Spread the plans out on your work surface, cover
them with a clear plastic material, such as the
backing from a roll of MonoKote or plastic wrap,
and commence construction.
III. RADIO SYSTEMS
Our prototype PHASOARS have been tested and flown
using two radio types from different manufacturers.
The first of these radio systems is the one
depicted on the plans. The system consists of a
standard-sized 6-channel receiver (AIRTRONICS
#92262), three micro-servos (AIRTRONICS #94501) and
a standard-sized, internally-mounted switch harness
(AIRTRONICS #97001). Power is supplied to this
system by a 4-cell SR 300 mAh battery pack, fitted
w i t h an AIRTRONICS connector. The servos have been
fitted w i t h the 4-arm servo output arms, w i t h three
of these arms cut-off and the remaining arm trimmed
as shown on the plans.
These three servos drive the rudder, stabilator and
the ON/OFF micro motor switch.
The radio system just described is very acceptable
in terms of weight and reliability!
The transmitters we've used in conjunction with the
above system were the AIRTRONICS Championship
Series 6-channel and the AIRTRONICS SR Series 4-
channel. Both of these worked well. whatever
system you choose, we suggest that the minimum
requirement is servo-reversing ability.
The second radio system that we've used is made by
FUTABA. This radio system has sophisticated
features that work well in the PHASOAR. First,
when using this system, your servo count goes from
three to two. because the receiver also houses a
fully-proportional, motor controller. Secondly,
the receiver and servos are powered by the motor
battery pack, thus, eliminating the need for a
separate, on-board battery supply for these
components! This means that there is no need for
a micro-switch, the wood mounts, the hardware to
mount these parts and no need for the arming switch
because the FUTABA system has a l l of these
components b u i l t - i n . This system is available w i t h
FUTABA's #S-133 servo included. The S-133 servo
has almost the same dimensions as the AIRTRONICS
#501 servo, thus no adjustment to the plans in the
servo area is required. Lastly, this system
includes FUTABA's Attack-4 transmitter which is
equipped with servo-reversing.
FUTABA's System #4NBL 133MN 72 designates the radio
which w i l l provide all of the components just
mentioned.
For comparison, the airborne weight of the FUTABA
system is 3.25 ounces. The AIRTRONICS system
described earlier, with the micro-switch, mounts,
hardware and arming switch weighs or 5.93 ounces.
The difference amounts to 2.68 ounces, or nearly a
10% loss of weight for the model which uses the
FUTABA system!
There are other systems that would also work in the
PHASOAR.
Have whichever radio system selected available for
sizing and fitting purposes during construction.
IV. MOTOR AND PROPELLER CHOICES
The PHASOAR has been designed and engineered to be
powered by the ASTRO FLIGHT 035 Cobalt motor, using
direct drive. This motor is relatively small,
light-weight (about 130 grams), very powerful for
