CL CONTEST BOARD RATIFICATION VOTE

Single‑blade prop ban rescinded; Open B Speed pull test to 48 Gs ratified

Contest Board procedures provide for immediate enactment and enforcement of rules-change proposals that involve safety and/or an emergency. As reported in the July issue (page 90), the Control Line Contest Board voted for immediate application (effective June 1) to ban single‑blade propellers in all Speed events except 1/2A and FAI, and to increase the Open Class B Speed pull test to 48 times the model's weight.

Contest Board procedures also require a ratification vote on such emergency actions approximately four to six weeks later — items ratified become permanently part of the rules; items not ratified are rescinded as of publication notification (in this instance, September 1).

Result:

The Open Class B pull test has been 48 Gs since June 1 and continues in effect.
The single‑blade prop prohibition in Speed (except for 1/2A and FAI) was in effect since June 1; the prohibition ends on September 1 unless/until subsequent action is taken.

Votes:

Ten CL Contest Board members voted to ratify the increased pull test in Open B Speed; one was opposed (Dist. VIII).
Eight board members voted against ratifying the single‑blade prop ban; three were for (Dists. II, VI, IX).

RUBBER FOR PEANUTS

As announced in the June issue (page 89), the Scale Contest Board voted for immediate clarification of the requirement for rubber power in Peanut Scale models as follows:

"The Scale Contest Board specifies that during the development, consideration and passage of rules for Peanut Scale Events 52 and 53, it was understood by all concerned that the rules were intended for rubber‑powered models only, even though, through oversight, it was not so stated in the rule book. Therefore, it is declared that the intent of the Peanut Scale rules are that rubber‑powered models only be used, and no other type of power will be permitted, effective immediately."

This clarification was made under the Contest Board Procedures for Interpretations, Safety and/or Emergency Proposals and required a ratification vote four to six weeks after publication. Ten Scale Contest Board members voted to ratify; one (Dist. VIII) opposed. Therefore, the interpretation above is final.

RC HELICOPTER JUDGES' GUIDE APPROVED

Acting according to Contest Board Procedures for Interpretations, Safety and/or Emergency Proposals, the Radio Control Contest Board voted for immediate acceptance and use of the RC Helicopter Judges' Guide as proposed by the RC Helicopter Rules Advisory Committee (Horace Hagan, chairman).

Ordinarily, CN would print the complete new rules accepted on a quicker-than-normal basis. However, since the guide was printed in its entirety in Dave Chesney's RC Helicopters column in last month's issue (page 37), reprinting here is omitted to save space.

At the voting deadline, seven RC Contest Board members responded:

Six favored immediate acceptance of the proposed guidelines (Dists. II, IV, VI, VII, VIII, IX).
District I voted to first publish the proposal and then vote four to six weeks later concerning immediate acceptance.

Publication requirements of the Contest Board Procedures have been met with Dave Chesney's column in the September issue. With that issue expected to mail around September 1, the ratification vote by the RCCB is expected between October 1 and October 15. Anyone wishing to affect the outcome of the ratification vote, pro or con, should state views to the district Radio Control Contest Board member by October 1, 1979.

1979 FREE FLIGHT WORLD CHAMPIONSHIPS — TAFT, CA, U.S.A.

Bill Bogart, Manager

Plans are progressing well. As of July, 24 countries had indicated their intention to participate at Taft. There will be a large French delegation (26 or more), New Zealanders are coming in force, and many more competitors will arrive from overseas.

The basic fee for attending the World Championships is $200. This includes:

Shared room (October 3 through 9)
All meals (October 4 through 8)
Awards banquet on October 9
Frequent bussing to the flying site (October 4 through 8)

Breakfast and supper are served at the Bakersfield Inn (contest headquarters). Lunch will be served at the Taft flying site each day.

The basic fee was established mainly for competitors. For those who do not require the full package, individual service charges have been established. Registration is required.

Fees:

Registration: $20
Nightly lodging (per person): $5
Breakfast (4:30–5:30 am): $5
Lunch (at Taft): $5
Dinner (8–9 pm): $9
Banquet: $10
Daily bus fare: $1.00

If you want to be assured of a room at the Bakersfield Inn, send the $20 registration fee and your arrival date to Mrs. Micheline Madsen at AMA HQ in Washington. She will make the reservation for you. If your fee arrives at AMA HQ after September 29, reservations cannot be assured. Decide early.

