IN THE MID-1930s, RC models became the basis for the Army Air
Corps’ development of aerial targets for antiaircraft gunnery training.
Starting in 1935, Radioplane of California developed several variations
of movie star and modeler Reginald Denny’s original designs.
As I have attempted to illustrate in the last few months, Reginald
Denny’s pioneering efforts led to the first military contract for radiocontrolled
drones being awarded to his Radioplane Company.
At the expense of his movie career and financial well-being, he and

his associates spent numerous days and nights perfecting a drone to the
point at which it could be demonstrated and subsequently ordered. For
his efforts, Reginald Denny is justifiably referred to as the father of
Remotely Piloted Vehicles (RPVs).
When I first planned for this series of columns, I was well aware of
Reginald Denny’s involvement in model airplanes, from his hobby
shop to his kits and his distribution of Dennymite engines. His
pioneering involvement in RPVs came as a complete surprise to me
and probably to many of you readers.

The Control Systems: The early radio-control equipment that
Reginald Denny and his associates used was highly sophisticated for
its time but incredibly primitive compared to modern gear.
The earliest appears to have been single-channel regenerative (not
super heterodyne), utilizing stepping relays or even telephone-dial
equipment. In this system, the signal was turned off and on to activate
a mechanical device that moved a control surface one step at a time.
One push of the control button gave right rudder and a second push
gave left, with a pause in between. Movement was full travel and
therefore anything but proportional in any way.
RPV systems slowly evolved following the same general
development patterns as the radio-control systems we hobbyists used.
Space Control introduced the first commercial multichannel
proportional equipment in 1958! This and
similar gear sold for what was the equivalent
of a month’s salary for many modelers.
Unlike hobbyist gear, however, the
military radio equipment was notable for
placing an emphasis on reliability and
durability at the expense of weight and
compactness. The photos of a typical
transmitter and receiver, on display in the
AMA museum, reveal how bulky and
complex designs can get following military
specifications.
Of course, this equipment was designed
well in advance of the transistor or integrated
circuit. That may not be as far in the past as
one would think; the early production B-52s
used tube-type electronics, which were later
replaced with much smaller and more reliable
transistorized equipment during updates.
Compare the equipment in the photos to
contemporary gear and its comparatively low
prices to appreciate what the last 60 years
have brought forth in RC! Today’s equipment
totally exceeds even our wildest dreams of the 1950s or earlier.
Reliable, compact, and not very expensive—it’s a minor miracle!
Smokey Hole: One of the more dominant gunnery/bombing ranges in
the Air Force inventory is fewer than 100 miles from where I am
writing this. Smokey Hill Army Airfield was built in the 1940s as a
crew training facility for B-29s, joining the Pratt, Great Bend, and
Walker, Kansas, facilities a few months after their completion.
Among my older Air Force friends, the place was less than
affectionately known as “Smokey Hole,” associated, no doubt, with
the severe teething pains, as previously related, of the early B-29s and
the base’s later use, postwar, to train B-47, B-52, and B-58 crews.
Prelaunch, note use of electric starter on cart and three-wheel launching dolly.
RPV pilot seated on tower flies with a stick unit. The man wearing
the earphones is in touch with the down-range crew.
Before radar-directed fire, drones were so seldom hit by gunners
that a certificate was presented to those who did so.
The field’s name was changed to Schilling Air Force Base in the
early 1950s and was later closed to become the Salina Municipal
Airport. However, the gunnery range 15 miles to the west of the old
base retains the old Smokey Hill (a local river) name, and it remains
open to this day.
In the 1950s, the drone used at Smokey Hill was the Radioplane
OQ-19D, which weighed 350 pounds and was constructed from
aluminum. It spanned 8 feet and was powered by a McCullough O-
100-1 two-stroke, air-cooled, four-cylinder engine, enabling speeds of
200 knots at sea level. These were maintained and flown by the 802nd
Air Division of the 40th Bomb Wing of Strategic Air Command
(SAC).
The mighty little OQ-19D made it interesting for the gunners of B-

29s, B-47s, and into the B-52 and B-58
programs. Nearly all gunners in SAC went
through a two-week gunnery course on
temporary duty. They quickly learned that
the little drone was exceedingly difficult to
hit—so much so that a special award was
presented to anyone who did so by aim or by
accident.
Until fairly recently, the Smokey Hill
gunnery range was littered with the remains
of numerous target drones, but a salvager has
removed them. The drones were launched
from a center-pivot tether system, which
enabled them to travel around a circular
launch pad until they gained flying speed.
They then sped off tangentially under the
control of an operator seated in a tower
behind the line of gun emplacements and
turrets. Gunnery ranges do not have runways.
Look at the photo and notice the threewheel
takeoff dolly, which was tethered to a
center pivot. The drone accelerated
(apparently clockwise) in a circular pattern
until it lifted off and dropped the dolly. It
sort of looks as though some Air Force types
had watched modelers fly CL Speed events.
One can only speculate what Reginald
Denny must have felt as his early RPV
efforts evolved into today’s jet-propelled
supersonic targets, surveillance vehicles, and
guided ordnance. It’s certainly a vast leap
from his early radio-controlled model
airplanes, but is directly related and a living
memorial to Denny.
Oddity: This has been such an interesting
series of columns that it was difficult to find
an adequately spectacular way to end them.

finish.
For many years, Tom Ames has flown
RC at our flying field. His models are lovely
to behold, his flying is top-notch, and he is a
friendly and delightful young fellow. I
consider him a cherished friend.
When Tom isn’t flying models with us,
he slips into a telephone booth and changes
into an Air Force lieutenant colonel. His
previous assignment was facility commander
of Smokey Hill gunnery range! Considering
what I’ve been writing about in the last
months, this is rather strange. MA
