eCCPM Frame

for the Quick of Japan EP-8

EP-8 SE

(Special Edition)

Introduction

Thank you for purchasing the new Rotorworkz carbon fiber eCCPM frame for the Quick of Japan EP-8 RC helicopter. We are sure you will be quite pleased with the performance results achieved after installing this frame modification. As well, you will begin to rely on the durability this frame possesses, further enhancing your flight enjoyment.

Before you begin assembling your frame kit, there are a few considerations you must make. First, there are several positions in which to mount each of your radio and power components, and proper layout will ensure success. Always try to keep your power components as far away from the radio components as possible. Be sure to use a high quality antenna, mounted well away from the carbon fiber airframe.

You must also consider the center of gravity once the completed helicopter is ready to fly. Component placement can alter the center of gravity, negatively affecting flight performance and stability.

Once you have a plan in mind, you can begin gathering the required tools and supplies. Below is a list of everything necessary to complete your helicopter:
