Step 33 Upper Side Frame Assembly
Install the upper main shaft bearing block with the bearing facing upwards onto the left upper side frame (notice the counter-
sunk hole) using two M3x8 socket cap screws. Install the clutch bell assembly with bearing blocks using four M3x8 socket
cap screws and four M3 flat washers. Install one M3x8 socket cap screw only into the forward most hole in the lower bearing
block and install the 26mm hex spacer in the front of the upper frames, secured using one M3x8 socket cap screw. Do not
use any threadlock on bearing blocks or frame spacers until the gear mesh is set.
CCPM (cyclic collective pitch mixing) requires that the three servos that drive the
swashplate be the same model and more importantly the same speed and torque
rating. Digital and analog servos will fly the Predator with ease as long as the
minimum torque rating selected is 70oz/in, rated at 4.8 volts.
Step 34 Elevator Servo
Look at the upper side frame, the remaining right side will have the
slots to install the elevator servo. Having previously installed the
rubber gromments and eyelets (see on the right), install the eleva-
tor servo with its output shaft to the rear from the inside (outside
has the countersunk hole above the main gear) of the side frame,
and secure using four M2.3x10 Phillips servo screws
and two servo mount tabs. Continue tightening the
screws until tight, then back off
1/4 turn.

Servo Grommets & Eyelets
Install the four rubber gromments
that are supplied with the servo
onto the servo mounts and insert
the brass eyelets so that the flat
washer side of the eyelet is in-
stalled against the side frame. For
the elevator servo the eyelets are
installed from the top of the servo.
