In early March of 2000, I was completing the details
for building and finalizing the plans for my first twin, the
Remmington Burnelli model RB -2. Already, during my childhood
(in the 30's), my brother and I were fascinated by airplanes
and eventually became accomplished scratch model builders. In
recent years, to our gratification, we both have also become
accomplished RC flyers. As we continued to seek that special
subject to build over the years, we were increasingly
attracted to the rare and more inventive designs.
In the early eighties my sister-in-law
offered me an old 8X10 photo of an unusual twin-engine biplane
out of the mid-twenties. I immediately recognized that it
should be a very good applicant for a twin project some day.
Hand printed on the bottom of the picture was
"Remmington-Burnelli Transport - 1925". I wrote the
Smithsonian Archives Division on two occasions for any
information relating to this subject and twice received a
package of photocopies and newspaper articles. Late last year,
I searched for "Burnelli" on the internet and found a website:
"www.aircrash.org" with fascinating information on the
Burnelli "lifting body" designs fueling the fires of interest
and intrigue.
A successful first flight after many hours of
research, design and building is all one really expects of a
project - however adding the real story involving Mr. Goodlin
and the "Rocket," the Burnelli story, and the several Burnelli
supporting new EMAIL friends has made this project a most
gratifying experience and the project of a lifetime. This is
the story of that experience.
By the end of April 2000, the new twin was
completed and ready to have the engines run. One engine was
started, trimmed for a reliable idle and strong full throttle
then shut down. The second engine was started and trimmed also
and then both were run and final trimmed to be synchronized at
full throttle. BEWARE! Once you have run a pair of twin
engines and listened to them in synch from idle to full
throttle, you may instantly become hooked on twins for it is a
totally unique and contagious experience.
As a first flight can be very exciting and
have its surprises and disappointments, I contacted my flying
buddy Ed Perls and said, "I'm heading to the field with the
Burnelli"! Ed's immediate reply was "oh boy - see you at the
field".
FIRST FLIGHT
- Very briefly we filled both 10
oz. fuel tanks, checked the onboard battery voltage and
started the engines. With the engines running we checked each
channel for proper operation (ailerons, elevator, rudder and
throttle) and the engines were once more tuned for a reliable
idle and synchronization at full throttle. With the
preliminaries completed we taxied out into take off position
and rechecked all moving surfaces for correct operation and
with all systems go, the engine throttle was increased to
about 2/3 rds. power.
First, let me tell you about the model: it is
a standoff scale model of the Remmington Burnelli model RB -2.
It is approximately 1/12 scale and has a wing span of 76",
cord 10", weight 9.6 lbs., twin K&B .45 Sportster engines,
each with a 10 oz. fuel tank and is of built up balsa and some
light plywood. The fuselage is 1/8 sheet balsa covered and the
model final covered with Century 21 heat-shrink plastic
covering. I chose these engines as the head and piston may be
rotated 180 degrees so the exhaust / mufflers exit their
respective side (left engine left side - right engine right
side) with no loss of power.
As the engines strained in synch, the big
bird began rumbling down the grass runway --- as the speed
increased she bounced a few inches and settled, then bounced
again and settled, and with a third bounce and more up
elevator she was airborne. The climb out was gradual, smooth
and deliberate --- a right turn almost completing a full
circle, a left turn and a right turn, then left turns onto
downwind leg, base leg, and onto final approach.
With engines throttled back the bird dropped
rather quickly but up elevator and she flared out and settled
in floating gently back onto the grass runway once more with a
nice run out.
As left turns are standard procedure after
take off from our field, Ed admitted following the flight that
he really believed the Burnelli was in trouble, however the
right turn was into a light breeze, rather than turn left into
a cross breeze and thus avoiding a possible wing stall at the
lower climb out airspeed. Our knees were still knocking and
hearts pounding following the successful first flight
touchdown and we were a couple of kids again. Triumphant, we
packed it in and headed for home.
Not knowing just what to expect, I was elated
with the good stability and the somewhat slow and deliberate
handling characteristics which I attribute to 1) the gentle
sweep back on each wing providing dihedral effect and 2) the
additional stabilizing effect from the lifting body feature
also significantly enhancing stability. The late Vincent
Burnelli determined that close to 50% of the total lift was
provided by the lifting body feature.
Nearing completion, I
realized I needed to determine its original colors and again
contacted the Smithsonian. They replied that "we believe the
fuselage to be of medium blue and the wings and tail
aluminum" and to my
surprise they also sent the address of the Burnelli Co. with
the suggestion I contact them directly, which I did. A few
days later I received a letter specifying the same
color-scheme as described by the Smithsonian and signed
"Chalmers H. Goodlin". In mentioning Mr. Goodlin's name to my
modeling friend Ed, he responded "oh yes, that must be "Slick"
Goodlin, test pilot of the famous Bell X-1 "Rocket" from the
late forties". Indeed - this was the case! There was so much
more to this project than simply building a model!
SUBSEQUENT
FLIGHTS - On the
second flight she was on the climb out and the right engine
quit - as the "bird" began to turn gently to the right my
heart began to pound, however I was able to correct with
rudder and flew her back to a good landing on the runway. On
the fourth flight she was on a long climb out into a bit of a
breeze and over a tree line when the left engine quit and in
attempting to hold altitude to clear the trees she rolled and
went into a diving spiral with the good engine full throttle
and into the hay field adjacent to the tree line. I really did
not want to look at
the resulting damage but I was elated, as
it was beyond belief, to find the bird without even a
noticeable scratch and validating the claims made regarding
the inherent safety of the Burnelli lifting-body technology.
