ABOUT HEAD
The HPS head allows for a very broad range of dampening setups.
The dampers are composed of 3 O-ring ( that defines the rigidity ) and a technopolymer damper
(that defines the maximum possible movement of the spindle).
Using different Oring and dampers you can get different responses of the model.
Oring
80 Shore: Soft for smooth response
90 Shore: Firm for direct and precise response
A = Max movement of the spindle, feeling more elastic.
B = Medium.
C = Min movement of the spindle, feeling more direct.
In the kit, there is the damper H1046-B with 90 Shore O-ring
[other Setting >>p/n H1135-S, HC530-S].
ABOUT THE TAIL
The standard SETUP is optimized for 3d flight, headspeed 2200 rpm. If you prefer flying at low
speed (< 2000 rpm), for best results we recommend changing the tail pulley to increase tail rotor
rpm. In this way, you will have extremely precise tail control even at low RPM.
This pulley is available in the upgrade list [H1098-26-S]
If you want to fly under 1800 rpm, we suggest to use bigger 115 mm tail blades.
OPERATIONS BEFORE FLIGHT
*Set up the remote control and the flybarless system with utmost care.
*It is advisable to test the correct settings of the remote and flybarless system without main blades or
tail blades fitted.
*Check that all wiring is isolated from the carbon/aluminum parts. It is good practice to protect
them at the points where they are at most risk.
*Be sure of the gear ratio, verifying carefully the motor pulley in use. The forces acting on the
mechanics increase enormously with increasing of rpm. Although the Goblin can fly at high rpm,
for safety reasons we suggest to not exceed
2200rpm
.
*Fit the main blades and tail blades. (
Figure.1
and
Figure.2
)
*Please make sure the main blades are tight on the blade grips, you should be able to violently
jerk the head in both directions and the blades should not fold. Failure to tighten the blades
properly can result in a boom strike. To fold the blades for storage, it is advisable to loosen them.
*Check the collective and cyclic pitch. For 3D flight, set about +/-13°.
*It is important to check the correct tracking of the main blades.
On the Goblin, in order to correct the tracking, adjust the main link rod. This is provided with a
right/left thread system that allows continuous fine adjustments of the length of the control rod;
for this adjustment it is not necessary to detach the ball link.
*Confirm the canopy is secure prior to each flight.
* Make sure that the battery locking pin is back in its resting position, blocking in correct way the battery tray.
*Perform the first flight at a low headspeed, 1800 RPM.
After this first flight, do a general check of the helicopter. Verify that all screws are correctly tightened.
