ADDITIONAL ITEMS REQUIRED
This is a partial list of items required to finish the Pitts
Special that may require planning or decision-making
before starting assemble. Order numbers are provided
in parentheses.
Radio Equipment
The Pitts Special requires a minimum 4 channel radio
system such as the Futaba
®
4VF (FUTJ62**). Due to the
aerobatic capabilities of this model aircraft we strongly
recommend that servos with a minimum of 50 oz.-in. of
torque be used.
You will also need other extensions and Y-harnesses. These
requirements will differ based on the manner in which you
configure your set-up of this model aircraft. For example, you
can set this model aircraft up with two aileron servos only on
the bottom wing and mechanically connect those ailerons to
the ailerons in the top wing with connecting rods. Using the
four aileron servo set-up will take more extensions and Y-
harnesses.
Also you may opt to not use a Y-harness set-up on your
elevators by using a mixing function on your transmitter if it
has those capabilities. The extensions needed will also vary
based on the location of your battery pack and your receiver.
So be sure to plan your set-up carefully. Then, based on your
decisions, you can determine what items you will need.
Engine Recommendations
The following engines are recommended and have been
tested for use in the Pitts Special:
O.S.
®
1.60 FX two-stroke (OSMG0661)
O.S. 1.60 FX-FI two-stroke, fuel injected (OSMG0662)
SuperTigre
®
G-4500 two-stroke (SUPG0270)
O.S. FT-300 Gemini Twin four-stroke (OSMG1250)
US Engines
™
41cc 2.5 Gas Engine (USEG0041)
Remember that this is a scale model that is intended to
fly at scale-like speeds, so throttle management should
be practiced.
If you choose a lighter weight engine you will need to add
nose weight to achieve the proper balance. This model has
been tested with the lighter weight OS 1.60 FX plus added
weight to balance. This combination flew very scale-like and
aerobatic. Should you wish to minimize the total weight of
your model, you may want to consider moving the servos
from the tail location forward into the area behind the fuel
tank and just inside the bottom wing. Of course, you will need
to connect the servos to the control surfaces with pushrods
that are not installed or supplied. This option would allow you
to balance the model properly with less weight added to the
nose of the model.
