EP helicopter radio, and dry batteries

This kit requires a radio for EP helicopters

with 4 servos, 1 electronic speed controller

and 1 gyro.

For more information about the radio, refer

to its explanations.

A single Ni-Cd battery powers operation

and receiver. Ni-Cd batteries listed right

are suitable for use in your helicopter.

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!
