Read through the manual before you begin, so you will have an overall idea of what to do.
How to read the instruction manual:
Check all parts. If you find any defective or missing parts, contact your local dealer or our Kyosho Distributor.
This instruction manual uses seve-
ral symbols. Please note them
during the entire assembly.
Tighten the set screw into this
groove.
Key Number, Part Name, True-to-scale
Diagram, Quantity Used
Tail Rotor Assembly
Note the direction for .
Tighten both 2.6x10mm cap
screws ensuring the tail rotor
blades still have a little play
in the grips.
All parts except screws are identified by
key numbers. For purchasing spare parts,
find the key no. of the part needed in the
spare part list and refer to the left column
to look up the corresponding order no.
Symbols used throughout the instruction manual, comprise:
Part bags used.
Assemble left and right sides
the same way.
Drill holes with the specified
diameter (here: 2mm).
Cut off shaded portion.
Cut off excess.
Assemble in the specified
order.
Assemble as many times as
specified (here: twice).
True-to-scale diagram.
Pay close attention here!
Inside the kit, you will find assemblies, i.e. sections that are pre-assembled
and hence consist of more than one part. To make sure these assemblies
are safely assembled, check among others their screws for looseness. Only
then, build in the assemblies.

Ni-Cd BATTERY CHARGING
This kit contains screws and hardware in different metric sizes and shapes. Before using them, check the screws on the true-to-scale diagrams
on the left side in each assembly step. Some screws are extras.
Self-tapping (TP) screws cut threads into the parts when being tightened.
Excessive force may permanently damage parts when tightening TP screws.
It is recommended to stop tightening when the part is attached or when some
resistance is felt after the threaded portion enters the plastic.
This kit supplies altogether two instruction manuals: one for the frame
assembly, the other one for the body. In the latter one, you will also find
lists with spare and optional parts besides the explanations on how to finish
and mount the body.
Before assembling, (re)charge your Ni-Cd battery.
For this, please carefully read the instruction manuals or explana-tions
of both the Ni-Cd battery itself and charger unit!
