap the two ESC signal wires.
Preflight inspection
➢ Feedback direction
*If the feedback direction is not correct, you can invert the channel in OSD.
*The feedback direction must be set first, then the RC control direction.
➢ RC control direction
*If the control direction is not correct, you can set the channel output reverse in the RC.
*After setting the feedback direction, the control direction can only be modified in the RC.
➢ FailSafe
When the RC that outputs PWM/PPM/IBUS/CRSF is failsafe, there are usually three
states that can be set.They are: cut (no output), pos hold (hold the output at the last
moment before failsafe), custom (the user sets the output when failsafe), of course, different
RC will be different.
Cut mode: the FC can automatic recognition as failsafe,and switch to RTH;
Pos hold: this mode is not recommended.
Custom mode: the user sets the output data of each channel when the RC is failsafe, to
ensure that the output of the mode channel(CH5/CH6) can make the FC switch to RTH
when the RC is failsafe. Therefore, RTH must be included in the three modes set in the OSD.
PWM/PPM/IBUS/CRSF: it is recommended to use cut mode or custom mode.
SBUS: the FC can automatic recognition as failsafe,and switch to RTH.
