INSTALLATION OF SWASHPLATE SERVOS
The linkage ball must be positioned between
17-19 mm
out on the servo arm (F
igure 1
).
We recommend
metal servo horn
the 120° placement of the servos inside Goblin means the arms are difficult to access.
For this reason it is advisable to ensure alignment of the servo arms (and sub trim set) before installation
of the servos in the model. Proceed with installation following the instructions below.

ASSEMBLY OF THE BALL ON THE HORN.
The rods going from the servos to the swash plate must be as
vertical as possible. Not all servos are equal, so to better align
them you can choose to use the supplied spacer H0031.

Chapter 5, Installation Of Swashplate Servos
Some example configurations:
CHOICE OF THE MOTOR PULLEY
It is important to choose the right reduction ratio to maximize efficiency based on your required
flight performance.
It is recommended to use wiring and connectors appropriate for the currents generated in a
helicopter of this class.
If you are using a head speed calculator which requires a main gear and pinion tooth count, use
214
teeth for the main gear (this takes into account the two stage reduction) and the tooth count of your
pulley as the pinion count.
Below is a list of available reduction ratios
:
H0175-18-S - 18T Pinion = ratio 11.9:1 H0175-22-S - 22T Pinion = ratio 9.8:1
H0175-19-S - 19T Pinion = ratio 11.3:1 H0175-23-S - 23T Pinion = ratio 9.3:1
H0175-20-S - 20T Pinion = ratio 10.7:1 H0175-24-S - 24T Pinion = ratio 8.9:1
H0175-21-S - 21T Pinion = ratio 10.2:1 H0175-25-S - 25T Pinion = ratio 8.6:1
GOBLIN COMET CONFIGURATIONS
Sport and Acrobatic Flight
Speed Flight
The high RPM flight condition should only be used while away from the pilot ( at least 30 meters).
Speed passes should always be made longitudinally to the pilot and spectators and always at a safe distance.

MOTOR BELT TENSION
*Assemble the motor and pinion to its mounting plate.
*Fit the motor assembly into position.
*With the minimum centre distance it is easy to install the belt. First put the belt on the motor pinion.
*Then put the belt around the big pulley.
*Rotate the motor several times by hand.
*The belt must be tight. The motor plate will start to bend abit .... ( until 0.5mm is normal ).
*Lock all screws.
Note
Check for vertical alignment of
the motor pulley. To do this, turn
the motor several times and
check to you see if the belt is
aligned with the big pulley (one
way bearing pulley). If the belt is
riding too high, simply loosen
the motor pulley and drop it a
small amount, if it is riding too
low, loosen the motor pulley and
raise it a small amount.
