This section describes the items you will need to purchase for your new P-51 Reno Racer EP. These suggestions are not
set in stone, but they should provide you with a good starting point.
SECTION 1: OUR RECOMMENDATIONS
IMPORTANT
When choosing accessories for your P-51, such as servos, ESC, and receiver, 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 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 0.19 ounces and have a torque rating of no less than 7.0 ounces per square inch.
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 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.
What Electronic Speed Control Do I Use?
The ESC you choose should be capable of handling 10-15 amps continuous current. Again, lighter is better. Your ESC
should weigh no more than 1 ounce including the wiring and switch.
Note: Although a 10 amp ESC may work with our recommended battery, motor and propeller, it is at the low end of the scale.
Since some customers may wish to experiment with other motors, batteries and propellers, chances are a 15 amp ESC will
then be necessary because of higher current draw; therefore, we recommend just starting with a higher-capacity ESC.
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 10 amps. Through much testing on this
power system, we have found the 8 cell 800Mah 5/4AAA NiMH battery pack delivers the best performance in terms of
weight, power and duration. You certainly could use NiCD battery packs - they will give you more power, but they are
heavier and offer much less duration than NiMH batteries. Depending on how you fly the airplane, the trade-off between
higher weight and less duration may not be worth the extra power.
Note: At the time of this writing, NiMH batteries cannot withstand current draw about 10 - 12 amps. If you use our included 380
size motor and 5 x 2.5 propeller, current draw will not be a problem. However, if you experiment with larger propellers or
different motors, the current draw may be too much for NiMH batteries. If this is the case, you will need to use NiCD
batteries in your airplane. NiMH battery technology is evolving quickly, so in the future they may be compatible with
high-draw power systems.
