This section describes the items you will need to purchase for your new Extra 330L EP. These suggestions are not set in
stone, but they should provide you with a good starting point.
OUR RECOMMENDATIONS
Here's What We Used to Finish Our Extra 330L EP:
P/N 759118 Hitec 555 Micro Receiver
Hitec Dual Conversion FM RX Crystal
P/N 444045 Cirrus CS-09 Micro Servos (3)
P/N 128486 Wattage IC-30A Micro ESC
7 Cell CP1300SCR NiCD Flight Battery
P/N 130108 Wattage PF-12 AC/DC Peak Detection Charger
P/N 625085 Dean's Ultra-Plug Battery Connector
P/N 869020 Dubro Double-Sided Tape
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 11.0 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 no less than 30 amps continuous current. Again, lighter is better.
Your ESC should weigh no more than 1 ounce including the wiring and switch.
What Flight Battery Do I Use?
Through much testing with this power system and airframe combination, we recommend using a Sanyo 7cell CP1300SCR
flight pack. The CP1300SCR pack is ideal because it will provide superior runtime without any significant weight
penalty. We do not suggest using NiMH battery packs. At this time they cannot handle the current draw of this power
system.
IMPORTANT
When choosing accessories for your Extra 330L EP, 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.
IMPORTANT
The part number listed for the Cirrus servos is compatible with all radio control systems. This servo uses a universal connector. The
part number listed for the Hitec 555 Micro receiver is compatible with Hitec radio control systems. This receiver is also available for Futaba, JR and
Airtronics radio control systems. The Wattage IC-30A Micro ESC is compatible with Futaba, JR, Hitec, Airtronics-Z and others.
When you purchase the Hitec 555 Micro receiver, you must also purchase a Hitec brand crystal compatible with the receiver. The crystal
must also be on the same frequency as your transmitter.
Note that the Hitec 555 Micro receiver uses a dual conversion FM
Hitec crystal.
Note:
To minimize current loss, we suggest
soldering the motor wires directly to the ESC.
We also suggest replacing the stock Tamiya
connector that is likely preinstalled on your ESC
and flight battery with a more efficient Dean's
Ultra-Plug battery connector.
