5. If you are not an experienced pilot or have not fl own this type 
of model before, we recommend that you get the assistance 
of an experienced pilot in your R/C club for your fi rst fl ights. 
If you’re not a member of a club, your local hobby shop has 
information about clubs in your area whose membership 
includes experienced pilots.
6. WARNING: The cowl and wheel pants 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 
(wheel pant, cowl) 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 Proud Bird
that may require planning or decision making before starting 
to build. Order numbers are provided in parentheses.
Battery Recommendations
The recommended battery for the Proud Bird that meets EF1
rules for maximum voltage and weight is:
❍ FlightPower LiPo Pro50 4S 14.8V 2550mAh 50C
(FPWP5041)
In addition to a battery, a LiPo battery charger is also required 
and there are several that will work (depending on your budget 
and requirements). A safe, economical charger is the Great 
Planes ElectriFly Triton Jr DC Computer Charger. TheTriton 
Jr will require a DC power source as well as a Great Planes
Equinox™ LiPo Cell Balancer in order to safely charge LiPo
batteries. If wall charging is a priority, an AC 12-Volt power 
source must also be purchased separately. A suitable power 
supply for the PolyCharge4 is the Great Planes 12V 12A DC 
power supply. Some pilots prefer to have several batteries 
and charge them faster so they can fl y more. For charging 
up to four batteries faster at the same time, the Great Planes 
PolyCharge4™ DC-powered LiPo charger is recommended. 
Like the Triton Jr, the PolyCharge4 does not have an internal 
LiPo cell balancer which is a critical component in making sure 
your LiPo batteries charge effi ciently and evenly. So, for each 
LiPo battery you wish to charge simultaneously, one Great 
Planes Equinox™ LiPo Cell Balancer will also be required. 
Finally, the PolyCharge4 does not have AC capability, so if 
wall charging is a priority, a separate AC 12-Volt power source 
must also be purchased separately. A suitable power supply 
for the PolyCharge4 is the Great Planes 12V 12A DC power 
supply. Part numbers for the products mentioned here are:
❍ Great Planes ElectriFly Triton Jr DC Computer
Charger (GPMM3152)
❍ Great Planes PolyCharge4 DC 4 Output LiPo Charger
(GPMM3015)
❍ Great Planes ElectriFly Equinox LiPo Cell Balancer
(GPMM3160)
❍ Great Planes 12V 12A Switching DC Power Supply
(GPMP0901)
Radio Equipment
Three micro servos are required for the Proud Bird. Futaba
S3115 micro servos are shown in the manual. S3102 micro
servos can also be used.
❍ Futaba S3115 Micro Precision Servo (FUTM0415)
❍ Futaba S3102 Aircraft Micro Metal Gears Servo 
(FUTM0034)
Motor Recommendations
The O.S. .25 brushless motor is shown in the assembly
instructions of this manual. Also recommended is the RimFire 
35-45-1200 motor. A 60A minimum ESC is also required. We 
recommend the Castle Creations Ice Lite 75A ESC. If using 
the recommended ESC, you will also need to purchase a male 
Deans Ultra connector. Part numbers for these recommended 
components are provided below.
❍ O.S. .25 Brushless Motor (OSMG9525)
❍ RimFire EF 1 35-45-1200 Motor (GPMG4630)
❍ Castle Creations Phoenix Ice Lite 75 25V ESC 
(CSEM7000)
❍ W.S. Deans

(2) (WSDM1302)
The Proud Bird is not just for racing. It is a very capable
sport plane and fl ies well using a more conservative power 
system. Part numbers for the recommended sports setup 
are provided below:
❍ Great Planes RimFire .15 35-36-1200 Outrunner
Brushless (GPMG4620)
❍ Great Planes Silver Series 45A Brushless ESC 5V/2A
BEC (GPMM1840)
❍ Great Planes Bullet Adapter 4mm Male/3.5mm
