Both AMA events flown on Thursday use
tuned pipes to generate higher power. They
are also flown on the single control system
called monoline. The A Speed event uses
.15-size piped engines for power.
Models in this class often reach speeds in
excess of 190 mph. To slow the models
down, the line length was increased from 60
feet to 65 feet.
Californian Jerry Rocha again took first
place by setting a new record on his first
flight at 188.78. His backup flight was at
186.46 mph. Second place went to Chris

Montagino at 180.81 mph. Third went to the
MNM team at 179.84 mph.
All contestants in the event placed
official times. First place in Junior A Speed
went to James VanSant at 133.98 mph.
In the past the B Speed event often saw
models exceed 200 mph. The event took a
double hit when the lines were lengthened to
70 feet and high nitro was eliminated. Speed
fliers have yet figured out how to overcome
these changes and as a result speeds are
nowhere near those of the past.
Third place this year went to the MNM
team at 146.64 mph. The team used all of
its attempts to reach this speed. Charles
Whitler flew his upright pipe-equipped
model to second place with a speed of
159.22 mph. First place went to Bill
Hughes who flew his OPS engine-powered
model to 168.47 mph.
Three contestants were unable to place an
official flight. James VanSant placed first
in the Junior Division at 137.66 mph.
The North American Speed Society
(NASS) again sponsored Sport Jet flying
on Thursday as a provisional event.
Turnout was heavy and many successful
flights were placed.
This year first through third places went

design created by the late
Lenny Waltemath called the
TARFU. The sidewinder
design showed itself to be a
very stable design in the high
winds that blew all day during
the event.
In the top four places the
Bailey Sport Jet engine
powered two models and the
Jet Bill engine powered two.

First place at 155.38 mph went to Bill Capinjola, builder of the Jet
Bill engines. Second place went to Jim Rhoades at 149.94 mph using
a Bailey engine for power.
Third went to Dave Mark who used a Bailey to power his
TARFU. Glenn Lee placed fourth flying his all-metal model powered
by a Jet Bill engine.

CL Carrier
Thursday dawned with a light breeze
that had grown to a wind by the time
flying started. After we had been flying
for an hour, the wind was even
stronger—at one point reaching an
average of roughly 20 mph with gusts
well above that.
With the wind and some equipment
problems early in the day that kept
many of the early fliers from posting
complete scores, Profile Carrier
presented a challenge that few of the
13 competitors were prepared for. In
fact, there were seven flights before
Art Johnson managed the first 100point landing of the day.
There were only three landings all
day that earned the full 100 points.
Within the first hour, Bob Frogner, Art
Johnson, and John Vlna all managed

complete flights and posted scores that put them one, two,
three in the standings.
Bob’s occurred on his second attempt after being blown
backward coming into the wind on his first flight. John Vlna
also managed his complete flight on the second attempt.
After that, the increasing wind took its toll, and there were
only two other landings the rest of the day.
It is interesting to note that four of the five models to
complete landings were Bill Calkins designs: two Guardians
and two Sea Vampires.
Bob Frogner’s winning flight was with his de Havilland
Sea Vampire. Art Johnson flew a Grumman Guardian and
John Vlna flew his Ki-76.
In Sportsman Profile Carrier, sponsored by the Navy
Carrier Society, there were two entrants completing flights.
Howard Olson (Wisconsin) flew a Calkins Grumman
Guardian to first place and Dave Hull (California) flew a
Perry-designed MO-1. This was the first Carrier Nats for
both Howard and Dave.
—Richard Perry
Bob Frogner’s de Havilland Sea Vampire lifts off on the
flight that would carry Bob to first place in the Profile
Carrier event. His early flight held off all challengers as
the wind increased through the day.

Bonita designed by Bill Melton. It has a two-piece
fuselage to facilitate shipping from Phoenix to
Muncie for the Nats.
Takeoffs with at least 12 mph headwind were the
easiest part of the flight. Not a single model failed
to get airborne. Howard Olson’s Guardian is on its
way to first place in Sportsman Profile Carrier.

