Prez Sez
by Al Campana

December 1998. For those modelers who still build, this is their time. The weather is getting chilly and there are less flyers on the flight line.
It is also a time to reflect on our past year. Last February we boarded a bus for our annual excursion to White Plains, N.Y. for the WRAM Show. We held our first Fun-Fly of the year in June and our second in September. In between we had several outdoor meetings with interesting speakers and great show-and-tell models. In October a busload of members traveled to Silver Hill, Md. for a guided tour of the Smithsonian Air & Space Facility. And in November we held our Annual Auction which was attended by approximately 175 people. During the year at our field in Valley Forge there had to be thousands of flights made but only one reportable accident. Our Noise Abatement Program went along very well with only one aircraft failing the test. All in all, I would say that it was a very good year for flying and hanging out with your flightline buddies.
December also brings elections for club officers. On December 15, the Board of Governors will meet to discuss club matters and elect the 1999 officers. I have decided not to seek a second year as President. Being President and Newsletter Editor takes a great deal of time and I would like to get back to building models again. The cooperation I have received from the officers, BOG members, and club members, has been extremely gratifying. Running the club is not a one man show. There are many members involved, all voluntarily doing the things necessary to keep the club active and going forward.
I have really enjoyed my role as President but I feel it is time for someone else to take the reins and provide the leadership for 1999. I will continue as Editor for another year or until someone else comes forward to take it over.
A few weeks ago, long-time club member Charlie Swope had his 8th, repeat 8th mid-air collision. Just to refresh Charlie's memory, he and I had a collision on the runway two years ago. I had just landed and was taxiing back to the flightline and Charlie landed and ran into my plane. So Charlie now holds the Blue Max with 8 Stars and 1 Runway Cluster. One more mid-air Charlie, and you go back into training with Harry!
Our November Auction, held at the Lockheed Martin Facility, was a big success. Thousands of dollars of used equipment, models, engines, etc. traded hands and our food and snack concession sold out of most items. In order to make the Auction successful, many club members volunteered their time. These workers included: Jim Myers (who obtained the auction site), Ed Snead, Warren Barrick, George Sprenkle, Joe Pasquini, Sam Andreas, Jim Campana, Jeff Troy, Joe Weizer, Carl Sutton, Rudy Forst, Joe Yalove, Walt Pierzchala, Paul Davis, Al Primas, Ron Gallo, Alex Patson, Dennis DiBonaventura, Tony Szczur, Sandy Shewell, and Bonnie Davis. As you can see, it took a lot of people to make the Auction work. I would like to thank all of you for your participation in this important activity. Special thanks to Jeff Troy for contributing one-half of his profits from the sale of rolls of Coverite and books, which amounted to $136.
Our next meeting will be December 8 at the Church. Unfortunately, due to a previous commitment, I will not be able to attend. Our Vice President, Ron Gallo, has agreed to chair the meeting in place of me. However, I will be at the next BOG meeting on December 15 to oversee the election of the 1999 officers.

Finally, here's a great recipe for a Holiday Fruitcake. You'll need water, sugar, four eggs, dried fruit, salt, brown sugar, lemon juice, nuts, and a bottle of whiskey.
Sample the whiskey to check for quality.
Take a large bowl. Check the whiskey again. To be sure it's the highest quality, pour one level cup and drink. Repeat. Turn on the electric mixer, beat one cup in a large fluffy bowl. Add one tsp. of sugar and beat again. Make sure the whiskey is still OK. Cry another cup. Turn off the mixer. Beat two leggs and add to the bowl and chuck in a cup of dried fruit. Mix on the tuner. If the fired druit gets stuck in the beaters, pry it loose with a drewscriver.
Sample the whiskey to check for tonsisticity. Next, sift two cups of salt. Or something. Who cares? Check the whiskey. Now sift the lemon juice and strain the nuts. Add one table. Spoon. Of sugar or something. Whatever
Grease the oven. Don't forget to beat off the turner. Throw the bowl out the window. Check the whiskey. Check the oven every 5 doneness for minutes. (Hic)

