When securing the pinion gear, be sure
that the 3 x 3 mm set screw engages the
flat spot of the motor shaft.
Motor Installation
When installing the motor, it will be
necessary to pass the socket head
bolt through the hole on the interme-
diate gear. Next, adjust the gear back-
lash and secure the bolts completely
using Threadlock.
Adjust the gear backlash
before securing the 3 x 3 mm
socket head screw.
Gear Backlash Adjustment:
For smooth
operation and performance, it is necessary to
adjust the gear backlash properly. Excess gear
backlash can cause premature gear wear and
damage. Insufficient gear backlash can cause
vibration, as well as overheating of the motor
and speed controller. Adjust the gear backlash
by placing one piece of paper between the
gears to set the distance. When the bolts are
secure, remove the paper and test the gear
backlash to insure that there is a slight amount
of free movement between the gears.
Important Note:
Once the
gear backlash has been adjust-
ed, loosen the pinion gear set
screw and raise the pinion
gear so that it no longer
engages the intermediate gear.
This procedure must be
observed to prevent accidental
blade start-up during initial
radio setup and adjustment.
