This manual has been written for Century’s 50 size Bell 47G II scale helicopter available in ARF
version and conversion kit. This is the detail construction of the Bell 47G II helicopter fuselage compo-
nents, landing gear, tailboom assembly which work in cooperation with the scale mechanics instruc-
tion manual. This manual should be reviewed before starting the assembly as there are steps in-
cluded that are different than in the generic scale mechanics manual. At steps that seem to be incor-
rect, simply refer back to this manual to find the correct components.
