Outstanding report and I wish I could have been there.  I'm sure there was a lot of strategy discussed by all on "how to" for next time.  Thanks for keeping us informed!!!

RUBBER PAYLOAD CONTEST - AUGUST 14TH


If not the best attended OFFC contest it was certainly one of the most fun.  Everyone agreed that we will have to do this one again.  There were only two entries, Bill Watson and Jim Leuken.  Now, that may not sound like much of a contest but everyone there was fascinated and many more will participate the next time. Bill and Jim took two different approaches to the problem.

Bill took the high camber airfoil approach.  His model was sturdy but only weighed 10 grams and had a low wing design reminiscent of a 1930s ROG model.  He installed a small keel, under the wing, to attach the clay payload, keeping the CG centered.  His motor was 1/8” flat, tan rubber, as required by the rules, and the final motor weighed 2.4 grams. The last flight lifted 25.6 grams of clay.

Jim’s approach was a high winged, contemporary ROG type model with a pylon, tip dihedral and an airfoil with a very small camber.  He wrapped the clay load around the pylon to maintain the CG position.  His last flight, with essentially the same motor as Bill’s model lifted 25.3 grams of clay and might have lifted more except he ran out of time.

This contest was more closely fought than would appear with only two contestants.  The biggest problem was getting the heavily laden models to turn inside the gym.  There were many flights that did not lift off and became high speed taxi runs.  Several flights did not make the 20 second minimum (leading to an observation that ’20 seconds can be a long time’).   And, of course many flights ended against the wall.  Hitting the ceiling was not an issue here.

This contest was a successful experiment and it was agreed that the next time there will be many more contestants.

The next contest is Comet Phantom Flash, plan stock except for thrust button, prop shaft and prop, on August 28th.

On Wednesday, July 31, the Dime Scale Contest (9 cent scale) was held in the Stonehurst gym.  We had a great meeting before the contest which ended with a few surprised, "The contest is today?" remarks.  As it turned out only three people brought dimers.  But, following the FAC three contestants makes a contest rule it went ahead anyway.

Bill Watson brought a freshly made Heath Parasol.  Joe Whiting brought a SIPA S.11 (French Arado 96) and a Fokker DXVII.  Don Butman brought his SB2C-3 and a Howard DGA-15.  Once Bill got the Heath trimmed it was evident that he would win the contest.  Joe's Fokker had been finished the night before the contest and was in need of more trimming that could be done that morning so he flew the reliable SIPA S.11.  Don's SB2C-3 was beautifully stable in flight but he couldn't get over 30 seconds out of it so he switched to the DGA-15.  (Although he held the more colorful Curtiss for the photos.)

The contest was for the best single flight of unlimited (well, completed before the 11:30 cutoff time) attempts.

The results:

  • 1. Bill Watson         80.3  seconds
  • 2, Joe Whiting        52.41
  • 3. Don Butman       36.1

The next contest is the Rubber Payload Contest on August 14.

Also, for those who enjoy a challenge, the OFFC Payload contest will be at Stonehurst on August 14.  See attached poster.

OFFC  contests are open to all interested modelers.

Stonehurst Rec center is at 9901 Dronfield Ave, Sun Valley, CA 91352.  It's one of those hidden parks so you will have to Google Map it to see how to get there.

The OFFC meetings start at 9:00 AM and the flying sessions are 10:00 to 12:00.

I was at the Predicted Time/Spot Landing contest yesterday.  This is the OFFC's one outdoor contest that is always held in the middle of summer on the Stonehurst Recreation Center field.   It was a bit windy but flyable. The contest is open to any rubber powered model that can ROG (Yes, in the past helicopters have been entered!)  You have four flight attempts, each. to accomplish two tasks.   The flight for, either task. must be at least 15 seconds to count. The two tasks may be accomplished by a single flight.

The first task is predict the duration of your model's flight before launching your model from a card table.  The second task is to get the model to land as close to an American Flag on a pole in the middle of the field.  The pole has a 50 foot measuring tape attached to it for measuring the distance from the pole to the closest part of the model.

An interesting variety of models was flown, the usual Minnows, a few designed for the contest models and for those without anything to fly, Dave Gee brought a box of Guillow's Jetstreams. I brought one of my Double Trouble prototypes but discovered that I had left the front end back on the bench and ended up flying a Jetstream. 

Every once and a while you get a Jetstream that won't climb. This is a bit of a problem in a contest that requires ROG (ROT?) takeoffs.  I ended up extending the wing slot all the way to the prop hanger to get it to climb.  The next flight it flew straight to the trees and treed itself 20 feet up on the back side of a tree.  I got Bill Watson's modified kite pole, which acted like it was a prop from a Buster Keaton movie, and retrieved the model.  My last flight, predicted for 20 seconds, flew 31 seconds and bounced off a tree on the other side of the park...FOGETTABOUTIT!  There is always next year!

