AMA Museum Closes

The AMA Museum has officially closed. The museum will reopen in the spring of 1993 at the AMA National Flying Site in Muncie, Indiana. Members living in the Reston, Virginia, area may want to form a caravan of vans and station wagons to transport some of the models still at Headquarters to Muncie for the Grand Opening weekend, June 13–14. The caravan will probably leave Reston on Friday, June 12. If you're interested in carrying a museum model to Muncie, call the office of Executive Director Vince Mankowski at AMA Headquarters.

The reference library at AMA Headquarters remains open.

AMA Fax Numbers

AMA now has two fax numbers: one for membership applications and the other for business inquiries.

• Membership applications: (703) 435-0798
• All other business: (703) 435-7236

Use the correct fax number to prevent a delay in processing your membership application.

Club Secretaries Take Note

Your chartered club renewal kit should have arrived by now. Enclosed with it is a postage-paid card on which you are asked to provide AMA with the latitude and longitude of your flying site(s). It's important that you return these cards to Headquarters to help AMA build a national flying-site database.

Raffle Tickets

Don't forget to enter the AMA Museum Sweepstakes announced in the April issue of Model Aviation. You could win the grand prize of a one-week stay at the AMA National Flying Site in Muncie, Indiana, and take part in the ribbon-cutting ceremonies during the Grand Opening weekend, June 13–14.

• Lots of other prizes will be awarded.
• Over the next three months (beginning in March), AMA will hold monthly drawings for valuable model and modeling merchandise. Five winning tickets will be drawn on the last business day of each month.
• Entry coupons in the April and May issues of Model Aviation must be received no later than 5:00 p.m., May 28, 1992, to be included in the grand-prize drawing.

New Underwriter and Improved Medical Insurance Benefits for AMA Members

The Academy's Accident, Death & Dismemberment (AD&D) insurance policy reimburses medical expenses incurred as a result of an injury sustained in a modeling accident. Coverage is provided after a member's own group health plan pays and is designed to pay benefits of up to $25,000. A modest deductible of $50 is applied to each accident claim; payments are made directly to medical providers.

• The program has paid a total of $265,643 over the last eight years on behalf of members.
• To file a claim: notify the Academy of your intent to file. A claim form and instructions will be mailed to your home. Call 703/435-0750 and ask for extension 272 to report an accident.
• Primary medical coverage is normally employer-sponsored, spouse-sponsored, or personal for the self-employed. Medicare and Medicaid are primary where applicable. If a member has no personal group health coverage, AMA's medical policy may be primary.
• After receipt of the primary payment, forward payment documentation and itemized bills to AMA for further processing. Mrs. Acevedo handles medical claims and is the person to contact.

Effective January 1, 1992, a new expanded policy is underwritten by Commercial Life Insurance Company. Because this change reduces the cost per member, AMA now provides additional benefits:

• Physical therapy treatment
• Prescription drug reimbursement
• Coverage for medical services incurred during hospital confinement, emergency-room treatment, and hospital outpatient treatment

This program provides significant value; consider AMA membership for family members who are not yet members so they can receive these benefits in the event of a modeling accident.

Blanche Stuart Scott, Pioneer Aviator

March is National Women's History Month. In celebration, the Glen H. Curtiss Museum of Local History (Bath, New York) and the Bath chapter of the Business and Professional Women's Association will honor Blanche Stuart Scott with a month-long photographic exhibition.

• Blanche Stuart Scott was born in Rochester, New York, in 1885.
• She was the first woman to travel across the United States by automobile (1910), which led to her being approached about flying for Glenn H. Curtiss.
• After training at the Curtiss Aviation School in Hammondsport, New York, she completed her solo flight near Keuka Lake on September 2, 1910, becoming the first woman pilot in the United States.
• She flew with many exhibition teams, including the Curtiss group, and died in Rochester on January 12, 1970, at age 84.

New Deadline Set for Competition Listings

If you want your ad to run in the Competition Calendar or Non-Flying Events Calendar, please note the new deadline: all copy must be received at AMA Headquarters by the 14th of each month. This includes both Sanctioned and Non-Flying Events Calendar listings and display ads.

PR Roundup

Geoffrey Styles, Director of Marketing

PROMOTING THE IMAGE is a full-time job for the AMA marketing department. AMA retains an outside agency—Barton-Gilnelli of Philadelphia—to boost media penetration (newspapers, radio, television). The agency's work in 1991 placed AMA stories in many publications, including The Wall Street Journal, USA Today, Air & Space Magazine, Boys' Life, and numerous local newspapers. Total circulation of publications with AMA coverage exceeded 15,821,779.