In the subsequent flights I have had many engine failures and
being new at twins have had success with flying only about
half of them back onto the relatively small grass runway
primarily due to occurring at low altitude on climb out. Two
of the engine outs occurred near a one story farm building on
take off and actually flew behind the building and out of
sight - in both cases the bird settled into the alfalfa
(following over 100 yards of blind flight) maintaining it's
single engine powered glide path. The engine failure problem
was solved by using propellers with a larger pitch resulting
in more pull and running the engines richer in fuel feed. I
have not had one engine "out" since, have adequate pull on two
engines and should maintain altitude better on one engine
. In addition, the lower RPM provides a
more realistic sound and it is easier to synchronize the
engines.
The RB-2 is very stable with one engine out
and will pull to the out engine side slowly, so applying a
little rudder to the side of the running engine and having
sufficient altitude one can fly it back to the runway with
ease.
VINCENT BURNELLI
- Having recently become
aware of the life long desire and dream of the late Vincent
Burnelli to provide the flying passenger a safer passage
inherent in all of his "lifting body" designs, I think of him
each time I learn of a plane crash and the many related
victims. After flying a scaled down model of a Burnelli RB-2
lifting body design, and considering Mr. Goodlin's description
of his experiences while piloting an original CBY-3 (a later
Burnelli lifting body design) which match my experience to
whit: the gentle, stable and excellent low speed flight
characteristics, I am convinced current flight can and must be
made considerably safer by applying the basic principles of
the Burnelli "lifting body" and I highly recommend that
everyone visit the "www.aircrash.org" website to learn the
complete Burnelli story and just why we do not have today's
skies filled with safer, superior "Burnelli" airliners.
Nevertheless, when I had completed the first
flight successfully, I believed the project to be completed,
however, little did I know that the real project was just
beginning.
SHOW TIME - LAMS meet Tunkhannock, PA - I had
never taken a model to an open meet before but already had the
feeling this subject would draw considerable attention. Being
my first, I was very excited with the anticipation of
displaying the newly completed Burnelli model. As I had
received several 8X10 photos and informational sheets from Mr.
Goodlin, I prepared a display board reflecting the original RB
-2 freighter including my original photo, a display of Vincent
Burnelli's many key patents being applied today and some of
his later designs, reference to website www.aircrash.org and
finished it with a framed plexiglas front. The informational
display is placed alongside the model and the stage is set.
I quickly found the "bird" (as Mr. Goodlin
often refers to her) attracts everyone from serious scale
enthusiasts, to the curious, to young bright-eyed children as
she is so unusual and strangely attractive - perhaps some
people subconsciously recognize the simplicity and natural
validity of this design principle? I cannot describe how
rewarding and fulfilling it is to answer the many questions
and in promoting the genius of the late Vincent Burnelli. I
was so elated with the interest created by the model at the
first meet that I began plans to attend additional local
meets.
WAYMART WINGS Memorial Fun Fly
- at "Lum's"
(Vladmir Kellachow Sr.'s private airstrip) The field is
immaculate, the crowd enthusiastic and growing, and the
weather is perfect. The first hours before noon the RC models
fly between arrivals of real aircraft and skydiving
demonstrations while the kids trim up their rubber powered
models. The afternoon is alternating rubber band competition,
RC flying, skydiving, aircraft departures and arrivals and
abundant food and soft drinks. With a total estimated
attendance of between 300 to 400, this first time memorial
funfly, in memory of the late Vladmir Kellachow Jr., was a
great success and again the Burnelli received much attention.
RHINEBECK, NY
- now this is really prime
territory as it is a very large meet where real WWI aircraft
are flown and the models are limited to scale model entries of
1939 or earlier with most primary attendees being history and
scale modeling buffs. From time to time we heard several :
"Look! A Burnelli!" or "Look at this one" and most read the
display with intrigue then studied the model. I am convinced
that after describing the flight characteristics, several are
now interested in building the RB-2 when the plans become
available.
OUTSTANDING SUBJECT - I highly
recommend building the RB -2 to anyone favoring biplanes and
generally comfortable with flying models as it exhibits all of
the following favorable characteristics; stronger and roomier
fuselage, ultra stable flight, very gentle handling with
deliberate
flight characteristics even with one engine out,
and a longer glide with lower air speed and with absolutely no
stall tendencies. A scale model of a Burnelli lifting body
design will attract attention wherever it is displayed and I
believe that all of the several Burnelli designs will exhibit
the foregoing positive flight characteristics due primarily to
the ingenious "lifting body" influence.
I wish to thank my
brother Scott Heim for his patience, guidance and for his
contagious love of flight, Jessie Frees for the rare old
photograph making this project possible,
the Smithsonian
and especially Chalmers H. Goodlin (test pilot extraordinaire,
outstanding crusader for safer flight and Grand Champion of
the Burnelli "lifting body" design) and Ernest Zavala (author
and researcher) for providing extensive support and incentive
and in putting my
project in proper historical perspective, Ed Perls
(photographer) for support on and off the field, and Judy, my
dear wife and perpetual supporter, for her patience,
understanding and mostly her enduring tolerance of the hobby.
I also wish to extend due appreciation to Walter Purdy of the
Keystone RC Aero Sqdn. for his guidance and support and "Lum"
and Gary Pozza for making possible and creating the Waymart
Wings club as a means for interested youngsters to experience
the joys of flight.

of the past but it also can lead to the future.
