1. Pull the tail belt pulley off of the one-way bearing
sleave. Remove ten 2x4mm fl athead screws from
the tail drive pulley one at a time and re-install them
using medium thread-locking compound.
2. Remove fi ve 3x6mm fl athead screws one at a time
from the main gear and re-install them using medium
thread-locking compound. Re-install the tail belt pulley
on the one-way bearing sleave, ensuring the hole in the
pulley aligns with the holes in the sleave.
3. Slide the main gear assembly through the side of the
frame.
4. Place the tail belt around the upper gear as shown.
5. Slide the rotor head assembly down through both
bearing blocks and the main gear assembly.
6. Secure the main gear to the main shaft using a
4x20mm bolt and lock nut.
Do not use thread-
locking compound on the bolt and lock nut.
7. Attach the anti-rotation bracket to the back of the
upper bearing block using two
M3x6mm button head screws
and medium thread-locking
compound. Ensure the anti-
rotation pin is facing the rear
of the frame and is inserted in
the bracket before securing the
bracket to the bearing block.
8. Rotate the rotor head to ensure
it rotates freely.
1. Attach your chosen motor to the motor
mount using four 3x8mm screws and
medium thread-locking compound. The
motor leads should face toward the front
of the aircraft when installed.
2. Attach the pinion gear to the motor shaft
using two 4x4mm setscrews and
high
strength thread-locking compound.
3. Prepare the motor leads for connecting
to the speed control. If using the
recommended speed control, solder the
large bullet connectors to the motor leads.
4. Attach the motor mount assembly
between the frame sides using
M3x10mm screws, machined frame
doublers and thread-locking compound.
