Howard DGA-6 or MisterMulligan was a very successful
racer from 1930s. Mister Mulligan was most famous for
winning the Bendix and the Thompson racing trophies
in the same year with a top speed of 238.70 mph. It
was also the only racing airframe that evolved into
a commercial production aircraft.
The ElectriFly 52.5" Mister Mulligan ARF is a great
looking replica of this legendary 30s racer that is
packed with great features like working flaps, a realistic
replica radial engine, a hidden battery hatch, a variety
of fiber glass parts and all white MonoKote covering.
So without any further delay, lets put this racer together
and head out to the field to see what it is capable
Mister Mulligan ARF is shipped in a colorful and sturdy
box that looks great even just sitting on your workbench.
of the components of the ARF are individually wrapped
and taped down and there was no shipping damage to any
of the components during shipping. The huge fuselage is
taped down along the side of the box with the wings and
tail section placed in a seperate compartment in the middle
of the box.
you remove the components and place them on your workbench,
it is hard to not be affected by the size and the great
looks of the fuselage. With only a small amount of components,
this assembly should go together fairly quickly.

was known as the Howard DGA-6 at the factory,
but to everyone else, it was simply the
Mr. Mulligan. In the mid-'30s, it enjoyed
two noteworthy descriptions. First, it was
the only plane ever designed solely to win
the coveted Bendix Trophy ? and second,
it was the only plane to win the Bendix
Trophy and the Thompson Trophy in the same
year. Now, ElectriFly has recreated the

of the first things that you will grab your attention
is the advertised "hidden" hatch for the battery.
The canopy is held in place by powerful magnets and
is easily removed by pulling straight up allowing generous
access to the battery tray. The landing gear
look great and the wheel pants have already been drilled
for you. The cowl will be attached to the fuselage
with hidden screws to preserve the scale looks of
the airframe. The replica radial engine and the small
bag of plastic parts that will act as the push rod
tubes are waiting to be assembled and placed
on the airframe.

the assembly with great detail. Installation steps are clearly
documented and illustrated to help in assembling the ARF as
quickly and correctly as possible. The CG location (57mm back
from the leading edge) and the recommended control throws
are clearly documented.

bay covers are pre-marked with locations that will fit
the Futaba S3115 servos perfectly. Once you position the
hard wood blocks, it is just a simple matter of just
mixing up some epoxy and gluing them in place.
Futaba 3115 servos are mounted in place for the ailerons

aileron servo leads are routed through the wing using
the string that is already placed through the wing. I
used a 12" servo extension to bring the servo lead out

control horn locations have to be marked and drilled.
The manual recommends that you mark your drill bit so
you do not go through the top of the aileron as you drill
since the screws will not go all the way through the aileron.

the servos in place, the control horns for the ailerons
have to be installed. This is achieved by locating the
hard mount inside the aileron, then marking and drilling
the location to allow the two sheet metal screws to bolt
into the control horn backing plate on the other side.
The connection to the servo arm is then made by using
a 90 degree push rod connector.
the servos completed, the wing pieces are glued together
using epoxy. Note that the servo leads are routed through
the small holes towards the middle of the wing. If you
look inside the fuselage, there is a painted piece of
wood which will hide the electronics from sight. This
has to be removed to allow access to installing the landing
landing gear is simply bolted in place from inside he
fuselage. The addendum to the manual shows that some ARFs
might have been shipped with small pieces of tape covering
the holes which have to be removed first. Once the gear
is attached to the fuselage, the axles are bolted on and
filed flat in locations where the wheel collars will sit.
The wheels are installed between two wheel collars and
the wheel pants can be attached but the manual recommends
that you do that last so that is what I did.
tail assembly starts with the installation of the horizontal
stabilizer. This is a very easy process that involves
removing the small piece of balsa in the tail and sliding
the stabilizer in place. I used some epoxy to glue in
both stabilizers and made sure that the assembly would
dry nice and straight by clamping the wood around the
tail wheel is inserted from the bottom of the fuselage.
The L-bend of the tail wheel will protrude from the gap
that has already been cut for you allowing you to install
the rudder in place with CA hinges. Note that the rudder
is the only surface that has to be hinged as all of the
other surfaces are ready to go out of the box. With the
tail assembled, all that is left is to install the control
horns and make the connections to the servos.
elevator and rudder servo are housed inside the fuselage
and the manual recommends that you use the 90 degree locking
connectors to make the connection to the control arms.
I used a handy Z-bend pliers to make nice Z-bends instead
of the provided connectors mainly because I was not able
to get a nice 90 degree bend in the connector inside the
fuselage. The 45A ESC is then mounted to the side of the
battery tray and the R617FS receiver can be mounted inside
the fuselage. I used two Y-connectors for the ailerons
and the flaps.

