Assembly Mechanics
The mechanics are almost entirely preassembled and split up into four sections: rotorhead, main frame, tail frame and tail tube.
Prior to the installation into the scale fuselage, the mechanics have to be entirely assembled, electronic components installed,
adjusted and tested. After installation into the fuselage most of the helicopter mechanic become inaccessible.
Step 1 – Rotorhead
Slide the rotorhead onto the main shaft. Use screw (70 ‐
00006) and nylon nut (70 ‐ 00007) to secure the rotorhead
onto the main shaft. Use two screws (70 ‐ 00008) to
additionally clamp up the rotor hub onto the shaft as shown.
Make sure the distance between the ball link and the L lever
is equally at 24mm. Finally snap on the ball links (70 ‐ 00025)
on the swashplate’s upper disc uni ‐ links (70 ‐ 00030).
Step 2 – Tail boom
First of all install the center bearings (70 ‐ 00100) with the
holders (02 ‐ 02006) into the tail boom (70 ‐ 00095). Distribute
the bearings evenly in the tail boom. It is recommended to
apply a bit of lubrificant onto the tubes inner surface,
elsewise the bearing is likely to get stuck before the correct
position is reached. Then install the center support ring
(600UH1 ‐ 007), the servo rod guides (70 ‐ 00040) and the servo
two tail servo holders (70 ‐ 00098). Install the tail torque tube
(70 ‐ 00096) into the tail tube.
Then insert the tail boom into the tail boom holders (70 ‐
00093, 70 ‐ 00094). Lock the tube in place with screw M3x8
(70 ‐ 00086) via the clamp up and additionally with screw
M3x6 (70 ‐ 00053) as shown. Install the carbon support beams
(70 ‐ 00104 ‐ 70 ‐ 00106) on the main frame and the tail boom
tail boom clamp (600UH1 ‐ 007).
