2011 NFFS Symposium Patron Program

Thanks to a schedule change and the cooperation of The Printer, we are able to extend the July 1 deadline for receiving Patron contributions for the 2011 NFFS Symposium. The letter as sent to all NFFS members last month is shown below. This is the only guaranteed way to get a copy of this year’s edition.

2011 NFFS Symposium Patron Program

EXTENDED DEADLINE JULY 15, 2011

I just returned from a two week adventure to Argentina as a supporter of the US FAI Team. What a tremendous experience to be able to interact with the best of the best from around the world at the peak of their game! I brought home a treasure chest of ideas to try to elevate my game to the next level. Have you ever wondered what it would take to do the same? The theme articles of the 2011 NFFS Symposium are designed to help you do just that. This year’s Editor, Dave Lacey has collected a series of contributions that focus on tips and techniques designed to help every modeler improve his or her performance even if your only interest is to have fun! The cutting edge technological input will still be included and of course, what would the Sympo be without the annual awards for Model of the Year and inductees into the NFFS Hall of Fame? Check out some of these feature articles:

* 20 Tips on Free Flight Modeling from Bob Stalick

* Bob Hanford will tell us how to trim Gas Models

* Tom Ioerger has the latest scoop on covering materials

* Discuss Hand Launch and Catapult Glider insight from Gene Ulm

* Low Drag Airfoils (LDA’s) are a hot topic on the world agenda right now and Brian Eggleston takes a look at the subject in the context of F1C

* Stew Meyers explains electric power applied to FAC events

* Annual Sympo contributor Peter King examines Hand Gliding

* Editor David Lacey adds “Energy Management and Free Flight Models”

* For aspiring designers, we’ll have Jim O’Reilly balance “CG vs. Tail Volume” and Jon Champion compare “Flight Time vs. Aspect ratio and Planform”

* F1A 3D Analysis is provided by Claudio Bognalo

* For the indoor Enthusiast “Capacitor Indoor Models and the Science Olympiad”

For a minimum contribution of $54….same as last year…. ($61 Canada & Mexico, $63 foreign), you will receive a copy of this year’s Symposium via Priority Mail directly from The Printer as soon as the ink dries. Any amount over $25 is tax deductible.

The deadline to take advantage of this opportunity and to be included in the Patron’s List is July 1, 2011.

SPECIAL NOTICE: DEADLINE EXTENDED TO JULY 15, 2011

This is the only guaranteed way for you to get a copy of this year’s Sympo. The days of the large over printing when you could get a copy a few years down the road are over. The last time I checked with Bob Stalick of NFFS Publications, he had exactly one copy of the 2010 Sympo in stock and I’m sure by now, it is long gone. SO DON’T PUT THIS OFF! Please complete the form at the bottom of this letter, place it in the enclosed envelope and MAIL IT TODAY! Checks and Money Orders should be made out to “NFFS” and we accept PayPal too!

Moving onto non aeromodelling physical sporting interests, entirely due to "blockers" and the lack of support for FF locally.

FFQ - #40

It has been nearly ten years since Free Flight Quarterly was started, and it is still going well, thanks to your support, both on its print and digital editions, and retaining at least three of its original editors. This issue has a wide cross section of topics, from vintage diesel engines to the newest in small electric free flights.
It was a sad moment when we learnt last April that one of our contributors, Laurie Barr, whose autobiography ("It happened to me") is being published in FFQ, died suddenly at age 83. The autobiography continues and the last installment  will appear in the October issue.
Many would find the article by Slobodan Midic on his low-drag airfoils  ( LDA's) of exceptional interest, given the fact that such airfoils are now revolutionizing the F1A glider category, being able to bunt higher than most and gliding as well as the best, although requiring a rather different trim. The report on the Free Flight World Championship in this issue highlights the accomplishments of the LDA-equipped gliders that won both glider contests at Embalse. The cover of this issue presents a tribute to Evgeny Verbitsky, the highly accomplished Ukrainian F1C designer, on his third victory  in a World Championship.
Two more articles on F1A themes are also included: the compact and ingenious  fuselage design of Julien and Bertrand Sion, with optimized packaging of the electronic components of a modern F1A ship, and the report by Allard van Wallene of the contest at Sezimovo Usti in the Czech Republic, just after the W/C at Embalse, a contest where "conventional" models did well.
Paul Rossiter brings to conclusion his wide ranging article on rubber testing, showing how careful testing and the right testing method can produce highly repeatably results.The article also contains an excellent collection of references on previous rubber testing methods. I am happy to add that  Paul did well in both F1B contests at W/C at Embalse.
Adrian Duncan takes the subject of the 1950's AMCO 3.5 diesels and in this first part deals with the very light and powerful (for its era) AMCO 3.5 plain bearing engine. We will cover the ball bearing variant in the October issue. Another in the series of the models of Gerry Zeigenfuse is published in this issue: a stylish A-1 glider from 1959, with some interesting design features. The article is graced by the superb plans of this great draughtsman.
Craig Limber from Calgary, Canada introduces us to the concept of miniature old-timers, approximately half-scale vintage FF designs, but  with a sophisticated electric power set-up. Garami's StratoStreak is illustrated in this article. Finally, a fast climbing P-30 from Southern Bavaria in Germany is described. Gunther Schmidtutz, the designer,  has incorporated a number of interesting construction features in this design, which can fly with 6 and 7-strand 1/8 in. motors.
As in past occasions , the cover and table of contents can be seen  in our website: www.freeflightquarterly.com/wordpress
