#5010 muffler for O.S. 1.60 FX engine (OSMG2846)
❏
Fuji BT-32S R/C gas engine (FJIG0033)
Per the IMAA Safety Code, magneto spark-ignition engines
must have a coil-grounding switch on the aircraft to stop the
engine and prevent accidental starting. The switch must be
operated manually (without the use of the transmitter) and
be accessible by the pilot and assistant. For use with the
Fuji engine shown, the manually operated switch was made
from a .3 amp slide switch, 16-gauge wire and a covered,
crimp-on connector purchased at the local Radio Shack
®
.
Slightly different hardware may be required if using a
different spark-ignition engine. All of the components
required are available at any hardware or home-
improvement store.
If using the Fuji BT-32SB engine the following hardware
must be purchased separately:
❏
(4) 1/4-20 x 2-1/4" or 1/4-20 x 2-1/2" Phillips-head bolts
❏
(4) 1/4-20 blind nuts
❏
(4) 1/4" flat washers
❏
(4) 1/4" lock washers
❏
(4) 10-32 x 3/4" socket-head cap screws
❏
(4) #10 lock washers
Note: If using the Fuji BT-32 (or most other gas engines),
the nose-gear option may not be used and the model must
be built as a taildragger. This is because of the extended
distance from the firewall that the engine would have to be
mounted in order to clear the nose gear hardware.
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), a package of Du-Bro #813 1/8"
[3.2mm] I.D. fuel line barbs (DUBQ0670) and 3' of Great
Planes gasoline fuel tubing (GPMQ4135). 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 12" [300mm] piece of K+S 1/8"
[3.2mm] soft brass tubing (K+SR5128, box of 5) could also
be used to make the conversion. Full instructions on how to
set up the fuel tank and make the conversion to gas are
provided in this manual.
The model on the kit box cover is shown with a Great Planes
2-3/4" [70mm] aluminum spinner (GPMQ4555) (not included).
An adapter nut for mounting the spinner cone is also required.
(Order No. OSMG4588 for use with the O.S. 1.60 FX.) The
Great Planes spinner is intended to be used on engines that
have a threaded crankshaft–not engines that use a propeller
bolt (such as most gas engines). In this case, a different type
of spinner will have to be used. In most cases the propeller
cutouts in the cone will also have to be enlarged. A rotary tool
with a carbide cutter works great for the rough work, followed
by a small metal file to clean up the edges. Always wear eye
protection when working with power tools.
A building stand or cradle comes in handy. We use the Robart
Super Stand II (ROBP1402) for all of our projects in R&D.
The Giant Big Stik ARF is intended to be flown with flaps using
a radio with a minimum of five channels. If, however, you have
only a four-channel radio, the Giant Big Stik ARF could be
flown without flaps. In this case, the flap servos will have to be
linked to the aileron servos using Y-connectors. Then, all four
control surfaces on the wings will function as ailerons.
Since the Giant Big Stik ARF is a large model, standard
servos should not be used to operate the control surfaces.
Servos with a minimum torque rating of 50 oz-in are