On arrival at the Bakersfield Inn, the contest registration table will be in the lobby. There you can purchase meal and bus tickets in any combination. Pay lodging charges to the Bakersfield Inn at checkout. Lodging fees prior to October 3 and after October 9 are $16 single and $30 double.

CB INTERIM VOTES

The results printed in the August issue are correct, but in several instances the name shown for the Contest Board member was of the former officeholder rather than the current officer who actually voted. To set the record straight:

On the RC Contest Board it was Mike Mueller who voted for District VI and Bill Thomas for District VIII.
On the Scale Contest Board, Bob Underwood voted for District VI, William Irwin for VIII and Bill Stroman for X.
On the FF Contest Board, Bradley Bane voted for District II.
On the CL Contest Board, Bill Lee voted for District VIII.

RC MASTERS TEAM SELECTION TOURNAMENT

Ron Van Putte

Dave Brown took first place in the Team Finals, landing his Tiporare on its final flight of the event. Judges were lined up so that all could see the maneuvers from nearly the same point of view; this kind of arrangement, or similar, is expected for the World Champs in South Africa at the end of September.

Dave Brown is congratulated by Miss Masters Tournament as NSRCA President Jim Vanderbeck (L) and Tournament CD Ron Hasselbrock (R) share in a bit of humor.

The U.S. RC Aerobatics World Championships Team and the planes they flew (L–R): Dave Brown, Tiporare; Dean Koger, EU-1; Mark Radcliff, Phoenix 7; Don Lowe (team manager).

The 1979 United States team to compete in the World Championships in South Africa: Dave Brown, Mark Radcliff and Dean Koger. They earned the right to represent the U.S. by beating 33 other Master-class fliers on June 23–24 at Lakefield Airport near Celina, OH. Dave Brown outpointed Mark Radcliff 3453 to 3351 while Mark edged Dean Koger's 3317. Both Dave Brown and Mark Radcliff represented the U.S. in the 1975 and 1977 World Championships. Rhett Miller, the other team member for those years, did not compete in the 1979 Masters Tournament.

Celina, OH is about 75 miles north of Dayton, in a hotbed of RC Pattern flying. The Lakefield Airport (5 miles south of Celina) has a runway approx. 100' wide by 4,500' long with a flat surface and well-mowed grass. The runway was oriented east-west; contest administration was on the north side so fliers and judges did not have to look into the sun.

Weather and scheduling

Friday, June 22 (practice day): temperatures in the 80s, a few puffy clouds, light NW winds.
Saturday, June 23: upper 70s, clear skies, light-to-moderate north winds.
Sunday, June 24: early morning upper 40s, overcast, strong gusty NE winds; cleared later with temperatures into the high 60s but with strong crosswinds.

Friday's practice ended with aircraft and transmitter processing, followed by a pilots' briefing. A controversy arose over the method of determining the winner. The announced method: the best flight in front of each set of judges would be used (three sets of judges, six rounds anticipated). The alternative: use the three highest flight scores overall. After discussion, most fliers agreed the announced technique was fairer to both fliers and judges.

Review of flight scores showed the top three places would have been the same under either technique, though lower placings would have changed. There was an "easy" set of judges that influenced some competitors' throwaway flights, but no consistently "hard" set in the author's view.

Equipment and engines

Aircraft in the top 10 were varied. Only two top-10 fliers (Jim Kimbro and Don Weitz) flew the same aircraft (Deception). Other top designs included Tiporare, Phoenix 7, EU-1, Bootlegger, Tiger Tail 3, Troublemaker II, Curare, and Phoenix 8.

By far the most popular engine was the Rossi. Other engines included Super Tigre X-60, OS 60 FSR, OPS, Webra and a single YS. Nearly all engines used tuned pipes; one competitor with a muffler withdrew after the first day. Few pilots used fuel with more than 5% nitromethane. Notably, Don Weitz ran 5% nitro with 10% Klotz oil, having progressively reduced oil percentage without ill effects after consulting an engine specialist.

Popular props included Max Dailey, Rev-Up and Zinger.

