Trimming Adjustments and Control Tests

Installing the battery
To install the Li-PO battery into the
fuselage insert the charged battery
into the bottom of the helicopter
base.
Checklist
Each time before you start flying your Merlin Flight Product, please carry out the following checks and tests.
•
Make sure the Swash plate has free movement
•
All screws, bolts, etc. are tight
•
Radio equipment is securely fastened inside fuselage
• Batteries are fully charged.
•
No wires interfere with servo motors
•
Blades are securely fastened
Control Test
•
Be certain that the throttle stick is in the "off" position. - 000
•
Switch on the transmitter, make sure the aerial is upright and check to make sure the Power indicator is full. If the indicator is empty and
flashing then the transmitter batteries are low on power and must be replaced before flying.
•
Plug in the helicopter battery and wait for the receiver power light to stop flashing to confirm the unit has calibrated.
•
Place your model on the ground and walk away whilst operating the swash plate controls.
• Check that the servos operate without interference up to a distance of 30 metres.
•
Gently move the throttle stick forwards to check the main blades rotate.
Trimming Check
1. Switch on your transmitter and make sure the throttle stick is fully pulled back. - 000
2.
2. Make sure the battery is plugged in. Leave the helicopter until you see the power light stop flashing and remain constant to confirm
the unit has calibrated.
3. If while flying, you notice the model drifts in any direction without you operating the controls, the model
can be trimmed using the trim tabs on the transmitter.
4. The trim tabs offset the centre position of the control stick to regain the models natural equilibrium.
5. Each Trim tab moves the centre position in the direction indicated on the tab, this is always from the
perspective of the helicopter cabin facing away from the operator.
6. If the model is drifting left, add a step of right trim. If the model is drifting forwards, add a step of back
trim. These both work for the opposite directions.
7. The throttle trim will generally not be needed as the model will not configure on start up if the throttle is
not set at zero. The only other trim is the rudder trim. If the model spins on its centre axis then the
rudder trim can be adjusted to compensate. Left trim is used if the canopy is spinning clockwise and
At all times the trim positions are shown on the LCD screen. The Indicator will move up and down the trim line
to show how much trim is currently being used. Once adjusted the trim will remain saved in those positions for
use next time. The transmitter will beep once when the trim is at the centre position for easy identification.
Advanced flight Characteristics Button
There are two flight modes for the Tracer 60 to help you get the most out the performance. Primary mode gives a basic speed and range of
movement from the controls and is the most stable of the two. The advanced mode gives a higher level of speed and movement from the controls
to give you a more hands on feel.
• The flight characteristics can be adjusted at any time while the transmitter is
turned on by pressing down the Cyclic control stick button.
•
The transmitter will beep and the Primary/Advanced mode indicator change from
a half circle for Primary to a full circle for Advanced.