The Garber Facility
By Ernie McGauley

On Saturday, October 31, I was part of a group from the Valley Forge Signal Seekers R/C Model Airplane Club that took a bus trip to the Garber Facility in Silver Hill, Md. The trip was hosted by Joe Weizer who did an outstanding job of making transportation arrangements and providing refreshments and entertainment (airplane videos) to and from the Facility.
Thank you Joe!
Upon arrival we were divided into two groups, each having a volunteer guideperson. We were taken on a tour of several buildings which stored probably hundreds of aircraft and parts of aircraft. This Facility is not to be confused with a museum atmosphere where the displays are laid out for viewing in an attractive manner. Rather it would be comparable to a workplace-type repair facility with pieces and parts and many whole airplanes which are in various states of corrosion and decay. In a word, I felt as if I was touring an aircraft junkyard. This is the place that all of the items seen in the Air & Space Museum are restored before the Museum puts them on display. One of the buildings had restoration shops such as a machine shop, a wood-
working shop, etc. In these shops, airplanes are restored to a level where they could be flown. They will never fly again since this is considered to be "Airplane Heaven" (a final resting place).
The tour guides provided knowledgeable information about the various things that we saw. Their manner of speaking was conversational as opposed to a memorized textbook delivery which made the tour even more enjoyable.

Relics Visit Relics
By Warren Barrick

Our Saturday, October 31st visit to the Garber Facility of the National Air and Space Museum was a real blast. Joe Weizer organized the trip and 38 participants: members, wives, friends and even grandchildren had a worthwhile experience. We enjoyed hoagies, refreshments, the bus ride, and also had a group picture taken in front of the Facility.
The Garber Facility is the attic/storage space/restoration location of the Air & Space Museum. When we arrived we were divided into two groups and docents (lecturers) led each group on informative tours of several of the buildings . This writer was fortunate to be in a group which included several club members who are veterans of WW II. Thus the title "Relics Visit Relics". Bob Flick, Joe Weizer, and Bud Sherwood to name a few were just as knowledgeable and experienced as our docent. Each added much to the tour by recalling first-hand experiences at stops along the way through the facility. The nostalgia was tangible. It was a great moment for all of us who were there.
Planes shown us dated from the origins of manned flight to the present and include aircraft from former enemies as well as allies in past wars. Space capsules in various stages of restoration were also displayed. The machines and toolrooms of the restorers were equally awesome.
This was a real "trip" for an airplane junky. It would be foolish to try and list all that we saw except to say that everything you ever wanted to see and then some was there.
Our docent, by the way, was a graduate of Upper Darby High School, and a classmate of Al Campana.
Make plans to visit the Garber Facility.

Training Update
By Jim Campana

Since the winds of October continued blowing through November, there were no new soloed pilots this Fall. I decided that this would be a good time to disclose how the training program went this year.
We began the year with 22 students. This number does not include the 8 students which dropped out from the previous year. We picked up 28 new students this year. I was able to assign all but 5 students. Of these 50 students, 8 soloed. We currently have 42 people in the instruction program. This number will be difficult to carry into next year.
VFSS currently has 11 active and 7 inactive instructors (not assigned any students). The inactive instructors aid the active instructors by helping students for a day when too many students show up at one time.
What I need are a few more active instructors. I need qualified pilots with a couple of years of flying under their belts and a willingness to pass on their capabilities. I will not force you to take on 3 or 4 students. If you could come out 2 or 3 times a week and spend an hour or two teaching, I would like to talk to you. It is an incredible thrill to see a smile on a new pilot when he graduates from the training program. I want guys who can help generate that smile. Call me or email at jmcampana@erols.com.

