If at any time during the test the controls do not respond properly, double-check the servo reversing switches
located under the door on the bottom left front of the transmitter. Dip switches 5 (THR channel reversing), 6 (AIL
channel reversing), 7 (ELE channel reversing) and 8 (RUD channel reversing) should be positioned as shown to
ensure proper control response.
Note: All other dip switches should also be positioned as shown to ensure proper operation. DO NOT
attempt to fly your Blade™ CX2 with any of the dip switches set in positions that are not shown. The
remaining dip switches may be used for future expansion.
If the controls still do not respond properly after ensuring that the servo reversing dip switch positions are correct,
you may also check the servo connections on the receiver side of the 4-in-1 unit. These should be positioned as
follows (when viewing the helicopter from behind):
AIL Channel – Forward aileron servo
ELE Channel – Rear elevator servo
Once you have confirmed that the servo connection locations are correct, all controls should be functioning
properly. If you do encounter any problems with your Blade CX2 responding properly to the transmitter, do not fly.

If you have confirmed proper control operation of your Blade CX2, unplug the flight battery from the
4-in-1 unit and reconnect the main motor plugs to the 4-in-1 unit, taking care to keep the proper
polarity and location of each as they were before the test. Use the label on the 4-in-1 unit for
reference of the proper polarity and locations. Note that the red wire leads are positive (+) and the
black wire leads are negative (−).
