6. While this kit has been fl ight tested to exceed normal use, 
if the plane will be used for extremely high stress fl ying, such 
as racing, or if a motor larger than one in the recommended 
range is used, the modeler is responsible for taking steps to 
reinforce the high stress points and/or substituting hardware 
more suitable for the increased stress.

WARNING:

 The fuselage, wheel pants, and canopy hatch 

included in this kit are made of fi berglass, the fi bers of which 
may cause eye, skin and respiratory tract irritation. Never 
blow into a part to remove fi berglass dust, as the dust will 
blow back into your eyes. Always wear safety goggles, a 
particle mask and rubber gloves when grinding, drilling and 
sanding fi berglass parts. Vacuum the parts and the work 
area thoroughly after working with fi berglass parts.

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 Cirrus SR22 

ARF that may require planning or decision making before 

starting to build. Order numbers are provided in parentheses.

Radio Equipment

The Cirrus SR22 ARF requires a minimum 4-channel radio 

system with four nano servos such as the ElectriFly ES-50 
nano servo. In addition, two 12" [305mm] servo extensions 
and a dual servo extension are required for the aileron servos.

Motor Recommendation

The recommended motor for the Cirrus SR22 ARF is a 

RimFire

 .10 (35-30-1250) brushless outrunner motor.

❏  

Great Planes RimFire .10 (35-30-1250) Outrunner 

Brushless (GPMG4595)

If using the recommended brushless motor, a 35A brushless 
ESC is required:

(GPMM1830)

Propeller

If you are installing the recommended RimFire brushless 
motor, we suggest a 10x7E APC propeller (APCQ4123).

Batteries and Charger

One 1500-3350mAh 11.1V Lithium Polymer battery pack 

is recommended. Using a 2200mAh 11.1V LiPo, our SR22 
balanced at the recommended C.G. without the need for 
additional ballast.

A suitable charger is also required. The Great Planes 

PolyCharge4

 is designed for LiPo packs only. However, it 

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 Pb acid 
batteries. Order numbers for both are provided below:

Pilot

If you wish to use the same pilot that is shown in the building 
instructions, purchase Williams Brothers 1/8 Pilot Bust Kit 
Sportsman (WBRQ1130). This pilot fi gure requires fi nish 
sanding and painting, and some additional modifi cation  of 
the pilot fi gure is described in the building instructions.
