Calibration Procedure DXS (RTF)
If the Blade 230 S Smart is experiencing drift issues after
completing the trim flight procedure located at www.blade-
helis.com, perform the following calibration. The calibration
procedure may also be needed following crash repairs.
WARNING: Before beginning the calibration
procedure, disconnect the main motor and tail
motor leads to prevent accidental motor startup
during calibration.
To perform the calibration procedure:
1. Ensure the surface used for calibration is level.
2. Power on the transmitter and helicopter, allowing them
to initialize.
3. Turn Throttle Hold ON.
4. Ensure the main motor and tail motor leads
are disconnected. Set the flight mode switch to
Intermediate Mode (FM1).
5. Using a bubble level as shown below, level the helicopter
by placing the Blade 230 S Smart foam blade holder
under the tail fin. Use additional items, as necessary, to
build up under the tail fin until the tail boom is level.

6. Hold the left stick
to the bottom
right corner, the
right stick to the
upper left corner
and activate the
Panic Recovery
function until the LED on the receiver flashes once.
7. Release both sticks and deactivate the Panic Recovery
function.
8. The LED on the receiver will remain solid for 1-2
minutes while the calibration takes place. Do not move
the helicopter until the calibration is completed. If the
LED begins blinking rapidly, an error has occurred. Begin
the calibration procedure again, starting with step 1.
9. After the calibration is successfully completed, the receiver
LED will blink slowly (2 seconds on, 2 seconds off).
10. Power the helicopter off.
11. Reconnect the main motor and tail motor wires.
12. Perform the trim flight procedure.
13. During subsequent flights after the trim flight, the helicopter
should return to within 5 degrees of level consistently.
