To operate the motor, we suggest using a proportional electronic speed control (ESC) that features battery eliminator
circuitry (BEC) and auto-cutoff. BEC allows you to eliminate the receiver battery and uses the flight battery to control
both the motor and the radio system. Eliminating the receiver battery provides a great weight savings which effectively
increases performance. The auto-cutoff feature turns off the motor when the voltage in the battery drops too low to
operate the radio system safely. This guarantees safe operation throughout the entire flight. To obtain these features, we
suggest using the Wattage IC-380 ESC. You can also upgrade to the Wattage IC-14 ESC (part # 128484). This ESC is
smaller and lighter, and includes special tabs that hook directly to most speed 380 motors. This means there isn't any
soldering required and you won't experience current loss because of poor connectors. If you decide not to use a propor-
tional electronic speed control, an electronic switch like the Hitec Motor Controller SP-1003 (part # 759850) is an
economical way to turn the motor on and off. This switch does not offer any proportional speed, only off or full power.
The battery you choose should be a 6 cell (7.2Volt) to 8 cell (9.6Volt) 650Mah Nickel Cadmium (NiCd) battery pack or a
6 cell to 8 cell 650Mah Nickel Metal Hydride (NiMh) battery pack. The 8 cell battery pack will provide more power,
resulting in higher speeds and better climb-out, but weigh more than the 6 cell battery pack. The Nickel Metal Hydride
battery pack will give you about 25% longer run-time, but not quite as much power.
ELECTRONIC SPEED CONTROL
FLIGHT BATTERY
Because the flight battery is small and it powers both the motor and the radio system, we suggest using an Automatic Delta
Peak Charger such as the Promax Activator Digital Peak Charger (part # 885650) to charge the flight battery. It is vital to
the Hawk EP's flying performance that the battery pack be fully charged every flight, so using a peak charger is very
important.

The heavy duty Scotch tape can be purchased in any drug store or supermarket. You don't have to
use Scotch brand; however, because it helps strengthen the wing, it's important that the tape have
a high tensile strength. The 3M/Scotch part number is 105.
