Tail Blade
Maintenance
*The lifespan of these components varies according to the type of flying. On average it is recommended to check these parts
every
100
flights. In some instances, based on wear, these parts should be replaced every
200
flights.
*The most stressed bearings are definitely those on the tail shaft. Check them frequently. All other parts are not particularly
subject to wear.
*Periodically lubricate the tail slide movement and its linkages as well as the swash plate movement and its linkages.
*Lubricate the main gear with Dry-Fluid or Tri-Flow Synthetic grease, even though the gear is made of technopolymer,
a high mineral based filler, it still requires some lubrication.
*To ensure safety you should do a general inspection of the helicopter after each flight. You should check:
- Proper belt tension (motor belt and tail belt).
- Proper isolation of the wires from the carbon and aluminum parts.
- All screws remain tight.
After a crash, please inspect the carbon servo mounts H0308 to make sure they are not cracked or weakened. Failure to check and
detect a possible crack could result in a future crash if a carbon servo mount breaks in flight.
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 2600rpm.
*Check the correct tension of the tail belt through the belt tensioner.
*Fit the main blades and tail blades. (
Fig.1
and
Fig.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 as shown in
Fig.3
. 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.
*Perform the first flight at a low headspeed, 2200 RPM. After this first flight, do a general check of the helicopter.
Verify that all screws are correctly tightened.