CL Racing
Wednesday was a very busy day
and Thursday made up for it with
a small turnout for both Rat and
Texas Quickie.
Rat started the day with a 70lap qualifying race for Bob
Whitney from Florida and Steve
Eichenberger from Arizona. This
year, after a couple of years of
trial, the rules for AMA Fast Rat
were changed to limit the engine
size to .15 cu. in.
It has taken several people this
much time to sort out the new
formula and develop competitive
equipment. But Bob Whitney
went a different route: using an
F2C diesel-powered Team Racer.
Steve Eichenberger’s
beautiful 15-powered
Fast Rat.
What Bob found is that the superior reliability and
pitting of the F2C equipment often makes up for a
lack of ultimate airspeed.
Contrasted to Bob’s diesel-powered rig, Steve
Eichenberger has developed a conventional Rat
using an inverted .15 engine and minipipe. Steve’s
model is a beautiful example of what a Rat can be
and is very fast, but its Achilles heel proved to be
problems in
restarts during the
pit stops. In his
70-lap qualifying
race, Steve was
able to overcome
this problem and
turned a 2:54.92
compared to
2:56.19 for Bob.
However, in the
140 lap final,
Bob’s better pit
stops prevailed,
yielding a final
time of 6:02.95
while Steve
turned in a time of
6:18.36.
Real modelers live here!
Texas
Quickie Rat, an
NCLRA event, followed Fast Rat. Most notable
for this event was the absence of nearly all past
winners. In the first feature race, Dave McDonald
piloted Bob Oge’s entry and turned in a Natswinning time of 7:02.94. Also in this race, Mike
Ron Duly shows off his very
nice modified Scorpion Texas
Greb ran a 7:09.28—good for second overall. In
Quickie Rat.
the second feature race, Ron Duly from Southern
California flew his beautiful
modified Scorpion—a Dave
McDonald design—to 7:20.32.
One aspect of TQR is the strict
rules on venturi and needle-valve
body dimensions. In addition,
engines may be modified by
removing material but not adding.
After the conclusion of the
races, the three top finishers had
their engines inspected for
compliance. Venturis were removed
and measured with a bore gauge,
and the needle-valve bodies mic’ed
for diameter. All engines were
within the specs for the event.

Fast Rat winners (L-R) are Jason Allen who piloted for Steve
Eichenberger; Bob Whitney and pilot Dave Hallas; and Dave
Betz.

CL Stunt
The winds of central Indiana blew a little gentler yesterday
morning, but the air began to take its toll soon after the first
round judges’ break. Many of the early round fliers were able
to reconcile the lower scores flown on Wednesday.
Who goes on is determined by a great flight on Wednesday
and a similar, but hopefully better flight on Thursday. For
those who were bitten by the wind demon on Wednesday, they
could only hope to regain their own self-respect with a couple
of good flights on Thursday. My own confidence returned
with a more complete flight in the morning.
At least two more models bit the dust Thursday. One of the
Brazilians took a quick exit during his first-round flight.
Another flier on Wednesday tipped a propeller and walked his
model to the fields north of the “L” pad and put it down safely
in the low-grown beans. Applause rang out as he saved his P47.
During his Thursday flight, Windy Urtnowski’s new model
went inverted as planned and the plug came unlit as not
planned. This could happen to anyone, but over the asphalt
surface of the “L” pad, the apprehension factor is at its all
time high with the pilot.
Windy too, searched for the softer pillow of the grass or
beans but within a rotation or two, his outer wing came in
positive contact with an object just off circle four. The
resultant crash broke off the outer wing and autopsied his
carbon fuselage.
Final tabulations were not written on the scoreboard as this
column is being written. Now the Advanced pilots and the
Open competitors are moved to their own respective circles.
Advanced will determine who the winner is in that class
today, Friday, July 13.
The Open Class fliers will choose from the field of 20 the

Sunday afternoon.
Windy’s Novanta
became rekitted on
Thursday when the
fire went out while the
model was inverted over
the asphalt on the “L”
pad. Subsequent
movement to place the
model over grass or
beans failed when the
outer wing cut a swath
through an immoveable
object on the sidelines.

best five to fly Saturday morning for the Open Finals and the Walker
Cup Fly-Off. The Walker Cup is determined in a fly-off between the
best Junior, Senior, and Open pilot at this year’s Nats.
The PAMPA meeting went smoothly and lasted only some 40
minutes. The executive meeting at 6 p.m. was only a brief overview
of the main meeting.
Vast United States Postal Service rate changes and the rising costs of
printing have begun a search to cover the costs of mailing Stunt News
to US members and those in foreign countries. No paid subscription
is covering any of the printing and mailing costs. Several proposals
were presented to the gathering for their possible future ways of
cutting costs or raising dues.
Warren Tiahrt and Shareen Fancher were lauded for their unselfish
work and service to PAMPA. Warren will be retiring and Paul Walker
has volunteered to fill his shoes for three years or more. Paul also
“hinted” that more former Nats winners and top-draw fliers should
give and return the favor of working at the Nats instead of flying in it
all the time.
Congratulations to Shareen’s and Warren’s retirement.
—Allen Brickhaus
Bruce Perry of Canada carries his model to
Circle 2 for an official flight on the “L” pad. Bruce
is a fine fellow and an excellent Stunt flier.
An unknown Brazilian flier is looking toward the
bean field soon after he tipped a prop. This is a
safer way of getting to the ground under these
conditions.
