Remember: Take your time and follow directions to end
up with a well-built model that is straight and true.
If you’re an inexperienced modeler, we recommend that
you get assistance from an experienced, knowledgeable
modeler to help you with assembly and your first flights
.
You’ll learn faster and avoid risking your model before you’re
truly ready to solo. Your local hobby shop has information about
flying clubs in your area whose membership includes
qualified instructors.
You can also contact the national Academy of Model
Aeronautics (AMA), which has more than 2,500 chartered
clubs across the country. Through any one of them,
instructor training programs and insured newcomer training
are available.
Contact the AMA at the address or toll-free phone number

This is a list of items required to finish the BLT that must
be purchased separately. For some of these items there
is more than one option which will require a bit of decision
making ahead of time. Order numbers (in parentheses)
are provided for your convenience.
Radio Equipment
The BLT requires a micro receiver and two micro servos.
Futaba
®
S3103 (FUTM0037) or Hobbico
®
CS-5 (HCAM0090)
micro servos are suitable.
Speed Control
An electronic speed control with BEC (Battery Eliminator
Circuitry) is required. The BEC allows both the motor and the
radio system to be powered by the same battery (thus
eliminating an additional battery typically required to power
the radio). The Great Planes ElectriFly
™
C-5
Nano
High
Frequency Electronic Speed Control (GPMM2000) is
recommended for the BLT. If you purchase the complete
motor and gear drive system, the speed control is included
(refer to the
“Motor System”
section that follows).
Motor System
The BLT is designed to use the Great Planes ElectriFly T-
280GD ESC motor system and gear drive for electric
flight (GPMG0430). This system includes a T-280 Ferrite
Motor, S-280 4.1:1 ratio gearbox, 3mm prop adapter,
APC 10 x 4.7 Slow Fly propeller and the ElectriFly C-5
Nano
High Frequency Electronic Speed Control w/BEC.
The same components are also available without the
speed control by ordering number GPMG0445.
Battery recommendations
There are mainly two kinds of battery packs used for
electric R/C models; nickel-metal hydride (NiMh) packs,
and nickel-cadmium (NiCd, pronounced
ny-cad
) packs.
NiMh batteries are recommended for the BLT because
they provide nearly twice the capacity of a NiCd for their
size. However, it should be noted that nickel-metal
hydrides cannot be charged as fast as NiCds.
Each individual cell that makes up a battery is 1.2 volts.
Simply stated, a volt is the amount of
power
a battery
pack can deliver (a 6-cell battery pack is 7.2 volts).
Batteries are also rated by their capacity in mAh (milli-
Amp-hours), or how much energy they store. A 550 mAh
battery can supply 1
Ampere
for .55 hours (about
30-minutes). A 1200 mAh battery pack is about twice the
size of a 550 mAh battery pack. These are the battery
packs recommended for the BLT:
Panasonic 6-cell 550 mAh NiMh pack
(GPMP0100) for
beginners due to its light weight.
Panasonic 7-cell 550 mAh NiMh pack
(GPMP0101) for
advanced pilots who are capable of flying in slightly
windier conditions. (Continued on page 4)
DECISIONS YOU MUST MAKE
NOTE
: We, as the kit manufacturer, provide you with a
top quality kit and great instructions, but ultimately the
quality of your finished 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.
