Chairman’s Corner for Sep – Oct 2021

Hey SEFSD team! As the days get cooler we have been seeing more of you at the field. I have been enjoying catching up with some, and seeing the projects you have been working on while enjoying your air conditioned homes!

One thing I have noticed while watching folks returning to the flying field after a break is a rash of crashes that can be attributed to failing to pre-flight your aircraft.  Just because you have not flown it in a few months doesn’t mean it is in the exact condition as your last flight prior to putting it into “Lay up”.

 A couple of things to check every time you take a plane to the field are the condition of your clevises, and clevis keepers holding the clevis shut. Take a look at each control horn and ensure it is properly connected to the control surface, and tug firmly on each control surface to ensure the hinges are still attached as you expect. Also, give your battery connectors a good visual inspection. As you go up in voltage on bigger planes, there is an initial spark while connecting that will eventually cause failure – sometimes in flight.

When I bring planes out of a longer storage, I go through every nut and bolt to ensure it is how I expect. I check each hinge/clevis/and control horn. I look at glue joints visible in the airframe and add adhesive where necessary. I look at each servo to ensure there is no damage to the control arm and the screw is tight. Also I will carefully study the servo as it rotates for sign of gear slop or missing teeth.

Finally, I see people put planes on the runway and listen for servo noise while walking back to the gate. Then they take off without visually verifying each surface is moving as it should. Then they crash because something is reversed or not working. Your eyes are your best tool! Ensure it looks right before taking off!

Quan is looking at options for our end-of-year banquet. We missed out last year as the virus was limiting gatherings over 10 people.

As Quan is looking for banquet sites for our event, he is hearing that venues are limiting attendance to 100 people. That may change, but my advice to you is not to dawdle when we announce tickets for sale – as they will go quickly!  For newer members who have never been to a SEFSD Banquet – you get major bang for your buck! Quan is still setting up, so prices/venue/menu is still TBD, but in 2019, club members purchased a 20$ ticket for each family member attending, which got them a raffle ticket ( one per purchased meal ) for a chance at $1600 in prizes, and a sit down meal valued at around $55 per person.

We will have a few openings on the Board of Directors for 2022. If you are interested in assisting with the guidance of the club, we are looking for new blood and fresh ideas. Our next BOD meeting will be held on Oct 6th. If you would like to attend – either in person, or via ZOOM, please let a board member know.

This months club meeting at the field will be on the 25th, with the fun fly event starting at 10am and the meeting to follow around 12pm.  This months event is a club favorite – Bomb Drop. Compete for your chance at $150 dollars’ worth of gift certificates to Discount Hobby Warehouse – and Bragging rights!  One year, Eric and I were less than one inch from the center of the circle. We are all rusty now, let’s see how you do!

Fly safe,

Brad.

President’s Corner for Sep – Oct 2021

Hello members, we had a great summer of fun flies for 2021!  To continue the fun for 2021, get ready for “Bomb Drop”.   We continue to have great turnouts with Flyers, planes in hand and ready to fly and it’s good to see you all.  Our last event was “Altitude Quest”!  We had 22 members join the fun.

Altitude Quest. Object of this event was to see who could come closes to the altitude, that they choose with the Altitude Quest Spin Box.  Each member had a chance to push the button on the Altitude Quest Spin Box. Chooses were: 100, 125,150, 175, 150 x2 and 200 x2.  The x2 was not to your favor.  If you were off by 8 feet, it became 16 feet. A few of us got the x2, Jim R choose 150, his actual was 361 which became + 422 feet.  Bob B, choose 150 and he reached 122 – 56.  Then came Frederich, he chose 150 and he reached 133 feet, that came to -34 which was good for 4th place.  I chose 200, I was off by -240 feet…

It was fun to watch fliers reach an altitude in which they think they reach the altitude they chose.  The altitude was never called out, it was a secret.  So, guys were just flying.  It was a delight to see.  Thong Le chose 100 feet he reached 62 feet, short by -38 feet, good for 5th Place.  As mentioned before, Frederich came in 4th.  Daric chose 200 feet and he reached an altitude of 172 feet and was off by -28 feet, good for 3rd place.  Jon V, chose 150 and he reached 131 feet, that was off by -19 feet, good for 2nd place.

The club’s been open for some time now and we had a lot member come out.  There was a time I was not showing up and most of it was due to my Fairchild flipping over all the time and the repairs were getting to me, so I took some time off.  I believe I was gone for a few weeks.  However, this younger gentleman comes out during that time, but once I got back, he does not show up until Altitude Quest Day, he and his mom show up!  And to my surprise how grown-up Neil Zhu has changed.  He is now taller than his mom……. Neil chose 100 feet, takes off, shoots straight up, he calls it and lands.  When Denise showed me the altitude, I knew who was going to win this event.  Young Neil reached 99 feet, yes that’s off by -1…Congratulation to Neil for putting us all in our place!!!!    

We’ll try not to talk about how your president did not have your prizes available at the time of our event.  Nice copy of an award was given out.   But even when the actual gift certificates were available, there was still a mix-up.  I had given Thong Le, 5th place winner 3rd place prize and to Deric I gave, I mean Brad gave him 5th place certificate.  That was all my bad for not remembering or bring the list of winners with me.  So, beside the Hot Dog in which I own him, he will receive the complete amount he won. 

At the time I am writing this I am also packing for Hawaii.  I won’t see all of you till our monthly meeting and fun fly at the end of this month.  Enjoy flying and see you all at the Clubs Monthly Meeting!

Aloha!