Recent successes include an article in Campus Life (aimed at university students). AMA's marketing team will continue to spread the word about model aviation. Acceptance of the sport in government and private circles has improved.

Examples of club outreach and education:

• Westminster Aero Modelers (WAM) of Maryland run a School Flight Program presenting aviation programs in area schools and collaborating with the Baltimore Area Soaring Society (BASS). Their efforts earned a Governor's Citation from Maryland Governor William Donald Schaefer (issued December 1991). Club members Herman Gross, William Hasert, John Darl, Milton Peacock, and Ed Goldman were pictured holding citation certificates.
• Ernie Johnson (Rancho Cordova Elementary, Sacramento) uses simple model airplanes to teach math, manual dexterity, and other skills to special-needs and neighborhood children. The program rewards students with kits or parts and includes a year-long tally and an "Emmy Awards" Day. Volunteer Ed Coleman assists.
• The Alabama Aerospace Education Guide (K–3) is available free from local FAA education offices. It's a 260-page guide with classroom units and a teacher resource section and is recommended for K–3 teachers and volunteers working with youth.
• Ted Hansen of Grand Island, Nebraska, reported on rehabilitation and community benefits of model building and flying; his story ran in The Grand Island Independent.

More next month!

President's Corner

Don Lowe 9020 Little Bend Rd., Altamonte Springs, FL 32714

What does AMA do for you? Rather than a long discussion, here is a letter from Tom Kroggel, Commander of the Flying Tigers R/C Club (Toledo, Ohio), describing AMA assistance:

To AMA Officers:

In reading the February issue of Model Aviation I noticed a lot of comments from members on insurance or AMA's ability to help the R/C flier. Instead of everyone throwing darts at AMA, maybe it's time to hear from a club that is 100% behind AMA and the things they can do for us. I am Commander of the Flying Tigers R/C Club in Toledo, Ohio. Our club now has 94 active members. We are proud to be part of a very active District 3.

We have been flying off a closed landfill leased from the county for the last 11 years. Just this last year, the EPA found this site to be leaking or what they call "leaching." Due to health reasons we were asked to close the flying site. We complied with the EPA in every possible way. I contacted AMA for help to find a new flying site, not for AMA to buy a site for our club but to receive information on how to acquire a new site. In a couple of weeks I was sent a box full of information from letters, books and pamphlets to a "how to" book on locating and keeping flying sites. I also asked for and received the videotape, "Partnerships." All this was at no charge to the club and its membership! I am happy to report that with all this product support and some hard work from the club we have a new flying site. We have worked out a lease with Sylvania Parks and Recreation.

Our club is always trying to promote AMA and the RC hobby to the public. We do one or two mall shows every year and once again I called AMA for the mall show package. Again I received a carton full of information for the public that helps explain to them what we do and what we stand for. This package is also free to clubs and their members.

We do two airshows a year for the public, and again AMA is very helpful with its show teams. This year the club has started a winter workshop for the kids to show them how to build and to teach them safety in modeling. We are planning to introduce this program into the school system and again AMA has a program to help us out. This program is also free to clubs and AMA members.

If your club doesn't know about these programs from AMA it is up to your officers to find out. AMA can't always be there to hold your hand, but they can provide a tremendous amount of support and guidance. It's up to us as AMA members, officers, and clubs to educate the public about our hobby. So the next time you ask, "What has AMA done for me lately?" think about this. If you used all the services AMA has to offer, you would never need to ask that question again.

Regards, Tom Kroggel, Commander, Flying Tigers R/C Club

Commentary: AMA is more than an insurance provider. Members are the Academy; officers and staff work to be responsive to members' needs and to manage resources for immediate and future programs.

Flying site program and noise: AMA is working on noise-reduction solutions. Howard Crispin (Sound Committee Chair), members of R/C World Flyers, and I conducted noise measurements and produced a "How To Do It" video demonstrating testing and model set-ups to reduce noise. This video will help clubs with noise problems or those wanting to prevent them. A symposium on sound reduction is planned in conjunction with the Muncie Grand Opening (June 13–14); the symposium will be videotaped.

Contact Geoff Styles at AMA Headquarters if you have flying site problems.

Executive VP's Report

Dave Brown AMA Executive VP 4560 Layhigh Road, Hamilton, OH 45013

This report addresses rumors and explains actions taken regarding District 10 finances.

