This section describes our recommendations to help you in deciding which types of accessories to purchase for your
new Wattage MiG-15 EDF.
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 poorly flying airplane or an airplane that doesn't fly at all.
SECTION 1: OUR RECOMMENDATIONS
What Servos Do I Use?
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 0.22 ounces and have a torque rating of no less than 7.0 ounces per square inch. Cirrus CS-10
servos or Hitec HS-50 servos would be a perfect choice.
What Receiver Do I Use?
The receiver should be as light as possible, preferably 1/2oz. or less. Most four-channel micro receivers would be a good
choice. If you plan on using the Hitec 555 Micro receiver, we suggest removing the case to reduce the receiver's overall
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.
Important Note:
We don't suggest using short-range receivers like the Hitec Feather or Cirrus MRX-4. The range
provided by these receivers will not be long enough for you to keep control of the airplane.
What Electronic Speed Control Do I Use?
The ESC you choose should be capable of handling 15 - 20 amps continuous current. Again, lighter is better. Your ESC
should weigh no more than 1 ounce including the wiring and switch.
Important Note:
Although a 15 amp ESC may work with our recommended battery, motor and fan unit, it is right at
the low end of the scale. Since some customers may wish to experiment with other motors and batteries, chances are
a 20 - 30 amp ESC will then be necessary because of the higher current draw; therefore, we recommend just starting
with a higher capacity ESC. Also, some 15 - 20 Amp ESCs don't support the use of more than three servos. If you
choose to install the optional nose gear steering on your MiG-15 EDF, you will then be using four servos. Check the
specifications of the ESC you choose to make sure it will support the use of four servos.
Important Note:
When choosing accessories for your MiG-15 EDF, such as servos, ESC, receiver and accesso-
ries, 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.
What Flight Battery Do I Use?
To get good flight performance you need to use the right type of flight battery. You need a flight battery that can
deliver enough voltage and be able to handle current draw up to approximately 15 amps. For the best performance
we suggest using the new Wattage 10 cell 1100Mah 2/3A NiMH flight packs. These flight packs work very well in this
application, providing as much power as 2/3A NiCD packs and about twice as much flight time. If you don't want to use
NiMH flight packs, good quality NiCD flight packs will also work well. We have had good success using 10 cell 600AE
flight packs and 10 cell 500AR flight packs.
Important Note:
At the time of this writing, the majority of NiMH cells available do not produce the voltage
necessary, nor can they withstand the high current draw experienced with high-draw ducted fan motors. Our
optimized NiMH cells are the only ones we know of that do. We don't suggest using just ordinary NiMH cells in this
application, because poor flight performance will likely result.
