the motor at C1 to “idle re.” and the

Also note the model settings
STEP THREE: Go to the “cont. sett.”
menu and assign channel 5 to switch
S3 to control attitude and rate mode.

Set stick mode to 2 and the timer for 5
minute flight. The timer is activated
with switch S1. In this menu you also
need to bind your RX to the new
model created.

to EAR to provide a connected
headset with voice telemetry data.
