SAFETY PRECAUTIONS

This radio control model is not a toy.

●This is a kind of machine including a rotor which rotates with high speed and has a possibility to be dangerous. You are responsible for this model's assembly, safe operation (place to fly, frequency) check and adjustment of the model.

●Assemble this kit only in places out of children's reach! ●Take enough safety precaution before and after operation.

After every flight, inspect screws and nuts for looseness, and parts for wear. Any damaged parts should be immediately replaced, repaired or adjusted for safe operation.

●Use only Kyosho genuine parts for replacement.

Failing to do so will result in accidents or malfunction of the model. Kyosho do not take responsibilities for the accidents and crashes if using the parts which are not Kyosho genuine ones.

●Always keep this instruction manual ready at hand for quick reference, even after completing the assembly.

SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE.

BEFORE YOU BEGIN (2)

5

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.

6

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.

Overtightened.

The threads are stripped.

ABOUT THE "PERSONAL FREQUENCY MONITOR"

するとブザー音とLED

Before operating your helicopter, plug the crystal of your frequency into the Personal FrequencyMonitor. As soon as you switch it on, you'll know for sure through an interfe-- rence signal and LED lamps whether somebody else is on your frequencyor not!
