We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it. Therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.

Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.

DECISIONS YOU MUST MAKE

This is a partial list of items required to fi nish the ElectroStik
EP RXR that may require planning or decision making before
starting to build. Order numbers are provided in parentheses.

Radio Equipment

The ElectroStik EP RXR requires a minimum 4-channel
radio system.

• 6" [152.4mm] servo extension for the aileron servo

Battery & Charger Options

The Great Planes ElectroStik EP RXR is designed for use
with LiPo (Lithium-Polymer) batteries only. All LiPo batteries
require a charger specifi cally designed for charging LiPo
batteries. The use of a charger not designed for charging
LiPo batteries will result in damage to the batteries and
possibly a fi re. We recommend the use of the Great Planes
Triton

2 DC Peak Charger (GPMM3153) or for charging more

than one battery at a time, the ElectriFly

PolyCharge4

(GPMM3015). The Great Planes Triton2 charger will only
charge one pack at a time, but is capable of charging NiCd,
NiMH, LiPo, and lead acid batteries. Order numbers for the
battery packs are provided below:

• Great Planes LiPo 3200mAh 11.1V 20C Discharge
w/Balance

(GPMP0623)

Note: A cell balancer is required for the LiPo battery pack
listed above.

• Great Planes ElectriFly Equinox

LiPo 1 to 5 Cell

Balancer

(GPMM3160)

POWER SYSTEM

The ElectroStik EP RXR is powered by a RimFire

C42-40-

1000kV with a Great Planes 11" x 8.5 propeller designed
specifi cally for electric fl ight. The provided Electronic Speed
Control unit is a Great Planes SS-45 brushless ESC.

The ElectriFly SS-45 brushless ESC features a brake
function that is useful for some aircraft, but is unnecessary
for this model. The factory default setting is “BRAKE OFF”
but if you notice that the motor stops abruptly when you shut
down the throttle, the ESC will need to be re-programmed.
This is something that you can easily do by following these
simple steps:

1. With the power “OFF” to both the transmitter and airplane,

move the transmitter throttle stick to full throttle position.

2. Turn the transmitter “ON,” connect the motor batteries

to the ESC, and turn the plane’s receiver “ON.”

3. After 5 seconds the motor will beep once.

4. Move the transmitter throttle stick toward you to the

“throttle down” position. The motor will beep once.

5. Again, move the transmitter throttle stick to full throttle.

The motor will beep once more to confi rm the brake is now
“OFF”. Once the brake is set, it does not require resetting
once the ESC has been switched “OFF.”

When turning off the system, always turn the receiver “OFF”
fi rst, followed by the transmitter. Once the motor is “armed”
always remain behind the arc of the propellers until the
batteries are disconnected.
