Trim Flight; Calibration Procedure Dxs (Rtf) - Horizon Fitness BLADE 230 S Smart Instruction Manual

Trim Flight

Perform this procedure if the model is not performing well or
has been recently rebuilt from a crash.
The trim flight procedure was performed during the factory
test flight and only needs to be performed if you notice the
model is not returning to level consistently or if the model
does not remain still during stationary pirouettes.
Performing the Trim Flight
1. Slowly increase the throttle to lift the model into a
stationary hover. Make corrections as necessary
to keep the model still. Evaluation does not begin
until the throttle stick is over 50% and the sticks are
centered. Making corrections will not affect the result
but a longer flight may be necessary.
2. Keep the model stationary in a hover for 120 seconds.
Sliding and slow movements are okay. The main goal
is to keep the rotor disk level.
3. Once you are satisfied with the trim flight, land the model.
Exiting Trim Flight Mode
1. After landing, lower the throttle stick to the lowest
position.
2. Activate Panic Recovery for 2 seconds, or until the
swashplate moves, indicating the servo positions and
attitude values have been recorded and trim flight
mode has been exited.

Calibration Procedure DXS (RTF)

If the Blade 230 S Smart is experiencing drift issues after completing the trim flight procedure located at www.bladehelis.
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.

The trim flight is used to determine the optimal settings for
SAFE technology during flight.

The trim flight must be performed in calm conditions.
Flight Test
After performing the trim flight, test-fly the model to evalu-
ate the leveling characteristics.
• The model should return to level flight consistently.
• During takeoff, the model should lift off with minimal
corrections.
• During a hover, the control stick should remain close to
center. Small corrections are acceptable.
If the model performs poorly or does not level properly after
the trim flight, retry the entire trim flight procedure. If the
problem persists, inspect the model for damaged compo-
nents, a bent shaft or anything that may result in increased
vibration. The trim flight may not record the correct values
due to excessive vibration, flying in wind or the model
not staying level. In these cases, shorter trim flights may
be necessary. If you are still experiencing problems after
several attempts please perform the calibration procedure
and try the trim flight procedure again.
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.
