Note: Motors from other manufacturers may work with the 
Extra 330S EP ARF. However, the included fi rewall  pieces 
are designed to work specifi cally with the Great Planes 
motors listed.

Propeller

If using the Ammo brushless in-runner motor with 4.5:1 gearbox 
or the RimFire brushless out-runner motor, we recommend a 
10" x 7" E Slo-Flyer electric propeller (GPMQ4123).

ESC (electronic speed control)

A brushless ESC (electronic speed control) is required for 
this plane. We recommend using the Great Planes Silver 
Series 35A Brushless ESC 5V/2A BEC (GPMM1830).

Battery Pack

The Extra 330S EP ARF has been tested with 11.1V LiPo 
packs ranging from 1250mAh to 2100mAh. Order numbers 
are provided for packs of this size. The lighter 1250mAh pack 
is suggested for maximum performance.

 Great Planes LiPo 1250mAh 11.1V 20C Discharge

 w/Balance 

(GPMP0609)

 Great Planes LiPo 1500mAh 11.1V 20C Discharge

 w/Balance 

(GPMP0613)

 Great Planes LiPo 2100mAh 11.1V 15C w/Balance

 BP2100 

(GPMP0721)

Note: Do not use Great Planes LiPo 1500mAh 11.1V 
3S 8C Discharge (GPMP0831). This battery pack is not 
capable of supporting the current draw of the recommended
power systems.

Also, if using a 1250mAh battery pack combined with the
brushless out-runner motor, avoid prolonged full throttle 
fl ying since the current draw of the motor exceeds the 
continuous maximum current draw rating of the battery pack. 
The 1250mAh battery pack is capable of supporting shorter, 
full throttle maneuvers.

Charger

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

  Great Planes ElectriFly

 Equinox LiPo 1 to 5 Cell Balancer 

(GPMM3160)

A suitable charger is also required. The Great Planes 
PolyCharge4

 is designed for LiPo packs only, but is able 

to charge four LiPo packs simultaneously. 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 both are provided as follows:

 Great Planes PolyCharge4 DC Only 4 Output LiPo

 Charger 

(GPMM3015)

or

 Great Planes ElectriFly Triton2 DC Comp Peak

 Charger 

(GPMM3153)

Required Adhesive & Building Supplies
