WATT AGE Super Impress II EP ARF Instructions For Final Assembly - page 4

The Super Impress II EP ARF can be flown using a variety of different power systems. Motor mount plates are included for both gear
drive motors and direct drive motors.
For slow, trainer-like performance, the airplane will fly very nicely using the Wattage 370 power system with 3.67:1 gear box and
7.5 x 5 propeller. Combined with the Wattage 8 cell 5/4AAA 800mAH NiMH flight battery and the Wattage IC-15A Micro ESC, you
can expect about 8 minutes of smooth, slow and docile flying enjoyment.
If you want more power and faster speeds, then we recommend using the Wattage Super 400 Cobalt Direct Drive motor with an
APC 7 x 4 propeller. Matched with the Wattage 7 cell CP1300 NiCD flight battery and the Wattage IC-30A Micro ESC, this power
system will provide enough power for aerobatics and impressively fast flight speeds. As an alternative, you could use the Wattage
Super 400 Cobalt Direct Drive motor with the Wattage Inline 400 Gear Box and an APC 11 x 7E propeller, along with the Wattage
8 cell 2/3A 1100mAH NiMH flight battery and the Wattage IC-30A Micro ESC. This combination will provide more vertical
performance and longer flight times than the direct drive setup.
This section describes our recommendations to help you in deciding which types of accessories to purchase for your new
Wattage Super Impress II EP ARF. Please read through this entire section very carefully. We have provided you with tips
and recommendations that, if followed, will result in a great flying airplane. Failure to follow our recommendations may
result in a poor flying airplane.

✦ When choosing accessories for your Super Impress II EP ARF, such as servos, ESC, receiver and other
related accessories, it's very important to take the weight of these items into consideration. Remember, the lighter the overall
weight of the finished airplane, the better the airplane will fly.

Many different power systems can be used to fly the Super Impress II EP ARF. Feel free to experiment with different brushless
motors, Lithium Polymer flight batteries and any of the other new and cool electric products that are becoming available.
Below we list just one of the more exciting alternative power systems we tested with the Super Impress II EP ARF. With this power
system the airplane was an absolute blast to fly!
Motor: Multiplex Permax BL-480 6D (480 size, 6-turn direct drive)
Propeller: APC 7 x 5E
Flight Battery: 3 Cell Lithium Polymer
ESC: Any brushless ESC capable of handling 25 amps or more
For longer flight time, the Wattage 3 Cell 2000mAH LiPO battery # 128783 works very well. We also used the Tanic 3 Cell
1550mAH LiPO and the Multiplex 3C 1250mAH LiPO with good success.
Alternative Power System Suggestions
The servos you use should be the lightest available, yet still have an adequate amount of torque. We suggest using servos that
weigh no more than 0.34 ounces and have a torque rating of no less than 11 ounces per square inch. Cirrus CS-4.4, Cirrus CS-5.4
and Cirrus CS-6.5 servos would be a perfect choice. Although a little heavier, Cirrus CS-09 servos and Hitec HS-55 servos would
also work well.
You will need to use a 4 or more channel radio system. The receiver should be as light as possible, preferably 1/2oz. or less. Most
four-channel micro receivers would be a good choice. We personally suggest using the Cirrus MRX-4II, the Hitec 555 Micro or the
Hitec Electron 6 Micro. If you do use one of the Hitec receivers, we suggest removing the case to reduce the receiver's weight. If
you do remove the case from your receiver, we strongly suggest wrapping the receiver with heat-shrink material to protect the
internal components.

✦ The MRX-4II receiver has a range of approximately 500 yards (~1/4 mile). Keep this in mind when flying the
airplane while using this receiver.
