This will be brief as I am feverishly getting aircraft ready to head to Castle Airport in Attwater, Ca. for the District 10 IMAA Fly-In......For those unfamiliar with IMAA (International Miniature Aircraft Association), we hold a once a year fly-in for any monoplane with a wingspan of at least 80" or bi-plane at 76"......This is not a scale event........Big Ugly Sticks are most welcome!.....The flying site is a former USAF base with hundreds of acres of concrete! There are no awards.....no prizes....no pressure!.......Just fly, fly, fly..............and then eat, drink, laugh and spend money......Try it sometime!

In July, the SEFSD will help promote the 60th anniversary of OMBAC ( Over-the- Line) by filling in for the Blue Angels.....(Sequestration you know).....I will be approaching some of you to formation fly on  opening day..............We'll probably need about 6 aircraft and 1 heli' to pull a banner....along with likeness of Ms. Emerson (the OMBAC beauty pageant winner)!...I think that's Otto's job.....

OK.That's enough................ back to packing....... BTW........... When you see Members of the Board at the field.....Thank them for their efforts...... and Thank You Chief Grif'........... and crew!

By Jim Bombardel,

Mark your calendar June 8, 2013 as you do not want to miss it!

Pilots Meeting at 10:00 am, bombs start dropping right after, and lunch is at noon.

'Happy hour' is directly after the last pilot gets his score.

This year we will be doing the bomb drop like we did last year. The bomb drop for points will be the same, with the and the “Minimum Drop Altitude“ marker. No one can go below the minimum drop height, so everyone is dropping from the same height, (or above) which is approx. the height of our wind sock pole. Like last year, the bomb drop hardware and bombs are provided. Everyone uses the same system for points. All you need to do is bring an airplane!

If you did not attend last year's event, it's really simple to play. All the hardware you need to play the game is provided, you simply show up with the airplane of your choice. The bomb drop hardware is simply a mounted wood dowel, about 3 inches tall. All you do is get the nut to slide off the dowel at the correct time and location. You get 3 drops for total score, and we use the same ground marker used for Electroglide. Last year we had guys dropping from virtually every type of airplane, Warbird scale, motor gliders, foamy 3D, trainers and sport planes, all using a variety of methods. Some guys looped, some rolled, some just did a short dive to bring the nuts off. About the only type of aircraft we did not see were Ducted Fans! It is very easy to participate, it was designed for everyone.

The additional event will be a “Happy Hour” where you get to show off your own drop hardware and bombs. I will place a "Sacrificial Lamb" Airplane out on the runway edge to bomb! So basically, you get an hour to show off, and entertain the crowd. You can drop anything from any airplane you have, get creative and plan on entertaining the pilots. During happy hour, if you are not dropping, then you are not flying! You have all kinds of time to create some simple way of dropping any item you want. Be creative! Water Balloons, Parachute Guys, Bomb’s , Beans, Confetti, etc. If it falls (and everything does) then you can come down and DROP IT!

Be sure to mark your calendar and plan on attending because it is always fun.

BIG Fun, and a BIG SANDWICH.

We started out with lunch provided by NeuMotors at 11:30. Flying started a little after noon with Lenny showing everyone how it’s done. Gabriel had a aileron flutter and come off his plane--some skilled help from Eric helped bring the plane in for a safe landing. With technical problems keeping Gabriel on the ground early on I loaned him a B10 with contest grade power system. His first flight with it he turned in a respectable 35 laps and on his second flight 41---if he keeps improving at that rate he will be in contention for a place on the next F5B team as a junior in 2014.

So which Brushless Combination flies the Twin Star II the best?
Not only is some of the great new stuff detailed,  so is the adventure of lesser equipment,  including some which didn’t function adequately.  Fourteen years after it started,  the Twin Star II is still the best selling of the Multiplex lineup.  Basic economics are covered,  the most expensive thing about flying a Twin Star II is getting to a place to fly.  One very consistent result of testing is;  That you get what you pay for.

This account is based on six different brushless motor(s),  three voltages of Lithium Polymer (3,  4 and 5S LiPo) batteries in various quality levels,  eight prop sizes,  four different types of motor controller(s) and two quality levels of servos,  plus simple and computer radios.  All together several hundred flights on several airframes,  to reach conclusions.  This articles is largely the basics,  which is what the rest of them leave out!

As for anybody can fly a Twin Star II,  watch what an experienced RC pilot can do with one and be wowed.  The recommended control surfaces throws and modern brushless motors are enough to slew a Twin Star II Brushless around so hard the propellers cavitate.  But then that couple of grams of fiberglass at the control horns and a third of the length of the ailerons of my personal Twin Star IIs means they get the full throw instead of flexing at the attachment to the foam.  It’s something that won’t show on a You Tube video,  except as performance.