Jovi

BECs Explained

By Mark Davis

There is much discussion on RC hobby bulletin boards about BEC’s.   It is popular to remove stock BECs and replace them.   Is this necessary?  Is it helpful?   Can I hook up two and have redundancy?  When do I need to disconnect the red wire from the ESC?   Well, it depends on the situation.   This article is to give a high-level model of the two main kinds of BECs, so you can understand the considerations that might apply to your situation.

What is a BEC? 

One option is to run your receiver directly from an auxiliary battery, as in Figure 1.  The other option is to steal a little power from the high voltage batteries that run your motor, and use that to run the receiver instead, as in Figure 2.   Since the motor typically uses a high voltage, this requires a voltage regulator, to regulate the high voltage down to a lower voltage that doesn’t blow up your receiver and servos.  Such a regulator is called a “Battery Eliminator Circuit” or BEC, because it “eliminates” the need for a receiver battery.  The term “BEC” is used only in RC.  To the rest of the world, it is simply called a “voltage regulator.”

 

 

 

Types of BECs

There are two main types of regulators:  Switching and linear (sometimes called “LDO”).

T28 Race Report for September 2021

See the racing pics.

See crash video here:  https://www.youtube.com/watch?v=E-9CFgHBTMs

We had another fun knock down drag out series of T28 races on Saturday 9/11. Prior to the start of racing at 10am we had a very nice flyby with Larry Kosta flying his Piper Cub towing an American flag as remembrance of 9/11.

We had a good turnout with most of the regulars in attendance. We followed the regular format with the preliminary rounds being 5 laps followed by the finals with 10 laps. It worth noting that the overall quality of flying for the T28 races is improving with this set of preliminary races having very few cuts and accidents.

The Bronze and Silver class results came in as follows:

1st) Daric Knight
2nd) Mark Davis
3rd) Ty Thompson

1st) Steve Manganelli
2nd) Bob Stinson
3rd) Alfred Ramirez

Things got a bit more aggressive with the Gold Cup heat races with more cuts and yours truly trying to shorten the course by flying through the west end pylon! The winner it turns out was the one who stayed out of trouble —no cuts or pylon clipping!

1st) Quan Nguyen( zero cuts)
2nd) Alex Sutton (second most cuts)
3rd) Brad Bender( had the most cuts)
4th) Steve Neu( got pole position)

For those getting a new T28 ready to race and are looking for the APC prop adapters see me and I will give you one–I had a batch machined. They are is no cost for these. Also for those new to our racing series I encourage you to look at the SEFSD web site and read the various articles from the last year and a half—there you will find some useful tips for racing and setting up your plane.

Our next race is set for October 9th at 10am. I understand that a new shipment of FMS 800mm T28s should be arriving soon—so for those who have been looking, the drought should be ending soon!

Last thing—if you don’t have a pilot number yet please email me with your request—FYI most of the numbers below 20 have been taken already! The number you pick should be < 99.

“Here is the H1 Unlimited Video, none of which is mine….Just the last Race – If you watch, there is a costly MISTAKE at the start.

T-28 Racing……T-BOAT Racing both have a “Flying Start”…….. DON’T CROSS the line early!!!  And Lots of sound…just not the V12 open class sounds…..”

Electroglide Report for September 2021

 The Electroglide went pretty well this past Saturday.   At the start, we were dealing with partly cloudy skies with 7 mph winds from the North West.  Eight pilots were on hand with five Radians, two Conscendos and one Easy Star.

 First Launch was briefly delayed due to my mistake with the speaker system. Quickly fixed however and we started the contest. The longest flight for that round was flown by me for 3:32 minutes. Scott Vance had a flight lasting 3:12 and Alex Sutton had the third longest flight 2:53 minutes, picking up a bonus landing of 20-points as well. I’ll point out here that Alex was the only one to hit the target circles on that first launch. The rest of us were down field or off field due to the winds.

 Second launch was again into poor conditions with the only lift being wind generated. Flight times were the short side. Again, I had the longest flight at 3:39 minutes with a 20-point landing. Scott was second with a flight time of 3:26 minutes and a 10-point landing. Deric Knight came in third at 2:59 and hit a 10-point landing. Bob Stinson also figured out the windy conditions and picked up a 10-point landing.

 Third launch had Scott flying the longest at 3:23 minutes. Dennis LaBerge came in second at 2:50 and I was third at 2:49 with a 30-point landing. Bob Stinson also picked up a 30-point landing.

 Fourth and final launch had almost all of us flying less the three minutes except for Deric Knight, who found the lift far to the West. With a flight time of 8:00 minutes and a 10-point landing, Deric showed us how to fly a glider. Scott was second with a flight time of 2:50 and a 30-point landing and I was third at 2:40 minutes. Alex Sutton picked up a 30-point landing and Bob Stinson got a 20-point landing.

 It was a tricky flying day but it was impressive to see so many pilots adapt to the windy conditions and land in the target circles. Congrats to all of you!

 Thanks to Frank Sutton for the event pictures.

Next and final Electroglide contest for the year will be on October 16th.  There will be a club sponsored raffle for all of this year’s Electroglide Pilots after the final launch and recovery.

See you then,

Treasurer’s Report for September 2021

We had 329 members as of September, and ample funds in the bank. The club has authorized $1,000 to purchase Dust Down for dust control whenever it comes back in stock. We are cautiously planning out the holiday banquet, knowing that public health orders may change. Tentatively, we hope to host the event on January 15th, 2022. We are finalizing the venue, and should have that info soon. The venue may be a little bit smaller than the previous one, so when tickets are available, purchase it quickly!
