Your Wattage Wild Cat 400 EP ARF is powered by the Wattage Super Cobalt 400 Direct Drive motor. This motor is
a high-quality alternative to lower powered, closed end-bell motors, and more expensive specialty motors. The Super
Cobalt 400 Direct Drive motor features a 3.2mm (1/8") shaft and a bolt pattern that can match either 05 or 400 size
mounting dimensions. And at 3.7 ounces, this motor is light for its enormous power potential.

Continuous amps should not exceed more than 30 amps, so if you use propellers larger
than 7 x 4, you will need to reduce voltage accordingly.
The covering material used on the Wattage Wild Cat 400 EP ARF is real iron-on, heat-shrink covering material, not
cheap "shelf paper." Because of this, it is possible with heat and humidity changes that the covering on your airplane
may wrinkle or sag. This trait is inherent in all types of heat-shrink material. To remove any wrinkles that might be
visible you will need to purchase, or borrow from a fellow modeler, a heat iron. If you need to purchase one, the
Global Heat Sealing Iron # 360900
is recommended.
Follow this simple procedure to remove the wrinkles:
❑
Plug in and turn on the sealing iron to the medium-high temperature setting. Allow the iron to heat up for approximately
5 - 7 minutes.
❑
After the iron has reached temperature, lightly apply the iron to the wrinkled section of the covering. Move the iron
slowly over the wrinkled section until the covering tightens and the wrinkles disappear. You will notice that the color of the
covering will darken when it is heated. When the covering cools back down, it will return to its normal color.
☞
If the color layer smears from any of the seams the temperature of the iron is too hot. Turn the temperature dial down
and wait about 5 minutes for the iron to adjust to the lower temperature. You can remove any excess color streaks using
a paper towel soaked with a small quantity of acetone.

✦
We do not suggest storing your airplane in an extremely hot environment (like the back of your car in
direct sunlight) for any length of time. The extreme heat could distort the molded plastic fuselage and/or cause the
covering material to wrinkle and possibly damage the fragile components of the radio system, ESC or batteries.
