Important Note:
Once you finish assembly,
check the system can slide and move without friction.
If tail system is assembled correctly, it should move
smoothly and without play. In case of friction or play
recheck each single component and re-assembly as
required. If necessary adjust the position of the Bell
Crank Arm. A common mistake would be allowing
loctite to contaminate the bushing and plastic in step 2.
Note: Line up
the holes so
the set screw
seats correctly.