replica radial engine installation is next. This is honestly
the only part of this assembly that takes a little bit
of time to do right. The hole in the center has to be
enlarged to fit over the RimFire prop adapter.
install the push rod tubes four holes per cylinder have
to be carefully drilled. The manual recommends that you
use a hobby knife to score the plastic so that you have
a nice starting point for the drill which works out quite
well in application.
all of the holes drilled, the push rod tubes are inserted
in place. I found that it was easier to insert them from
the inside and push them in place by guiding them with
my other hand. Once all of the push rod tubes are installed,
they can be glued in place from the rear of the assembly
with some CA so the glue points are not visible. The next
step involves the removal of the plastic pieces between
the cylinder heads. I used the small sanding drum of my
Dremel kit to easily remove and shape the plastic.
resulting assembly simply looks gorgeous. It can then
be glued in place inside the cowling using some medium
CA. To attach the cowling to the fuselage, the cowl has
to be glued to the wooden ring after it has been bolted
to the fuselage. To make sure you do not get epoxy on
the fuselage, the manual recommends that you mask off
the whole fuselage using the plastic that it was shipped
in. Once everything is securely masked off, epoxy is used
to attach the cowl to the ring and allowed to cure after
making sure that the alignment is correct.
resulting cowl with the ring glued in place can then be
further strengthened by applying some epoxy to the inside
of the ring. The cowl can then be bolted back in place
using the four hidden bolts. At this point, I also bolted
the wheel pants on using two bolts per side.
recommended pilot is the Great
Planes 1/5th scale sport pilot. The pilot has to be
cut down to size a little to get it to fit inside the
hatch and can then be epoxied in place. The final assembly
steps involve making the servo connections to the ailerons
and flaps and bolting the wings on. The struts can then
be screwed in place and the optional door drawn using
the template that is provided in the last page of the
maiden flight of the Mister Mulligan ARF happened to land
on a clear but windy day in Houston. We headed out to Scobee
field and performed the short field assembly which involves
making the aileron and flap servo connections, bolting the
wing on and attaching the struts. After double checking
that the control surfaces were dialed in according to the
throws documented in the manual and that the CG was within
the recommended range, we were ready for the first flight.
the field emptied out upon request for a photo shoot, we
were ready to take the Mister Mulligan ARF through the paces
and grab some nice photos of it doing so. Since it was a
windy day, I did not try to taxi around too much in fear
that the wind would flip the airframe on the ground so I
simply lined her up manually centered on the runway and
applied throttle for the first take off. As the Mister Mulligan
gained speed, it quickly lifted its tail and it was not
soon after that it started to gently lift off. I noticed
a tendency to bank right on take off which I learned to
compensate for but I was not sure if it was the airframe
or the wind that day.
later days when the wind was not a factor, I discovered
that the recommended rudder throws limits the ground steering
a little even on high rates so I decided to increase the
highest rate a little to gain better steering control strictly
when on the ground.
in the air, a couple of clicks of trim was all that was
required to get the Mister Mulligan ARF was flying straight
and true. I was actually very pleased with its performance
after a few short circuits and immediately felt comfortable
enough to bring her low over the runway for some nice photo
opportunities. I did not really discover any bad manners
worth reporting on as I put it through the paces of its
flight envelope. The Mister Mulligan ARF flew more on the
lines of sport plane rather than a hard to fly scale airframe
in my opinion as I was able to do rolls, loop and even inverted
flight without any issues.
pleased me the most about flying the Mister Mulligan ARF
was the sound the airframe made as it cut through the air
with authority. It is hard to describe but it felt like
I was flying a much larger airframe as it sped by me on
low and banked approaches. The speed that the RimFire 0.32
allows on this airframe can probably be classified as scale
like as it is fast enough to thrill,l but probably will
not be your go to plane for all out speed runs. I think
the Mister Mulligan ARF really deserves to be flown in a
scale like manner and flown low and fast to truly allow
you to appreciate the great scale looks and the sound it
makes as it carves its way through the air.
the first couple of flights, I set the timer to six minutes
to make sure I would not run out of power mid flight. On
successive flights, I was able to increase this time to
8 minutes easily. I also had some 4S5000mAh batteries on
hand which are slightly heavier than the recommended pack
which I used without any major CG issues.
far as the flaps performance, I noticed that the first time I
deployed the flaps the Mister Mulligan ARF reacted by gaining
some altitude as the manual clearly stated. However, I did
not have to mix in any flaps to elevator compensation as
the effect quickly wore off and the Mister Mulligan ARF
settled in for a nice slower flight envelope with the flaps
deployed to their max settings as recommended by the manual.
The flaps really do a good job of slowing the Mister Mulligan
ARF down for graceful landings that are very easy to perform.
out the video to see her in action!
Electri-Fly Mister Mulligan ARF (Pilots, Stills & Video: Burc Simsek and
Mister Mulligan ARF is a very nice airframe indeed. With
a short and pleasurable assembly process, it does not take
much to get the Mister Mulligan ready to fly and if you
want to go all out you should definitely spend the time
in preparing the radial engine per the manual and perhaps
even spend the extra time to detail the cylinders with some
performance of the Mister Mulligan ARF is more towards the
sport airplane territory rather than the hard to fly scale
replicas. The airframe presents very nicely in the air and
the sound it makes as it cuts through the air has to be
heard to be appreciated. It can perform many basic acrobatic
maneuvers with easy but looks the best on full throttle
low level flight in my opinion.
remember when I first saw the Electri-Fly Mister Mulligan
ARF that I was truly taken by its scale looks. After getting
the chance to assemble it and put it through its paces in
the air, I would not hesitate to recommend it to anyone
with an appreciation for scale airframes.