Age and participation

Age was not a determinant of placing high. In the top 10 finishers, the combined ages of four fliers (Chidgey, Bonetti, Oddino, Lowe) was 19 years more than the combined ages of the remaining six (Brown, Radcliff, Koger, Helms, Kimbro, Weitz). Joe Bridi (listed age 60+) finished 12th and was gratified after previous bad luck and hand troubles.

Of the 48 fliers who qualified per the 1978 program directive, 36 flew. Many were missing due to business or family pressures; André Bouchard wrecked all his airplanes during practice week and could not compete.

Judging format and performance

Using three teams of judges on the line for all six rounds was physically demanding but seemed fairest, as each set saw every flier an equal number of times. Concern about judge fatigue if five rounds were flown on Saturday was avoided when only four rounds were flown Saturday and two on Sunday.

Judges:

Site A: Bob Reuther, John Targos, Bill Johnson
Site B: Al Tuttle, Julie Woods, Travis McGinnis
Site C: Dick Austin, John Byrne, Larry Sartor

Anecdote: During a flight at Site C, a contestant's caller ran in front of the judges to retrieve an airplane; the judges remained focused and did not turn their heads.

Dave Brown's consistently high flight scores secured his team spot early. The other two slots were decided in the last round; Dean Koger and Mark Radcliff battled for positions, with Steve Helms ultimately finishing as alternate. Mark had early contest problems (nicknamed "Four Roll Radcliff" for an early mistake) but improved under pressure. Mark was flying the Phoenix 7 and had two Phoenix 8s under construction for South Africa.

Dean Koger flew the EU-1, a large and spectacular performer that rolls exceptionally well. The EU-1 is to be kitted by Aero Composites (also kits Phoenix 8), release expected in September.

Dave Brown flew a modified Curare (Tiporare), kitted by W. K. Hobbies. Steve Helms finished only 35 points behind Dean and was the alternate. Scores were close; small changes in maneuver scores could shift placings significantly.

The Cincinnati Aeromodellers and the Western Ohio Radio Control Society handled administration. C.D. Ron Hasselbrock and Assistant C.D. Bill Elliott kept operations smooth despite commuting responsibilities.

As you read this, the U.S. team was preparing to depart for South Africa. Best wishes to Dave Brown, Mark Radcliff and Dean Koger.

(End of table)

RC MASTERS (Cont.)

Weather varied across the three days. The organizers chose the "best flight in front of each set of judges" scoring method, which many considered the fairest. The use of three sets of judges ensured each set saw every flier an equal number of times.

A review of contest flights:

Aircraft were highly individual; top pilots used a variety of designs.
Rossi was the most-used engine. Most competitors ran tuned pipes.
Few pilots used fuel with more than 5% nitromethane.
Props: Max Dailey, Rev-Up and Zinger were common.

Steve Helms finished only 35 points behind Dean Koger as alternate. Scores were tight: small changes in a few maneuver scores could change final placements. The organizing crews (Cincinnati Aeromodellers and Western Ohio Radio Control Society) and CD Ron Hasselbrock and Assistant CD Bill Elliott managed the event effectively.

Best wishes to the U.S. team — Dave Brown, Mark Radcliff and Dean Koger — for the World Championships in South Africa.

ACADEMY OF MODEL AERONAUTICS 515 FIFTEENTH STREET NW WASHINGTON, DC 20005

CL CONTEST BOARD RATIFICATION VOTE (summary)

Single-blade prop ban rescinded; Open B Speed pull test 48 Gs ratified.

Contest Board procedures provide immediate enactment/enforcement of rule change proposals involving safety and/or emergency. As reported (July issue, page 90), the Control Line Contest Board voted immediate application, effective June 1, to ban single‑blade propellers in Speed events (except FAI 1AA). The pull test for Open Class B Speed was increased to 48 Gs (48 times the model's weight).

Ratification is required four to six weeks later. As a result:

Open Class B pull test: 48 Gs since June 1.
Single‑blade prop prohibition: in effect since June 1; ends September 1 unless subsequent action is taken.

Votes:

Ten CL Contest Board members ratified the increased pull test; one opposed (Dist. VIII).
Eight voted against ratifying the single‑blade prop ban; three voted for (Dists. II, VI, IX).

