The following section describes our recommendations to help you in deciding which types of accessories to
purchase for your new Wattage Thermalaire EP ARF. We have tested all of these items with the airplane and
found that these products will offer the best in performance, reliability and economy.
RADIO SYSTEM
MOTOR CONTROLLER
OUR RECOMMENDATIONS
Focus 3 AM
P/N 128471
To operate the motor, we highly suggest using a propor-
tional electronic speed control (ESC) that features
battery eliminator circuitry (BEC) and auto-cutoff. BEC
allows you to eliminate the receiver battery and uses the
flight battery to control both the motor and the radio
system. Eliminating the receiver battery provides a great
weight savings which effectively increases performance.
The auto-cutoff feature turns off the motor when the volt-
age in the battery drops too low to operate the radio
system safely. This guarantees safe operation throughout the entire flight. To obtain these features, we suggest
using the Wattage IC-380 30A ESC. If you decide not to use a proportional electronic speed control, an elec-
tronic switch like the Hitec Motor Controller SP-1003 (part # 759850) is an economical way to turn the motor
on and off. This switch does not offer any proportional speed, only off or full power.
The Thermalaire EP ARF will require a minimum 3
channel radio control system that includes two stan-
dard servos. The radio system we recommend is the
Hitec Focus 3 AM radio. This radio system includes
two standard servos, receiver, servo mounting hardware
and a setup guide. If you already own a radio system,
or want to purchase a radio system that will be more
upgradeable in the future, a four or more channel radio
with two standard servos will work fine. If you decide
to go this way, our recommendation would be to use
the Hitec Flash 4X FM Computer radio. This is a very good radio system that offers the capability to grow as
your experience grows. A standard size receiver will fit in the Thermalaire EP, so the purchase of an after-
market micro or mini receiver is not necessary.
FLIGHT BATTERY
The battery you choose should be a 7 cell (8.4Volt) Nickel
Cadmium battery pack. Choose a battery pack between
1100Mah and 2000Mah. A premade R/C car battery such
as the Trinity 1400Mah flat pack works very well. A 6
cell battery pack will fly the Thermalaire EP; however,
climb out will be slower than if you use a 7 cell pack.
Today's new generation of Sub-C 3000Mah Nickel Metal
Hydride batteries also performs well, but requires a linear charger featuring adjustable peak cutoff voltage.
