The manufacturing process of the carbon parts
often leaves micro-burrs and sharp edges. We
recommend de-burring the edges to minimize
the risks of electrical wire cuts, etc. Very
important in red line zone.

To maximize space for the batteries, it
is advisable to shorten the motor shaft.
Follow the dimensions given in this

Note:
The HPS head should be assembled with one, 1mm shim (HC230) and one,
0.2mm shim (HC232) on each side. The blade grips must move freely, but
they should not move just under their own weight. If the blade grips are too
tight, you can remove the 0.2mm shim (HC232) from each side. After
approximately 10/20 flights, please check preload, you can add one or two
0.2mm shim (HC232) if preload has changed.

Chapter 7, Assembling The Modules

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.
Figure 3 illustrates this.
INSTALLATION OF SWASHPLATE SERVOS
The linkage ball must be positioned between 17-19 mm out on the servo arm (F igure 1 ), recommended servo arm SAB
p/n [HA050/HA051]. 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. Figure 2 shows a completed installation.

Note: For safety reasons we suggest to not exceed 2000rpm.
Some example configurations:
TRANSMISSION SETUP
It is important to choose the right reduction ratio to maximize efficiency based on your required
flight performance.
The Goblin has many possible reduction ratios at your disposal. It is possible to optimize any motor
and battery combination.
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

MOTOR BELT TENSION
*Assemble the motor and pinion to its mounting plate.
*Fit the motor assembly into position.
*Compress the springs by pushing the motor toward the main shaft.

Motor Assembly
Note:
Check for vertical alignment of
the motor pulley. To do this, simply
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 up the motor pulley
and drop it just a little bit, if it is
riding too low, loosen up the motor
pulley and raise it a bit.