RUBBER FOR PEANUTS (summary)

As announced (June issue, page 89), the Scale Contest Board voted an immediate clarification: Peanut Scale Events (52, 53) were intended for rubber‑powered models only; no other power allowed. This clarification is effective immediately and was ratified four to six weeks later (ten in favor, one opposed — Dist. VIII), making the interpretation final.

FNART — West Baden, IN (Report)

West Baden, IN, was the contest site. The historic building (built 1902) has served as a resort hotel, gambling casino, retreat for Jesuit monks and now a college for hotel management and related occupations. The atrium comprises a 300' diameter room with just under 100' ceiling height, surrounded by inner and outer rings of rooms, creating a flying area superbly isolated from external weather disturbances.

In past years many hangups were caused by a central bandstand which once lowered from the ceiling. This year the entire structure was shrouded in plastic; as a result fewer than 10 models were caught (previously several models per hour had been the norm). FNART contestants generally agree a properly shrouded atrium is a fully adequate World Championships site. Plans are being made to bid for the 1980 Indoor World Championships (in conjunction with VNART) for June 21–29, 1980.

Northwood Institute offers excellent flying conditions and good adjacent dining facilities; contestants can stay in-building for the duration of the meet. At night there is enough light from the ceiling to permit flying of all but the microfilm-covered models; it is not unusual to see models flying at any hour.

Contest format and scoring

The FNART contest format scores each model against the current AMA Cat. II record for the contestant's age class, unless the model has no record class (Scale and Easy B compete as usual). A flight score is expressed as a percentage (Index) of the record time. For example, for a 10-minute record:

9-minute flight = Index 0.900
11-minute flight = Index 1.100

This scoring has produced many Junior winners, though junior dominance is shifting as junior records climb.

Index winners (received engraved pewter mugs):

Mike VanGorder — Novice Penny — Junior — 10:44.7 — Index 1.232
Jim Richmond — AMA HL Stick — Open — 44:43.0 — Index 1.230
Mike Clem — Novice Penny — Junior — 10:40.5 — Index 1.224
Walt VanGorder — Novice Penny — Open — 12:49.8 — Index 1.149
Don Lindley — Autogyro — Open — 7:15.0 — Index 1.039
Stan Stoy — HLG — Open — 2:32.4 — Index 1.038

Notes:

A later flight was posted at 11:11.0.
A later flight series gave 2:40.2.

Notable performances

Jim Richmond: His flights demonstrated preparation and craftsmanship. He repaired a damaged model, reselected motors, and flew record times without test flights. He later re-braced a repaired F1D wing and achieved 37:52 in FAI Stick.

Stan Stoy: Set a noteworthy HLG mark with a folding-wing design (three-panel fold, 9.5' wingspan at launch). The design unfolds in flight to provide a very slow descent.

Other winners receiving pewter mugs:

Walt VanGorder — Manhattan Cabin — 9:41.8
Dirk (Dick) Obarski — Easy B — 18:52.1
Charlie Sotich — AMA Scale score 149.3 (Chicago, IL)
Jim Miller — Currie Wot Peanut Scale model

A record application for "The Oldest Existing Peanut Scale Model" (Charlie Sotich's Volksplane) may be submitted but verification is doubtful.

Easy B wing-humidity issue

Relative humidity in the atrium reached 85%. After Stan Chilton achieved an astounding 21+ minute flight, a wing-chord check failed and the flight was thrown out. Subsequent checks of other wings showed dimensional changes due to humidity. Stan conditioned his wing in an air-conditioned room for half an hour and later posted a 20:24 flight. He spent hours adjusting wing ribs and tightening covers to prevent wing "growth" in humidity.

Other records and highlights

Pennyplane: Cezar Banks and Walt VanGorder battled; Cezar set 13:55.2.
Novice Pennyplane: Mike VanGorder edged Mike Clem at the last minute.
Junior Class A ROG Stick — 9:37.4; Dave Lindley — Index 1.035
Open FAI HLG Stick — 33:24; Bucky Servaites — Index 1.022
Junior Paper Stick — 16:01; Mike VanGorder — Index 1.052

(Index of 1.052 is a winning score; no duplicate prizes were given.)
