INTRODUCTION
Congratulations on your purchase of the JR Ergo helicopter kit. This kit has been both engineered and manufactured by JR with help from some
of Japan’s top R/C helicopter engineers (now employed by JR). As you may well know, the name JR has for years been synonymous with state-
of-the-art, high quality radio control systems known the world over for their exceptional reliability and engineering.
JR now brings this reputation and knowledge into the helicopter market with the development of the Ergo and the organization of the JR heli division. Years in the making, the Ergo’s superior quality and exceptional parts fit and finish create a new standard of quality that was previously unavailable.
Before you begin the assembly of your Ergo, we suggest that you first review the entire instruction manual to become familiar with the assembly sequences and parts layout.
WARNING
The radio controlled model helicopter contained in this kit is not a toy, but a sophisticated piece of equipment. This product is not recommended for use by children. Radio controlled models such as this are capable of causing both property damage and/or bodily harm to both the operator/assembler and/or spectator if not properly assembled and operated. Horizon Hobby Distributors assumes no liability for damage that could occur from the assembly and/or use/misuse of this product.
AMA INFORMATION
We strongly encourage all prospective and current R/C aircraft pilots to join the Academy of Model Aeronautics. The AMA is a non-profit organization which provides services to model aircraft pilots. As an AMA member you will receive a monthly magazine entitled Model Aviation, as well as a liability insurance plan to
cover against possible accident or injury. All AMA charter aircraft clubs require individuals to hold a current AMA sporting license prior to operation of their
models. For further information, you can contact the AMA at:

PRE-ASSEMBLY INFORMATION
When first opening your Ergo kit, you will notice that all of the parts are packaged and numbered to coordinate with the assembly step numbers of this instruction manual.
All small hardware (nuts, bolts, washers, etc.) for each step are separated and packaged separately within the main parts bags. When beginning a section, you will need to open only the bag with the corresponding number to the section you are going to start. It is suggested that you place all of the hardware in an open container (e.g., coffee can) during assembly so as not to lose any of the small parts. It may also be helpful to familiarize yourself with the various sizes of screws, bolts, nuts, etc., as illustrated in the appropriate assembly section before you begin assembly. At the end of each assembly, in most cases, there should be no parts remaining.
Great care has been taken in filling the bags with the correct quantity of parts and hardware for each section. However, occasionally mistakes do happen. In the event that you find a parts shortage or are in need of technical assistance, please contact your local JR heli division parts dealer, or contact the Horizon Service Center directly.
