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.

After tightening, check the
axial play of the main shaft. It
is possible to reduce any axial
play by adding shims.
IMPORTANT: Very carefully
check to make sure you can
turn the main shaft freely.
If you feel too much friction,
you have used too many
shims, you can remove a shim
until the shaft turns freely.

NOTE: We recommend assembling without shims for sport flying.
The HPS head should be assembled with one 1mm spacer H0225
on each side. After approximately 10/20 flights, please check
preload, you can add one or two shim HC228 if preload has
changed. For hard 3D, the best setup is add one extra shim
between the spacer H0225 and bearing. Important is that the
blade grips must move freely, but they should not move just
under their own weight. You can find HC228 in the Bag 11.

this, you must chose from one of the options shown here.
Figure 3 shows the installation of the servos at 120 degrees.
Note that the distance between the carbon fiber servo
mount and the center of the ball should be 18.5mm.
Figure 4 and figure 5 shows 8 different mounting options,
the distance “X” should be as close as possible to 18.5mm.

Note: Although the Goblin can fly at high RPM, for safety reasons we recommend not exceeding 2900 RPM.
Motor
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 moror and battery combination.
It is recommended to use wiring and connector 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 165 teeth for 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:
H0215-15-S-15T Pinion = ratio 11:1 H0215-20-S-20T Pinion = ratio 8.26:1
H0215-16-S-16T Pinion = ratio 10.33:1 H0215-21-S-21T Pinion = ratio 7.87:1
H0215-17-S-17T Pinion = ratio 9.72:1 H0215-22-S-22T Pinion = ratio 7.51:1
H0215-18-S-18T Pinion = ratio 9.18:1 H0215-23-S-23T Pinion = ratio 7.19:1
H0215-19-S-19T Pinion = ratio 8.7:1 H0215-24-S-24T Pinion = ratio 6.91:1
These are pulleys for motors with a 6 mm shaft. Each pulley includes an adapter for motors with a 5 mm shaft.

De-Burr The Side Frames
We recommend de-burring the edges of the carbon parts in areas where electrial wires run.
ESC Installation
The electronic speed control (ESC) is intalled in the front part of the helicopter.
If you have drilled the 4 holes (Fig 1) as suggested on page 5, you can easily fasten the ESC with cable ties as shown in figures 2 and 3.
Figure 4: You can see the wiring for connecting the ESC to the central unit.
Route the ESC throttle wire as shown, you can use cable ties to keep the wire in place.
Figure 5: You can install a BEC ( or 2S battery ) if required as shown.

We recommend the use of a one unit flybarless system, i.e. Mini vBar, Vortex, Microbeast, etc.
However, a two unit flybarless system can also be installed. For one unit systems, the unit is installed as shown in position 1 (Fig 1)
Two unit systems can be installed as follows: control unit in position 1 and sensor in position 2 or vice-versa. (Fig 1). See Fig 2, 3 & 4.
Position 3 and 4 can be used for a Spektrum sattelite. (Fig 1)

To maximize space for the batteries, it is advisable to shorten the motor shaft.
Follow the dimensions given in this drawing.
For the cut, you can use an electric tool like a “Dremel” with a cut-off disc.
Additionally, ensure the motor shaft has an appropriate 'flat' for one of the set screws.
