was able to maiden the Superstar EP a few times when it was rather
calm and later flew it twice for the video in some wind. All four
times, the stock setup worked very well with my only complaint
being rather short 5 minute flights. The plane glides well and
lands easily without power. The plane steers well on pavement
take-offs as long as the power is kept high.
the video, the winds were about 10mph. We took off pavement and
landed in grass due to the rather short parking lot runway. The
Superstar EP had no problem looping or rolling. The plane is designed
to be a stabile trainer so it doesn't really care for inverted
flight as it tries to upright itself. The lazy rolls (in fact
all rolls) were done with aileron, rudder, and elevator control.
The EP RTF Select version comes with ailerons.
the stock Superstar EP in action!
I really liked this plane for some relaxed flying in the evening,
I decided to try several hop-ups on my Superstar EP.
I increased the wheel size from the stock 1-3/4" to 2"
and finally to 2-1/2". My 2" wheel upgrade didn't feel
quite large enough and the wheels I had found at home were poor
quality so I decided to buy some Du-Bro 2-1/2" (250SL) Super
Lite Wheels with tread. The center holes were too big for
my Superstar gear mains so I used some 5/32 diameter round aluminum
tubing for inserts.
goal here is to improve landings and allow take-offs on grass.
With my Jeti Phasor motor upgrade, it should easily take off from
ordered a Jeti
Phasor 30-3 brushless inrunner motor from Hobby Lobby as a
powerful maintenance-free replacement of the stock Speed 600 motor.
An inrunner is like an outrunner in that it is a direct drive
solution but there is no spinning can so it can be mounted right
in place of the Speed 600 motor using the same stock mount. The
Jeti Phasor weighed 0.3oz lighter than the stock Speed 600 motor
also tested the stock setup using a 2-cell Kokam 3.2AH Lithium
pack before trying my Jeti Phasor motor and the weight reduction
combined with the higher voltage under load provided a noticable
increase in power. The 3200mAh pack capacity gave me an increase
of 1-1/2 times the flight duration.
Jeti Phasor 30-3 motor mounted perfectly. I could even secure
the front to the stock aluminum mount using two M3x10mm screws
although this is not necessary. I also used a Jeti 40-amp ESC
with BEC and a 5mm prop adapter that I had with a red spinner.
Hobby Lobby also sells 5mm prop adapters and spinners, if needed.
tested the power system with my 3-cell Kokam 3.2AH pack and measured
280 watts at 25amps using an old Kyosho 9x6 nylon prop. Nothing
in the power system is being stressed at that current level so
even though full throttle will provide spectacular performance,
you could leave the stick at full all day long without over-heating
anything. Note the connector style change to Dean's Ultra to properly
handle the higher current.
with the 3-cell Kokam 3.2AH pack that has the equivalent voltage
to a 10-cell NiCd pack, my Superstar was RTF at 3oz under stock
weight (45oz/2.8lb) which is almost 1/4lb drop. My new power level
is now a powerful 100w/lb which will provide strong aerobatics!
test flying my new power system using a pavement takeoff, the
tail would often spin out when trying slower more scale takeoffs.
I decided that my modified Superstar needed one last hop-up.
used an RA1300 Complete
Tailwheel Assembly from Hobby Lobby to easily create a steerable
tailwheel. By simply drilling a hole through the fuselage tail
so that the metal wire was in line with the rudder leading edge,
I made a few bends and epoxied it to the rudder. The tailewheel
base fits in a custom cut groove and is held by the two supplied
that the actual position of the drilled hole was 2-1/4" from
the rear fuselage tip and not where shown in the photo with the
drill. After the epoxy had dried, I recovered the rudder bottom
with some white Monokote.
my new power system provided superb power and flight times, it
was time for my second video! The wind was 0-5mph for this video.
We took off pavement and grass that was rather long. It was not
a flying field but rather an office park in need of a mow. The
hop-ups really made my Superstar EP a great all around flyer with
plenty of power and a 15-20 minute flight time with aerobatics
or 25 minute relaxed flying.
