When choosing accessories for your PT-19 Cornell 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.
SECTION 1: OUR RECOMMENDATIONS
What Motor, Speed Control and Flight Battery Combination Do I Use?
The airplane is designed for use with a 370 size gear drive electric motor or other gear drive electric motors of similar size and power
output. For good flying characteristics at an affordable price, we suggest using the WattAge 370
power system with 3.67:1 gear box and 7.5 x 5 propeller. Combined with the WattAge IC-15A Micro
ESC and the WattAge 8 cell 5/4AAA 800mAH NiMH flight battery or the WattAge 2 cell 1500mAH
LiPO flight battery, you can expect about 8 minutes or more of smooth, scale-like flying enjoyment.
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 0.34 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.
The airplanes requires three servos. One for elevator, one for ailerons and one for rudder.
What Radio and Receiver Do I Use?
You will need to use a 4 or more channel radio control 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 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.
Here's a List of What We Used to Finish Our PT-19 Cornell EP ARF:
●
When choosing the propeller and flight battery for your particular motor, double-check that the power system will not draw more amperage than
your motor is designed for.
●

When you purchase the Cirrus MRX-4II Micro
receiver, you must also purchase a Cirrus brand
crystal compatible with the receiver. The crystal must
also be on the same frequency as your transmitter.
●
The MRX-4II Micro receiver uses a 50U-compatible
micro crystal, Cirrus P/N 4462XX, XX being the
frequency number of your transmitter (e.g., if your
transmitter is on frequency number 52, the crystal you
would purchase would be P/N 446252).
