Step 3 – Tail Servo Installation
First of all, mount the holder frame (70 ‐ 00097) onto the
boom holders (70 ‐ 00098) using screw M3x8. Then mount the
tail servo of your choice into the tail frame using screws
M3x10, washers and nylon nuts as shown. Install the servo
horn and the supplied uniball. Then slide the tail rotor control
rod (70 ‐ 00103) into the four guides. Install the ball link (70 ‐ )
on both ends of the tail rotor control rod. Distribute the
guides evenly along the tail boom. Then install the tail
fennestron frame onto the tail boom. Lock it with the three
screws as shown, but do not use thread lock yet, as it has got
to be uninstalled again. Snap the servo control rod onto the
ball link.
Step 4 – Cyclic Servo Installation
Install the three cyclic servos onto the servo tray as shown.
Depending on your servos, you may have to use washers to
adjust the servo to the proper installation height. It is strongly
recommended to use metal servo horns and only metal
geared servos. The multi blade rotor head can feedback
forces that may lead to failure of plastic components.
After the servos are installed, you will have to adjust the
linkage rods length’s according to the schematics below. The
distances are uniball center to uniball center:
1=81mm 2=112mm 3=81mm
