Thrust Bearing Direction
Main grips are factory preassembled; in case of reassembling
make absolutely sure you use the correct “ID”(inner diameter)
ring at the correct position. Place the large ID towards the main
shaft and the small ID towards the blades during assembly.
Use medium threadlock on all
screws going into metal parts
Mount the mainrotorhead
using the upper hole
VERY IMPORTANT:
The feathering/spindle shaft
screws are not secured. You
have to clean the shaft from
the inside and the screws
with alcohol and secure them
tightly with threadlock!
Use some light oil on the
main shaft for a smooth
travelling swashplate and
clean it regularly.
Be careful not to
overtighten the two
clamping screws (7) in
the main rotor hub.
Do not overtighten the two
M4x30 socket head bolts (2)
as it may result in sluggish
bearings in the A-arm
Install the linkage for the
elevator servo at the
swashplate before you
mount the swashplate
guide.
The Jesusbolt (6) just
carries the torque.
Tighten it firm but do
not use to much force.
