Brushless Motor Requirements

If installing the Great Planes 63-62-250kV RimFire out-
runner brushless motor (GPMG4795), you will also need
to purchase:
❏
Great Planes Brushless Motor Mount Extra
Large (GPMG1265)
❏
Great Planes SS100 100A Brushless ESC (GPMM1870)
❏
9- to 12-cells (3 or 4 11.1V packs) 3200mAh
LiPo Batteries:
❏
Great Planes LiPo 11.1V 3200mAh 20C Discharge
w/Balance (GPMP0623)
❏
Great Planes Series Deans U 2 to 1 Adapter (GPMM3143)
❏
(2) Great Planes Velcro
1" x 6" (GPMQ4480)
❏
LiPo compatible battery charger such as the Great Planes
™
PolyCharge4 DC only 4 output LiPo charger (GPMM3015)
❏
Great Planes ElectriFly Equinox
Balancer (GPMM3160)
❏
Great Planes Charge Lead Banana Plugs/Deans Male
Ultra (GPMM3148)
The included spinner adapter nut is designed specifi cally to
fi t into the tapered prop nut used on the O.S. 1.60 FX glow
engine. Because of this, an adapter nut must be purchased
to work with the RimFire prop adapter. You can use Tru-Turn
Adapter Kit O.S. 1.08 (TRUQ3065) or Dave Brown X-Long
Adapter Nut 3/8-24 (DAVQ6324). Both of these adapter nuts
require a 10-32 spinner bolt that will need to be purchased
separately. The length of the bolt will depend on the adapter
nut being used. We suggest purchasing a 10-32 x 2-3/4"
[70mm] spinner bolt and cutting it to the necessary length.
Another option is to purchase the nut and prop washer
set for the O.S. 1.60 FX engine, O.S. lock nut set 1.60 FX
(OSMG6688). Using the O.S. prop nut will allow you to
also use the adapter nut included with the kit as well as the
included 5mm prop bolt.
Note: The total recommended voltage for the LiPo battery
pack confi guration is 33.3V to 44.4V. This can be done in
combinations of battery packs ranging in voltage. Be sure
that the capacity (mAh) of all packs used are the same value
(example: do not mix 3200mAh packs with 5000mAh packs).
The battery pack combination should be connected together
using the recommended series adapter. The actual quantity
of adapters needed depends on the number of packs being
used. Each adapter will connect two packs together in series.
If three 11.1V packs are joined to make 33.3V, two series
adapters will be needed (one series adapter will join two
11.1V packs together to make 22.2V, and the second adapter
will combine that 22.2V with the remaining 11.1V pack for a
total of 33.3V). If four 11.1V packs are combined for a total
of 44.4V, then three series adapters will be needed. Other
voltage combinations may require more or fewer adapters.
The recommended hook and loop material is used to join
the individual battery packs together, securing them onto
® Hook & Loop material
™ LiPo Cell
the battery tray, and securing the ESC to the ESC tray.
One package of Great Planes hook and loop contains
12" [305mm] of material. We suggest purchasing at least
two packages.
The recommended PolyCharge4 will charge up to four LiPo
packs simultaneously. A set of charge leads is required for
each pack that you plan to charge simultaneously. We suggest
purchasing a set of charge leads for each battery pack used
in the power system. The PolyCharge4 is a DC-only charger,
so a suitable DC power source will also be required.

Gas Engine Requirements

The fuel tank included with this kit is suitable for use with
glow fuel. However, if using a gas engine, the fuel tank
must be converted to work with gasoline. This can be
done by purchasing a Sullivan #484 Gasoline/Diesel fuel
tank conversion kit (SULQ2684), two packages of Du-Bro
#813 1/8" [3.2mm] I.D. fuel line barbs (DUBQ0670) and at
least 3' [914mm] of gasoline compatible fuel tubing (such
as Tygon). Without the fuel line barbs, some types of gas-
compatible fuel line may slip off the metal fuel tubes. If the
Sullivan conversion kit is not available, the Du-Bro #400 gas
conversion stopper (DUBQ0675) and one package of K&S
1/8" [3.2mm] soft brass tubing (K+SR5127) could also be
™
used to make the conversion.
Also, the hardware needed to mount a gas engine to the
fi rewall is not included with the kit. The hardware that is
detailed in the building instructions of this manual for mounting
the Fuji-Imvac BT-43 EI-2 engine includes four 10-32 x 1-1/4"
[32mm] SHCS, four #10 fl at washers, four #10 lock washers
(split washers), and four 10-32 blind nuts. This hardware
can be purchased at a hardware store, home center, or your
hobby supplier.
Choose the propeller that is appropriate for the power system
you are using. If installing the Great Planes 63-62-250kV
RimFire out-runner motor, the propeller choice will depend
on the battery voltage being used. A 9-cell (33.3V) pack
will require a 20" x 10" prop (APCQ2200). A 12-cell (44.4V)
pack will require a 18" x 8" prop (APCQ3010). If installing an
O.S. 1.60 FX glow engine, we recommend using a 18" x 6"
W prop (APCQ1806). If installing the Fuji-Imvac BT-43 EI-2
engine, we recommend using a 20" x 8" prop (APCQ2080).