Dave Gee, the CD for the contest was feeling a bit poorly and had to leave in the middle of the contest.  Kurt Young took over as timer and CD

The results were:

Flier                                         Model              Seconds off predicted     Distance from pole

1. Barry Dougherty                      Zipper                 .2                            10' 11"
2. Bill Watson                             Own Design          .2                            16'
3. Jim Leuken                             Own Design         1.2                            50'+
4. Don Butman                            Peck ROG            4.0                           12' 10"
5. Kurt Young                             Jetstream            4.0                           50'+
6. Howard Littman                       Jetstream          11.6                           50'+
7. Stan Christopher                      Minnow              N/A                           50'+
8. Marylin Commer                       Jetstream            N/A                          N/A

The next contest is Dime Scale (Joe Whiting's 9 Cent scale rules) on July 28.  If you have a Dime Scale model and can make it that Wednesday morning, come on out!

I was out of the country for the A-6 contest on June 26 so I can't give you a description of how it went but I was given the results and a few photos.

The results:

1. Bill Watson            272   seconds
2. Jim Leuken            182.5
3. Pete Basone          179.8
4. Don Butman           148.3
5. Bud Matthews        N/A

The photos are the finishers, Bill Watson, Jim Leuken, Kurt and Barry who were timing, and Will Woods.  I don't know how Will didn't end up finishing.

The next contest was the outdoor Predicted Time/ Spot Landing contest on July 17.

The Legal Eagle contest happened on Wednesday, May 29.  There was a very good turnout for the meeting but only six members brought models for the contest.  Bill Watson, once again, proved what can be done with a light, carefully trimmed model by winning , but it wasn’t a runaway with Paul Avery coming in a close second.  Joe Whiting had an interesting design that had some structural issues but after repairs it turned in a good performance for third place.  Don Butman finished  fourth with a usual competent performance but had trouble breaking a minute.  Howard Littman brought a development of his last Legal Eagle design but he finished and trimmed it at the contest and was only able to get three flights of around 40 seconds in before the end.  Don Smith finished sixth.

Results:  (Total of best 3 flights out of 6)

1.      Bill Watson                  335.9  seconds
2.      Paul Avery                  320.2  (5 total flights)
3.      Joe Whiting                  203.2  (4 total flights)
4.      Don Butman                  175.5 
5.      Howard Littman            117.7  (3 total flights)
6.      Don Smith                    65.2  (4 total flights)

The next contest is A-6 on June 26.

The O.F.F.C. Cat Glider contest happened, as scheduled, on Wednesday, April 24.  Although several members brought gliders some were deemed not working that day and were not flown.  The contest started with 5 contestants.  One of them, Charlotte, is an eleven year old girl who was brought to the meeting by her grandfather.  (Yes, our contests are open to anyone.)

The rules were any glider, any size or materials, with rubber limited to a six inch loop and if a catapult stick is used it is limited to six inches in length.  The contestants had three sets of three flights (nine flights total) with the best single flight counted.  Cat gliders, being somewhat cantankerous if not launched just right provided an interesting, if not entertaining, variety of flights with one flight soaring gracefully near the ceiling and gliding majestically and the very next flight being shortened by slamming into the ceiling or the wall.  Charlotte did quite well.  She was coached by her grandfather but did all the flying herself.

The results were:
1.   Bill Watson         29.8 seconds
2.   Jim Leuken         22.9
3   Charlotte Acosta      17.9
4.   Don Smith         16.2
5.   Bud Matthews      13.7

CD           Howard Littman
Timers      Howard Littman, Will Woods


The next contest is Legal Eagle on May 29th.  Bud Matthews is the CD.

Wednesday, March 27, 2019, the scheduled March O.F.F.C. contest, Build On Site Delta Darts was held.  Everyone coming to the meeting was given their choice of Delta Dart materials, skins printed with various national insignia, sticks, motor sticks, glue sticks, pins, prop assemblies, CA and kicker, and rubber all supplied courtesy of the CD, Dave Gee.  The meeting was spent building the models (with very few expletives) and at the end of the meeting we went out into the gym to fly.  The contest was the best two of unlimited attempts and an end of contest mass launch.

To everyone’s surprise, since the motor sticks were, apparently, too short, they all seemed to fly well!   Most of the flights were in the 30 second range. There were some flights that were dramatic with the plane bouncing off the walls and various other obstructions but, even those had decent times.  Dave Gee had a 39 and a 41 second flight for the win.  Bill Watson had a 40 second flight, Stan Christopher had a 41 second flight and Don Butman and I had 43 second flights.  I thought I had it in the bag when I got the 43 second flight and was winding for another one when I broke the motor, and proceeded to break two more motors in a row.   Someone made the remark that I had fallen prey to competition lust.  By that time I had to put another motor in for the end of contest mass launch.

The end of contest mass launch was a riot with two models being flown right and the rest left, but amazingly no collisions!  There was a video of this but it hasn't been posted yet.  Bill Watson's Delta Dart was the last one up so he won the mass launch.

The results were:
            (Total of best two flights)
1.   Dave Gee                80 seconds
2.   Don Butman            79
3.   Bill Watson              77 (Winner of end of contest Mass Launch)
4 .  Howard Littman       77 (tie broken by time of next best flight)
5.   Stan Christopher      50
6.   Barry Daugherty      32
7.   Pete Basone            31
8.   Don Martin              22
9.   Don Smith               15

There were a couple of others that were broken test flying.  The results might have been quite different if some of the members test flying had called for a time.
