Rotor head Block

[HI3160C]

Washout Pins

2.6x30mm x 2

[HW3170A]

Damper Rubber x 2

[HI3181]

Step 1 Rotor Head Block

From parts bag 1: Press in the

Damper Rubbers and the Washout

Pins into the Head Block. Apply one

drop of medium CA glue after the

pins are fully seated. The two M3x4

set screws are for static tracking of

the blades. Install the two M3x4 set

screws and torque evenly to maintain

static tracking of the rotor blades.

on the offset plates.

4x8 Ball Bearing x 2

[CNBB0840] - 50

From parts bag 1: Insert one ball

bearing into each bearing cup and

insert into the offset plate. Apply

one small drop of medium CA glue

to the back side of the bearing cup to

secure to the offset plate. Insert one

ball bearing into each tie bar. Insert

one M3x6 button head screw

through the right side hole of the

offset plate into one tie bar. Make

two identical sub assemblies. Note

that the bearing cups face outwards

from the head block. Insert one

M3x15 button head screw through

the tie bar bearing, slide one steel

spacer and carefully apply

threadlock to the exposed threads

and insert into the right side of the

head block. Do not overtighten.

Repeat for the second sub assembly.

Once complete, insert one M3x7

Special ball into each offset plate to

complete the assembly.

For each flight mode setting, there will be different

Revo-mixing amounts. For forward flight the settings

will be lower than hovering due to the aerodynamic

forces effecting the helicopter. Here is a starting point

for revo values:

Tail Rotor Setup

Problem: Not enough

pitch in tail rotor to

match torque setting of

engine.

Action: Increase pitch

by shortening the

rudder pushrod.

Nose rotates

left at hover.

Pilot

Nose rotates

right at hover.

Problem: Too much

pitch in tail rotor to

match torque setting of

engine.

Action: Decrease pitch

by lengthening the

rudder pushrod.

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.

Once the tail rudder pushrod is adjusted

correctly so the tail does not rotate ( don't consider

wind now ) the revolution mixing can be adjusted.

*Revolution Mixing

The revolution mixing function allows the helicopter

to climb or descend without the tail rotating. These

setting are set when using regular piezo rate gyros, if

using a Heading Hold gyro remove all tail mixing.

There is a high & low setting on the helicopter radio.

The values shown will vary depending on engine,

blade pitch and fuel but provide a starting point for

the beginner.

These values correspond to the total travel for the tail

rotor pitch. To adjust the high setting, hold the

helicopter at hover and increase the throttle so the

helicopter climbs steadily. Notice the direction the

nose rotates:

High Stick Setting: 40

Low Stick Setting: 20

Normal Flight

Mode

left increase revo value to

increase tail pitch.

right decrease revo value to

decrease tail pitch.

Nose rotates

High

Low

To adjust the low setting, start from a high hover and

decrease the throttle to descend, notice which direc-

tion the helicopter rotates.

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.

Solution: The gyro direction is possibly set in the

wrong direction.
