At the last meeting ...

Dave Andersen asked for everyone's help as he brought up his disappointment that several of the last year’s flying events caused unnecessary date conflicts.  One month had Two Events  on the same day even though there were no other "Events in the Entire Month" ... he kvetched.  Sundays were especially unused even though the few Sunday events were well attended.  Schedule conflicts are a problem every year.  He told of three events all scheduled on the same day.  On a lark, he flew one flight at each, doing more driving than flying. L


He asked those involved in CD'ing/Scheduling Events to check the previous season’s schedule by looking up the old Scale Flyers newsletters and/or event schedule online at Annual Metro Event Page Most dates don’t change from year to year, they just shift up or down one day to reflect the year to year calendar adjustment.  To avoid a conflict, event coordinators should call the director of a potentially conflicting event and negotiate non-conflicting dates between themselves.  Dave asked that event directors inform him about event dates ASAP so that he can publish them in the SFM newsletter and on the website as early as possible for best exposure and hopefully fewer conflicting dates!

Brian Crossley discussed the Tri-Valley field  search situation.  Some farm land is being considered several miles south of Rosemount in the Farmington area.  Our dear treasurer also took in some annual dues as well as selling some very nice Scale Flyers caps (Only $5).

Joe Niedermayer started a discussion on ground tracking during takeoff.  Strut rigidity, toe-in, CG, wing loading and other factors were discussed.  The technique of rudder steering  led to a lengthy and informative group discussion about gyros in “heading mode” during takeoff led by Tim Len and Scott Russell.

Engaging the heading mode with the retract switch was one solution for both takeoff and landing.  This led to a discussion of a gyros effect on other flight regimes.  It was noted that gyro sensitivity can be optimized for only one air speed.  Modern gyros are no longer mechanical devices.  They are entirely electronic, hence lighter and more reliable.  Now legal in competition thanks to Frank Tiano  who argued that they are a safety feature within our hobby.

Phil Schwartz reported that the Owatonna field no longer has a N/S runway.  It has been plowed.  Also, there has been an unsuccessful attempt to bury the airplane-eating power lines that are off the west end of the main runway.  But the power company wants $10,000 to do so.  Bummer.

Glassing Techniques

A discussion about various techniques of laying down fiberglass cloth.    Some folks apply a primer of thinned nitrate dope or other primer before glassing.  Others thin resin with acetone or 90% alcohol (rubbing alcohol, available at drug stores - don’t use 85% or else water will be trapped in the resin, making it soft).   Thinner must evaporate before the resin sets or else the result will be weak and gummy.  Applying glass cloth with a horsehair brush wraps it around curves and holds it with static electricity.

Editor's Note: Although many of you know that David Andersen's new 1/4 Scale Mitsubishi Babs won the "Best of Show Award" at the 2010 Northern Alliance Military Fly-in.  His hard work is also featured in the 2010 Fall edition of HIGHflight magazine!  For those of you who don't receive HIGHflight, grab a copy from a friend and check out this wonderful article. The article takes a deeper look into the history of the aircraft as well as highlighting a few construction steps.  All of David's plans are available for download within our website "at No-Charge"

Congratulations David from all of your modeling students!

Dave Andersen generated an article and discussion points that has been summarized below. Nick Ziroli Sr., who's also had an impact on our hobby, while providing many of you resources for your scale projects also had some thoughts as well. Nicks designs can be found at "Nick Ziroli Plans".

Where Will "New" Giant Scale Plans Come From?

When was the last time that well known scale designer released a new design? Also, other than HIGHflight, how many giant scale construction articles have been published in the model press recently?  Even Model Aviation Magazine has a policy of no longer publishing giant scale construction articles and the others seem to focus on ARF’s!

Yet, scratch-building thrives.  This is derive from our monthly website inquiries coupled with Balsa dealers having order backloads and parts suppliers staying very busy, while the Build-Threads on forums are ubiquitous.  But we feel that unless something changes, it won’t last.

In a recent email to our editor from Nick Ziroli Sr., he was kind enough to share his thoughts to a few of our discus-sion points, Nick Sr. responses are highlighted in blue.  Thanks again Mr. Ziroli for taking time away from your UAV project to share your thoughts and opinions within the SFM Newsletter.



Has the digital age taken away your incentive to publish new aircraft designs/plans?


“I don't think it is the digital age that has affected my incentive for new plans. I've designed and built over 25 big scale models in the past 25 or so years.  This was plus my aero and industrial models I was building since 1970, and still doing so as a consultant.  Today, at 75 years old I just can't spend the time at the drawing board that I used to.  The E-bay whores don't help matters either.”


What should Scale Enthusiast who doesn’t have your drawing/design skills, while desiring something different on the flight line do?


"If a modeler has built a Giant Scale model or two they would have a feel for how it is done.  Use a plan he has built from and change the outlines and modify formers and ribs to suit.  It can and has been done.  A one off cowl can be carved from foam, glassed and foam removed".


How do you feel we could deepen the Scale interest of the Top Model Magazines and encourage them to go beyond ARF’s.


"That's difficult to say.  Unfortunately the ARF's are getting better.  There is a wide choice of designs and they are cheaper than building from scratch. The only hope is that the model flyer that assembles one may get bitten by the bug hard enough to become a model builder.   I don't know what we could to encourage model building.  Time and money is probably a problem for many these days".