Building With Epoxy
By Robert Caso

Most of us follow the good building practice of using epoxy in joining firewalls and landing gear mounts to fuselages. Epoxy is a natural gap filler, retains some degree of flexibility when set and certain types have high tensile strength when mixed and applied properly. An often overlooked property is it's ability to seep into and therefore bond together wood or other compatible fibers. This is generally why a slow setting epoxy has a higher tensile strength than the 5 minute stuff. The epoxy joint will be stronger the more seepage that is allowed to occur into the material prior to setting. Although it is this last feature that is the most important
it is probably the one most often overlooked attribute in determining the appropriate building situation for an epoxy based adhesive.
Now we get to the issue as to why "things are ungluable". Glues themselves bond in a mechanical way by seeping into fibers as mentioned above and then hardening. Metals generally are not fibrous and therefore don't allow for this seepage to occur. Nevertheless, one could successfully attach a piece of screening to wood with some success because of the mechcanical bond that would result. Roughing up the surface also helps but is not a guaranteed solution. The bottom line here is that without this mechanical bond, hardened epoxy by itself is rather weak. Don't believe the weakness argument? You can snap in half a 1/16 in. piece of hardened epoxy with about the same level of effort needed for a slightly thicker piece of hard balsa. When you examine two pieces of wood joined with epoxy, what you wind up with is a very basic form of composite construction, with the wood fibers mechanically locked together. In composite construction, such as a fiberglass fuselage for example, each material separately has little or no strength alone, but when combined utilize the best properties of each other to generate strength. Ever get CA on your shirt? Now you why it's so hard to remove!
OK, so how do we use epoxy to maximize strength and for what applications? If you believe the above arguments, then we should conclude that the less free standing epoxy there is in a joint, the stronger the joint will be. Assuming we're doing wood, this conclusion is valid since it is not the epoxy we want, it's the mechanical bond between the materials and among each of the material's fibers that we're after. Less is more in this case. This is another reason to clamp a joint and to use a slow set epoxy (at least 30 minute) for critical applications such as firewalls. Surface variations and voids between fibers will be taken up by the viscosity of the epoxy, creating the desired mechanical bond. Excess "pools" of epoxy add virtually no strength but a lot of weight since epoxies are relatively heavy.
Another technique that I have recently been using is mixing in some 1/16" milled fiberglass strands to slow set epoxy. This helps in two ways. First, any free standing epoxy is now laced with little fibers, creating a composite structure. Secondly, the fibers, when set up in the epoxy matrix will knit together the surface grain of the materials so that the wood is less likely to fracture along the grain when exposed to a load. This adds a tremendous amount of strength since now you have hardened glass and wood fibers everywhere when things are set up.

FCC R/C Specs - 1998

The following info was printed in Scale R/C Modeler,
September, 1998 issue.

"The FCC has informed the Radio Control Mfg. Assoc. of new policies that require all R/C transmitters which operate in the 72 to 76 MHz band meet narrow-band and other certain emission standards in order to be operated in the United States.
Operation of wide-band equipment, which does not meet such guidelines, would be a violation of FCC Rules and Regulations, and may be subject to penalty. Non-compliant equipment can no longer be serviced or updated by your manufacturer.
Pursuant to Federal Communications Commission Rules 95.623 and 95.635, as of March 1, 1998, all remote control transmitters that operate in the 72 to 76 MHz band must be maintained within a frequency tolerance of 0.002% and meet certain emissions standards.
Users who continue to operate transmitters with a frequency tolerance of 0.005% or fail to meet the emissions requirements after March 1, 1998, will be in violation of Rule(s) 95.623 and/or 95.635 and may be subject to legal liability. Transmitters that have already been narrow-banded under a FCC Class I Permissive Change within the meaning of Section 2.1001 (b) are not affected."
Signed, FCC.

What does this all mean? It seems to say that old wide-band TX's can no longer be upgraded, but TX's that already have been modified (narrow-banded) are OK.
By virtue of this law that is now in effect, it's a pretty sure bet that the AMA insurance would not cover any incident involving this illegal equipment.
