Optional: If the motor off area is not desired in Attitude mode
then you can reduce the lower servo travel to -70%. Thus the
reduction has no effect on the rate mode, program the reduc-
tion through a switchable free mixers. In this mixer the reduc-
tion is active only in Attitude mode. (see display screenshot on
the left)
Oneshot
Oneshot is a quick communication protocol between receiver
and speed controller and should only be activated if the speed
controllers allow this function. It allows the speed controllers to
communicate much faster with receiver. So the motors react
faster to receiver controls. The motor output signal is now
shorter, about 125µs-250µs, instead of before PWM (1000µs –
2000µs).
Minpower%
The setting is principally used to prevent the motors shut down
in flight. Adjust so that the motors are running straight. Under no
circumstances unnecessarily high set, this would limit the con-
troller possibilities.
Logging
Value 1 is the general attitude control, rest as needed
logs the corresponding servo to SD card for later evaluation and
error analysis.
Settable values:
0 = No logging, Telemetry display of Euler and yaw angle
1 = roll and nick logging
We recommend always logging at least one function.
CALIBR. POSITION
With Calibr. Position the acceleration sensors can be calibrated
so that in attitude mode with stick and trim neutral, the copter
is precisely horizontally aligned. For this purpose, it is simply
placed on absolute level surface and set the value to Yes. After
a moment, it jumps back to No and the calibration is done. Do
not forget to store disabling the field!
Setup: Setup: Yes/No
Assignment of the gyros and their operating direction.
In the receiver's "Axis assign" menu, go to the "Setup" option
and set it to "Setup: Yes". Now assign the axes as follow:
+0
On the transmitter, briefly set the roll command fully to the right;
+0
the roll axis is highlighted. Roll the copter more than 45 degrees
+0
to the right the identified axis with the required prefix is dis-
played, the field is no longer highlighted and identification of this
axis is complete.
