Building Instructions for the Predator series eCCPM helicopter kits.
Introduction
Congratulations on your purchase of Century Helicopter Product's newest RC helicopter model. The Predator
eCCPM is the most anticipated and long awaited Century model helicopter. The attention is well deserved as
the Predator will be unmatched in affordability, quality and performance. Compared to other 60 class models,
pilots will be elated to find the Predator is built to please. This kit will exceed your expectations for precision
control at an affordable price.
In order to take advantage of the Predator’s performance capabilities we recommend using a high quality
computer radio system with 120 degree and/or 140 degree eCCPM mixing. The radio system should have at
least 8 channels to use modern heading lock gyros and throttle governors. The radio should also have a
minimum of 5 programmable points on both throttle and pitch curves. Servos used should be quality coreless,
ball bearing and having a minimum torque rating of 70 oz/in. The tail rotor servo should have a servo speed
of 0.11sec/60 degrees or better.
Warning
This radio controlled model is not a toy! It is a precision machine requiring proper assembly and setup to
avoid accidents. It is the responsibility of the owner to operate this product in a safe manner as it can inflict
serious injury otherwise. It is recommended that if you are in doubt of your abilities, seek assistance from
experienced radio control modelers and associations. As manufacturer, we assume no liability for the use of
this product.
Pre-assembly Information
Upon opening the kit, all the major component parts are bagged by relationship to the different sections of the
helicopter. Some components of the Predator have been factory assembled. The instruction manual details the
assembly of all components, including factory assemblies, should servicing be required at a future time. Pre
assembled components, parts, screws, and nuts required for each step are packaged in the same bag.
At steps that require attaching steel hardware to plastic parts, the plastic part should be prepared ahead of
time by forming the threads with an available fastener of the same size. When the parts are ready for assem-
bly, a small amount of Slow CA should be applied very carefully to the formed plastic threads as the fastener
is installed. We do not warranty bearings that are frozen from glue.
Metal fasteners into metal parts should use Loctite 260 - Green.
Metal fasteners (set screws) should use Loctite 242 - Removeable.
Metal parts to bearings should use Loctite 262 - Permanent (requires heat to remove).
Tail gears and the autorotation unit require lubrication with a good quality thick bearing grease.
Be careful when opening each bag as not to lose any hardware. Care has been taken in filling and packing of
each bag however mistakes do happen, if there is a parts shortage or missing hardware please contact us at:
