ABOUT HPS
The HPS head allows for a very broad range of dampening setups.
The dampers are composed of an O-ring and a technopolymer damper that defines
the maximum possible movement of the spindle.Using different dampers
we can get different responses of the model.
A = Soft for smooth response.
B = Medium.
C = Firm for direct and precise response.
In the kit, there is the damper for direct and precise response H0426-C.
(Other Setting >>p/n H0426-S )
If you like full rigid solution, you can use H0426-D-S.

MAINTENANCE

*On the Goblin, areas to look for wear include:
* Motor belt
* Tail belt
* Damper
* Main gear and pinion
The lifespan of these components varies according to the type of flying. On average it is recommended to replace
these special parts every 100 flights.
*The head tends to lose rigidity after a while. Check this condition every 20 flights. Preloading with precision shim washers,
it is possible to vary the rigidity of the head.
*Check all uniballs often.
*The most stressed bearings are definitely those of the tail shaft. Check them frequently.
All other parts are not particularly subject to wear.
*Periodically lubricate the tail slider and its linkages, as well as the swashplate and its linkages.
*Lubricate the main gear with silicone and Tri-Flow Synthetic grease, even though the gear is made of technopolymer,
a high mineral based filler, it still requires some lubrication.
*Check the screws that are highlighted in the following images frequently, make sure you remain tight ( fig.2 and fig.3).
*To ensure safety you should do a general inspection of the helicopter after each flight. You should check:
* The maintenance of proper belt tension.
* The proper isolation of wires from the carbon and aluminum parts.
* That all screws remain tight.
