INDEX
The Goblin is a high performance radio controlled helicopter.
The design is original, moving away from traditional schemes, searching rationality for simplicity.
Our goal was to create a simple, high performance helicopter, with a minimum of mechanical components,
and simple maintenance.
Please read this user manual carefully, it contains instructions for the correct assembly of the model.
Please refer to the web site www.goblin-helicopter.com for updates and other important information.
Thank you for your purchase, and have a great time with your Goblin!

NOTES FOR ASSEMBLY
P
lease refer to this manual for assembly instructions for this model.
Follow the order of assembly indicated. The instructions are divided into chapters, which are structured in a way that
each step is based on the work done in the previous step. Changing the order of assembly may result in additional or
unnecessary steps.
Use thread lockers and retaining compounds as indicated. In general, each bolt or screw that engages with a metal part
requires thread lock.

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.

Note 1:
When you tighten the collar ( H0127-S ) on
the main shaft, ensure there is no axial play. Push
down the main shaft while pulling up the locking
collar. Tighten the screw M4x22 at this time.
Note 2:
The pinion and gear are designed to have zero
backlash. This leads to initial “rough” rotation.
After some run in flights ( 3-5 flights ) it will begin
to rotate freely, ensuring perfect contact and
the ability to transmit maximum power.
It is advisable to lubricate these two elements
with a lubricant (eg Silicone or Tri-Flow Synthetic
grease).

Note:
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.

each side. In this way, the preload is medium.
(see page 33 for some info about.)
After approximately 10/20 flights, please check the
preload, you can add one or two 0.2mm shims
( HC232 ) if the preload has changed.
(Initial length for the rods from the swash plate
to the Blade Grip.)