Background:

• Over a year ago the District 10 VP overspent his budget in 1990 and continued to submit expense reports. A large part of the problem was money spent to seed a patch program intended to raise funds for District 10 flying site needs.
• IRS rules require strict control and full accountability of fundraising activities by non-profit corporations; such activities must be reported in tax filings.
• At the first EC meeting in 1991, the District 10 VP agreed to provide a complete accounting and a plan to reimburse the seed money before further funds would be available. He did not provide the accounting; reimbursements were stopped.

Letter to Regg Keyawa (District 10 VP) — March 19, 1991:

To: Regg Keyawa From: Dave Brown Subject: District 10 Expense Acct.

This letter confirms my earlier telephone conversation informing you that I have frozen any further disbursements from the District 10 accounts until a satisfactory accounting and/or reimbursement of the funds used as seed money for your District Hat and T-shirt project is made. This includes the normal VP account, the AVP account, the District meeting account, and the Frequency Coordinator account. You are also not authorized to use your AMA credit card or telephone calling card until this matter is resolved.

This action was forced by the message you sent to me in your letter to Jim Sears, stating "No need to do anything, no accounting until an appointment is made." I find that attitude to be unacceptable and irresponsible.

Summary of the financial situation:

• VP account ended 1990 with a deficit of $5,610.45 after starting 1990 with $6,035.77.
• During 1990 you spent $11,646.22 from that account, plus $2,500.00 from your District meeting account, and $815.34 of the $1,000.00 allocated for AVP support.
• Total expenditures: $14,961.56. Even offsetting with remaining AVP and Frequency Coordinator funds, the over-expenditure is $4,880.34.

You stated you had my blessing for the hats/T-shirts expenditure—but that blessing was on the basis that the expense was within your budget, not an excess. New legal awareness requires reporting such fundraising to the IRS; refusal to provide an accounting could jeopardize AMA's standing. I cannot permit that.

Possible remedies and suggestions:

• Consider an apportionment system tied to district size.
• Consider elevating the stature and use of AVPs with small budgets per AVP.
• Control VP expenses either by strict limits or by restricting reimbursable items. I favor giving VPs flexibility within a budget.

At the April 1991 EC meeting, the EC unanimously supported my action (one abstention). Despite repeated requests, District 10 VP still has not provided the required accounting.

Magazine discounts: Offers from Flying Models and Model Airplane News are available to AMA members—discounted subscriptions and bonus issues.

Philosophical note: AMA is a national association of model builders and fliers "for them, by them, and of them." It functions by input, public debate, and constructive criticism. Differences of opinion are healthy; AMA solicits a wide range of input and makes decisions in the open. Unity and diversity are strengths; separatism is discouraged.

Sound & Model Aeronautics

Howard Crispin, Jr.

Big engines, big sound levels, big problems: the growth of large-scale models and large engines raises concerns about noise levels, flight distances from the pilot position, and overflight of adjacent properties. Key points and recommendations:

• The size of the model often means the flier may not appreciate the distance covered in flight and where turns are made relative to property lines and houses.
• Measure ambient sound levels at the property line to assess impact. Quiet suburban ambient levels typically range from the low 40 dB range to the mid-50 dB range.
• Aim to keep aircraft sound as close to ambient as practical. If flying at typical distances still produces sound significantly above ambient at a neighbor's property line, consider:
• Reducing sound output (better mufflers, vibration isolation, propeller selection), or
• Altering the flight path/runway location to increase distance from neighbors.

Survey and testing:

• On February 10–12, 1992, Don Lowe and members of the R/C World Club (Orlando, FL) conducted extensive ground and flight sound checks using a one-third octave band analyzer.
• Over 100 recordings were made (ground runs and fly-pasts) in aircraft ranging from .40 engines upward. Data analysis will be published; preliminary results point toward benefits from improved mufflers, vibration isolation, and propeller selection.
• R/C World will likely need to shift flight paths (runways) about 30 feet to avoid flying over houses as development progresses.

New equipment and developments:

• Landing Products has developed larger propellers (e.g., 18–10) with a metal hub and replaceable blades in two- and three-blade styles. These appear to be quieter in flight. Landing Products: P.O. Box 938, Knights Landing, CA 95645.
• A new type of vibration isolator is offered in sizes for a wide range of engines (up to several cubic inches). The system uses neoprene sheets and metal plates to isolate the engine from the airframe and is available with different insert materials to support heavier loads. Manufactured by Art Designs, P.O. Box 2606, Page, AZ 86040.

Next issue: analysis of the R/C World data and additional solutions for quieter operation. Save your fields!
