Operation Manual

IN FLIGHT
3 blade rotor heads require a much lower cyclic gain on flybarless systems.We recommend that you set your gain at least
30% lower than the gain you normally use on your 2 blade rotor head helicopters.You can start increasing the gain after
you complete your first flight. Running too high of a gain can induce a violent oscillation that can potentially cause damage
to your helicopter in flight.
If the model is making strange noises, this can be usually attributed to incorrect belt tensions. Check the belts again and
tighten if necessary.
It's very important to check the model thoroughly after the first 2-3 flights. Check all bolts, screws, belts, ball links, etc.
SERIAL NUMBER
In Bag 19, you will find the serial number tag for your Helicopter.
Apply the tag as shown. Please remember to register your product. (See page 1)
Always in Bag 19, you can find also the KSE plate.

OPERATIONS BEFORE FLIGHT
*Set up the transmitter and the flybarless system with utmost care.
*It is advisable to test the correct settings of the transmitter and flybarless system without main blades and 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
at higher RPM. Although the Goblin can fly at very high RPMs, for safety reasons we suggest to not exceed 3400 RPM.
*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 during spool up.
To fold the blades for storage, it is advisable to loosen them.
*Check the collective and cyclic pitch. For 3D flight, set about +/- 12.5°.
*It is important to check the correct tracking of the main blades. (Fig 3).
*Perform the first flight at a low head speed, 2400/2500 RPM.
After this first flight, do a general check of the helicopter. Verify that all screws and bolts are correctly tightened.
