ROBBE ARROW PLUS TRAINER EVOLUTION Operating Instructions Manual page 10

Flight preparations
Switch the transmitter on (Fig. 1). The battery status is displayed at the
top of the screen. Move the throttle stick and trim to the bottom position;
if you do not do this, the motors will not run. Open the battery compart-
ment cover on the underside of the fuselage, and insert the LiPo flight
battery into the frame on the helicopter, in the direction of the arrow.
Connect the LiPo flight battery (Figs. 2 to 4), taking care not to move
the throttle stick. This procedure must be carried out before every flight.
Note: the 2.4 GHz transmitter and receiver are supplied already bound
at the factory. It will only be necessary to bind the system again after a
repair, or if you exchange a component.
