Electric Motor Accessories

These are the items shown in the manual that were used
with the ElectriFly ™ 63-62-250kV RimFire
(GPMG4795).
❏
Great Planes Extra Large Brushless Motor
Mount (GPMG1265)
❏
O.S. 1.60 FX locknut set (OSMG6688)
❏
100 Amp ESC for brushless motors
❏

❏
(8) 3mm fl at washers (DUBQ3307)
❏
Great Planes Threadlocker (GPMR6060)

Batteries for Electric Motor Power

There may be many different battery combinations available
that will work well with the recommended brushless RimFire
motor for this model. However, following are two setups
recommended in this manual:
For aerobatics and sport fl ying the following battery, battery
adapter connectors and propeller are recommended:
❏
(3) ElectriFly 3200mAh 11.1V LiPo battery packs
(GPMP0623). The batteries will be connected in series. This
is referred to as a "9S" confi guration because it is comprised
of three 11.1V LiPo battery packs each consisting of three
individual 3.7V LiPo cells connected in series.
❏
(2) Great Planes ElectriFly Series Deans U 2 to 1
battery adapters (GPMM3143)
❏
Suitable propeller such as 20" x 10" E
(electric) (APCQ4028)
❏
®
Velcro hook & loop adhesive strips (1" x 6" [25 x 150mm],
GPMQ4480)
For all-out 3D aerobatics the following battery, battery
adapter connectors and propeller are recommended:
❏
(4) ElectriFly 3200mAh 11.1V LiPo battery packs
(GPMP0623). This is a "12S" confi guration.
❏
(3) Great Planes ElectriFly Series Deans U
2-to-1 battery adapters (GPMM3143)
❏
Suitable propeller such as 18" x 8" E
(electric) (APCQ4021)
❏
®
Velcro hook & loop adhesive strips (1" x 6" [25 x 150mm],
GPMQ4480)
IMPORTANT: Before experimenting with different battery
combinations and connecting multiple battery packs with
adapter plugs, refer to the "Battery Precautions/Connecting
Batteries" on page 33.
If using LiPo batteries, a charger specially suited for charging
™ electric motor LiPo batteries is required. The Great Planes PolyCharge4
(GPMM3015) is recommended. The PolyCharge4 will charge up
to four LiPo batteries simultaneously. If using the PolyCharge4, a
12 Volt source will also be required for powering the charger. If you
plan on charging four 3200mAh batteries simultaneously, a power
source capable of delivering at least 12.8A is required. A suitable
12V auto battery could be used, or a portable source capable of
converting 120V AC to 12V DC such as the Rivergate 15A DC
Bulldog Power Supply (RHCP2015) is suitable. If charging only
three 3200mAh batteries simultaneously, the Hobbico
Power Supply (HCAP0250) is also suitable.
ElectriFly LiPo batteries should not be charged through the
discharge connector (that is the plug that connects to the
ESC). LiPo batteries should be charged through the balance
connector via a LiPo cell balancer such as a Great Planes
ElectriFly Equinox
battery to be charged simultaneously will be required.
As mentioned in the introduction, there is a forward and an
aft radio tray for mounting the receiver, receiver battery and
throttle servo in either of two locations. There are also two
different options for mounting the rudder servos–either a
pull/pull cable setup where the servos are mounted inside
the fuselage, or a standard pushrod setup with the servos
mounted outside the fuselage under the horizontal stabilizer.
Whichever combination you choose depends partially on
your preference, but should also depend on what type of
power plant you will be using–gas, glow or electric. With gas
engines (often heavier than glow engines) it is best to locate
as much weight as possible as far aft as possible. Therefore,
if using a gas engine it is advisable to mount the rudder
servos externally in the aft location and it is virtually required
that you use the aft radio tray. Even with this confi guration
your model may still end up slightly nose-heavy and require
a few ounces of lead weight in the tail. Should you insist on
using the pull/pull rudder setup with a gas engine you can
expect to add approximately 10 oz. [280g] of lead to the tail.
With lighter glow engines such as the O.S. 1.60 FX, however,
the weight distribution won't be as lopsided, so you will have
more latitude when deciding which rudder servo and radio
tray confi guration to use. You could mount the rudder servos
however preferred, then wait to decide where to mount the
radio tray after the model has been mostly completed and
you are checking the balance point.
When it comes to electric power, in most instances–
depending on how many and what kind of batteries you are
using–the model will be the heaviest. And, same as using a
gas engine, you'll probably want to use the aft radio tray and
mount the rudder servos externally in the aft location under
the horizontal stabilizer.
