not allow anything to obstruct the free circulation of air
5. ASSEMBLING OF THE POWER SET
”MERLIN -TUNING”
1.Screw the motor to the motor bulkhead ensure that
the motor is free to rotate. When deploying the motor
leads check that they cannot foul the rotating part of the
motor.
2.Slip the propeller driver and the hexagon driver nut on
the motor shaft.
3.Fit the blade holder on the propeller driver followed by
the plain washer, the shakeproof washer and the
hexagon nut. Tighten the nut firmly.
4.Attach the folding propeller blades to the blade holder
using the dowel pins supplied in the set. Fitting the
spinner prevents the pins shifting.
5.Fix the spinner to the blade holder using the retaining
screws.
6. INITIATION OF THE POWER SET “MERLIN -
TUNING”
1.Connect the three wires attached to the speed
controller to the three wires attached to the motor; the
order of connection is unimportant.
2.Locate the UNI connector attached to the speed
controller, and connect it to your receiver.
3.Switch the transmitter on, and check that the throttle
control is at the “OFF” position.
4.Connect the flight battery to the speed controller.
5.Check the direction of rotation of the motor: it should
spin clockwise when viewed from the tail, looking
forward. If this is not the case, disconnect the flight
battery and swap over any two of the three motor wires.
6.Set the motor brake on the speed controller to “ON”;
the procedure is described in the speed controller
instructions.
