Final Adjustments - Tail Rotor Setup

11. Final Preparations

Gyro Gain Adjustment

The gyro assists in holding the tail rotor, actually compensating for changes in wind direction or quick movements.

First check that the gyro is installed correctly by watching the rudder servo. While holding the rotor head move the rudder

stick to the right and observe the direction the servo arm moves. Now quickly rotate the nose to the left, the servo horn should

move in the same direction. If the rudder servo horn moves in the opposite direction reverse the gyro direction.

Generally the starting setting for the gyro gain is 60%, keep increasing the gain setting until the tail starts oscillating back and

forth, then reduce the setting slightly.

Problem: Tail rotor makes sudden uncontrolled rotations.

Action: The gyro direction is possibly set in the wrong direction.

Before Flying Your Helicopter

Before each ight, check that all bolts and screws are tight. Simply ying your helicopter, will loosen any screws which are not

threadlocked or secured with a lock nut.

First Flights

For the beginner pilot, a training pod is strongly recommended to assist in learning to hover the helicopter with substantially

reduced risk of crashing. These systems provide an on ground training capability to allow pilots to become familiar with the

helicopter before actually leaving the ground. (Optional Item) Part # CN2007A.

Radio

Always turn the transmitter on rst, then turn on your receiver. Before every ight, it is recommended that a range check is per-

formed. This is performed by walking away from your helicopter with the antenna fully collapsed to 30 paces and have some-

one verify that all control surfaces are operating. If at any time the inputs being provided changes (signaled by the person

assisting you), then there may possibly be a communication problem. If you do not make this distance, have an experienced

modeler check over your setup and do not y until doing so.

What separates airplane radio equipment from the helicopter version is in the control of the individual curves discussed earlier

and in the Revo-mixing*.

Take a moment to consider the helicopter hovering in front of you.

Problem: Not enough pitch in

Action: Increase pitch by
