The Ammo motors are labeled to provide the
most information at a glance. For example: the
36-50-1500kV is 36mm in diameter, 50mm
long and has a kV (rpm-per-volt) of 1500 rpm.

The ElectriFly Brushless Large Motor Mount
combines the ease of installation with the
adjustability to fit most motor applications. The
Large Motor Mount is designed to fit the bolt
pattern of the Great Planes .60-1.20 Nylon
Engine Mount. This easily allo ws the conv ersion
of a glow powered plane to electric powered.

GEARBOX PROPELLERS

The ElectriFly Ammo motors have high kVs
meaning that they like to run at very high rpm.
A gear drive is used in order to reduce the rpm
allowing a larger, more efficient propeller to be
used. Great Planes ElectriFly offers a 36mm
Large Gear Drive (GPMG0515) with several
pinions that allow for the following gear ratios:

Spur Gear GPMG0668 ........70 tooth

GPMG0672 ........90 tooth

Pinion Gear GPMG0637 ........14 tooth

GPMG0643 ........20 tooth

Low Ratio> 6.4:1, 5:1, 4.5:1, 3.5:1 <High
Ratio.

If you use a prop that is too small with a gear
ratio that is too low , the motor will dra w v ery little
current and the prop will turn at too low of an
rpm to produce any usable power. The higher
the gear ratio, the smaller the prop will need to
be and the higher the rpm will be. If the gear
ratio is too high for the prop used, the motor will
draw excessive current and overheat.

The 36mm Large Gear Drive is designed to fit the
Great Planes Large Motor Mount (GPMG1260).

PROPELLER ADAPTERS

The 36mm Large Gear Drive uses a 6mm
prop adapter. If you will be using the 36mm
Ammo Motor without a gear drive, it requires
a 5mm prop adapter.

There is a wide selection of propellers available
for electric use. The 36mm Ammo Motors use
high performance electric props such as the
APC E-series props. The larger the propeller
used, the more current your motor will draw.
The smaller the propeller, the less current the
motor will draw.

Shown are a few of the recommended electric
props. Due to the large range of propellers
and the constant addition of new sizes, visit
our web sites at www.electrifly.com and www.
greatplanes.com for the most up-to-date listing
of electric type props.
