Trim Flight - Horizon Hobby BLADE 150S 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.
Entering Trim Flight Mode
1. Lower the throttle stick to the lowest position.
2. Center all trims.
3. Power ON the transmitter.
4. Install the flight battery in the helicopter.
5. Connect the battery connector to the ESC.
6. Place the helicopter on a flat surface and leave it still
until the motor beeps twice and the blue ESC LED
glows solid, indicating initialization is complete.
7. Place the helicopter where you are going to take off.
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.
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.
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
EN
The trim flight is used to determine the optimal settings for
SAFE technology during flight.
®
The trim flight must be performed in calm conditions.
8. Move and hold
the left stick to
the bottom left
corner and the
right stick to the
top left corner as
shown.
9. Activate Panic Recovery until the swashplate rotates
around once.
10. Release the sticks and deactivate panic recovery.
11. The model is ready for the trim flight.
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.
necessary. If you are still experiencing problems after several
attempts please perform the calibration procedure and try
the trim flight procedure again.