This is Part III,  where we start with Multiplexes third brushless setup (available in Germany already) and go on from there.  To get standard motors to fit the motor mounts have to be clearenced.
Part II went over current equipment.
Part I covered the original Elapor configuration and how to improve the weaknesses,  which are omitted in a vast majority of published material.

May 15 SEFSD meeting

Meeting called to order at 7:08PM by M Neale

Approved minutes from previous month.

Jim B reported that High Tech High wants to have a presentation next Thursday the 24th about radio systems. ( Jim--check this--the 24th is a Friday)

Paul talked about some proposals regarding PayPal and how it would work with the web site. There is some concerns regarding the safety waver and if we need to have a annual updated waver. Also discussed how to handle Park Pilots identification. Further evulation will be done in the next few months to see if it easy to administer.

Automomous flight activity discussion by Jim B
Jim presented a proposed testing program. Showed some autopilot hardware from 3DR. Discussed issues related to open source software. MNeale suggested that the hardware and software need to be closely controlled. Jim provided a series of suggested events to conduct during the flight tests. Discussion followed with members discussing their views on what tests should be performed. Jim will provide the BOD with a final draft of the proposed tests by e-mail to the board members. After some discussion it was agreed that the proposed tests would not be conducted at the SEFSD field. Jim proposed a field near Brown field that is known as "area 51" to conduct the tests. TimA moved that JimB will come up with a set  of possible test dates so interested BOD members could attend. Motion approved.

Our very own Jack Hix was able to drive his car home a few weeks ago after his LipoSack prevented a fire in his trunk.  The sack was in the trunk with the lipo inside while charging.  Several folks noticed smoke from Jack's car and alerted him.  But that was it, just smoke and a small scorch spot on the carpet.  Happy ending.

This month there are 4 new picture galleries for you:

Here Scott demonstrates what happens when you try to pull a quadcopter from where it was told to stay in relation to the GPS satellites.

Thank Cheif next time you see him for taking care of our field.

SEFSD hosted and taught a pack of Scouts how to fly.

Indoor flying in April was more interesting with Mike Morgan's hovering cat and flying in total darkness.

The successor to the Concorde.....flying at Mach 3.6
Twice as fast as Concorde: The SonicStar jet will be twice as fast as Concorde with a top speed of Mach 3.6.
Plans for 20-seat craft were unveiled at Paris Air Show.
HyperMach claims its SonicStar aircraft will be so quick that travelling from London to New York will take just TWO HOURS.
A trip from New York to Sydney, meanwhile, will be cut by a staggering 75 per cent - from 20 hours on a commercial airliner to just five hours.
A jet that can fly from London to Sydney in three and a half hours could rob Concorde of its title as the
fastest-ever passenger plane.
Plans have been unveiled for the HyperMach SonicStar, a business jet which will be capable of a top speed
of 2,664 mph twice as fast as Concorde.
It will fly at 62,000 ft, allowing passengers to see the curvature of the earth.
HypeMach chief executive Richard Lugg wants the plane in the skies within ten years (!) and has already
secured funding from the Department of Trade and Industry, which has agreed to support the company in Britain .

"Hi everyone:  This is a report on the 2nd Public Workshop for the Tustin Regional Park (often referred to as the Tustin Blimp Hangar).
 
First, I want to thank the over 80 enthusiasts that showed up for the first workshop on April 15.  We made a tremendous impact on the planning group.  Thanks for your inputs to them.
 
The 2nd workshop was held on 22 May, with the presentation of the initial plans for the new park.  Because of your comments, model aircraft was included in 5 different places in their presentation.  This is good, but we now want to reinforce and detail our desires.  Eight HSS members attended the second workshop, and made inputs at that time.  However we now have a great opportunity to really bring in our message.
 
The park planners had many pages of detail on their initial plans.  This 50 page document is on the OC Parks website, www.ocparks.com <http://www.ocparks.com>  and is attached here.  You now have the opportunity to review this document at your leisure, and submit your own ideas.
 
Here is what we need you to do.  After reviewing the attached document, respond with your own E-mail to This email address is being protected from spambots. You need JavaScript enabled to view it. .  Tell them that you like the park plan, and include some complementary comments.  Next, re-affirm that you support use of the hangar for indoor model aircraft, and also outdoor model flying.  Finally, include your own suggestions.  While the outdoor model flying was not our primary goal, it turns out they received requests for outdoor control line flying, outdoor R/C gliders and electric planes, and free flight model aircraft, and have shown it included in their plan.  While a specific location was not shown, we saw notes suggesting that the south event space made up of the  “South Plaza” and “Hangar Meadow” were being considered (Pages 29 and 40).  This is a very nice concrete area for control line and electric RC runway.  Immediately adjacent (the meadow) is all grass and flying could extend out over what they call “Linear Park” (a future development).  A great place for sailplanes!  Suggest that only a limited number of trees be placed in this area.
 
Be positive, be constructive, and most of all be heard.  This can work, as we see a very supportive attitude in all the planners.
