President’s Corner for May/June 2018


What a nice month to be flying RC aircraft! Just a touch of precipitation, but not enough to ruin your day and the winds were generally right down the runway. We definitely fared better than the rest of the country.

As I said last month, we haven’t had the normal growth explosion in the surrounding field area. This is both good and bad. It is easier to find aircraft components out there, but everything is already bone dry and more susceptible to fire. Please keep bringing and using your fire extinguishers to help keep our site safe. Also, with how dry the weeds are – they are more like barbed wire than anything else, try to avoid going off of the runway unless you would rather spend more time repairing damaged aircraft than flying…

A couple of neat things to talk about this month. First of is the Fourth of July event which is about 6 weeks off. For the newer members that are not aware of the benefits to our location on the fourth of July, I ask: How would you like a free lunch, a fun day  flying with your friends, a front row seat to the fireworks, and a “little known” exit strategy that will avoid most of the post fireworks traffic jam? We have all of that – and more! We traditionally have a MEMBERS ONLY – closed gate day for you, family, and friends. We will have lunch on site, there will be a grill or two for those who want to bring and cook dinner on site, the Sea World Fireworks go off around 10:00 P.M., then as you exit the site – if you go across Sea World drive at the light and turn left onto Old Sea World drive, it will take you a bit east to Friars road where you can make a quicker getaway. The lunch plan is not finalized, more on that in the June newsletter- but we are providing lunch to you and your family if they want to join you. After lunch will be a really great raffle to raise funds for our end-of-year holiday banquet. We have authorized the purchase of approximately $2500 dollars’ worth of raffle prizes this year, and I will say that Jim and I already possess 2 of the 6S receiver-ready planes included in the raffle and they are among both of our favorite planes. Tickets for this raffle will be $5.00 each, and I will say that if the people that enjoyed the banquet last year each purchase 4 tickets, that will get us half way to funding next year’s event. If you have not been attending these, we have been having a great time and I want to see you there with your spouse if possible! Larry Sarkozy has a head start on purchasing his tickets – He will not be back in our zip code until after the holiday, but already purchased his 4 tickets.  For the rest of us, ticket sales will start this Saturday, the 26th at our monthly fun fly event. You can purchase tickets from any of the board members, or as a last resort via PayPal like last year. I would rather avoid the online stuff as last year I had to write names on over a thousand tickets myself and my knuckles were sore for a month…

After just 2 weeks of locking the porta potty there has been a very noticeable change in overall cleanliness. I had just assumed some of us were slobs and others were just plain nasty. NICE Surprise! It was the general public that see our unit from the road and blow in at 50 miles per hour!! We also received permission from the vendor to camouflage the unit again to make it less visible from the street. Jim (Picasso) did the spray out and I know it really helped to keep unnecessary traffic down the last 2 weekends. The porta potty lock is keyed to match the gate, so please ensure you have your key with you. Keys can be purchased on site for $3.00 (our cost) from myself, Randy, and Dennis LaBerge.

 PLEASE, PLEASE, and in case I didn’t say it yet, Please – if you are the last member leaving the site – close and lock the gate behind you. If there are random vehicles there, knock on the window and inform them that the site is being locked. If there are empty vehicles there, lock the gate- they will figure it out. Part of our agreement with the city is that ALL people flying aircraft at our site will be insured (AMA), and will be versed and monitored for correct safety practices (SEFSD Membership with safety officer).  Randy and I stayed late a few weeks ago and were surprised at the number of people that rolled in to the runway and rotorplex area late afternoon that stated they always come late when no one else is around and the gate is open. Even though it is posted at the main gate, at every flying gate at the runway, and at the rotorplex the AMA and SEFSD membership is required – they all “Magically” didn’t know about any such requirement. Again – close the gate upon exiting.

We are approaching 330 members for 2018. Still a bit behind last year, but I am thinking that may be because some prior members still have not renewed for this year. In the last couple of weeks Jim, Randy, and I have approached quite a few people (flying) that stated they thought they had renewed ( but had not) and people that claimed they had paid for a 2 year membership. We only did that in 2015, and those expired in 2016.  Please continue to wear your badges while flying so we know you are a member. Members – please continue to ask people not wearing badges to show you their badge. If they are a prior member, Guest privileges do not apply and they need to join the club before they continue flying (they can join from their phone on the spot of their AMA is up to date) If they have never been a SEFSD member and are visiting (with AMA) we will let them fly as our guest up to 3 days before asking them to join our club. They are required to sign the guest log and a member must brief them on our safety practices and observe a flight to ensure the person is not a menace.

There were a few more close calls last month involving people either failing to call out their intentions, or calling too lightly to be heard at other gates. Please LOUDLY announce when you are crossing the field, taking off or landing, doing touch and goes, or are making low passes at the edge of the runway. Not only does bad behavior is this respect put aircraft in jeopardy, it can cause serious personal injury. It is ALWAYS ( did I say always?) the responsibility of the person stepping onto or placing an aircraft onto, or taxiing onto the runway to LOOK at planes in the air or on the runway to determine if it is safe to proceed. Last month I heard a pilot (Loudly – thank you) call landing – who then landed – to immediately destroy his plane hitting another whose pilot failed to listen, failed to look, and gunned his aircraft at full throttle from the gate. I myself, after I called landing twice (Loudly), nearly hit a member with a 30 lb. plane already on the ground and rolling out when he started crossing (unannounced, of course) from the gate immediately to my right. Luckily I was able to yank it up over his head, and once clear of him I powered up and went around. I would hate to think what that carbon prop would have done to him. Please be aware – safety is for all of us – not just the safety officer…

As we pass Memorial Day, a lot of people are setting up their back yards for the summer events and parties to come. As you look at your yard furniture from last from previous summers and you contemplate replacing things – we are always accepting donations of used chairs, and even umbrellas. Last year Ray and I each donated $100.00 to purchase 10 chairs from Home Depot, only 2 of those remain.

I know I have been long winded this month, but needed to say things, so to wrap it up:

The Good Time Race League will be kicking off their summer race series at our rotor plex area this weekend. Drone racing is a lot of fun to watch, and for those on the fence – this may be your chance to see what it is all about. I ask that all plane pilots be extra vigilant to carry our fence line out in an imaginary line towards Friars road, and not cross that line. This will keep you from flying over people at the rotor plex area.

Our monthly fun fly event is the extremely popular “Don’t spill the beans!” event which will start at 10:00 A.M. Saturday the 26th to be followed by the monthly meeting and our customary hot dog lunch for members.


Don’t Spill the Beans!

Project RC Pilot

Hello Members, 

Our friend, Steve Scott, has started a non profit based mentoring activity called Project RC Pilot. This is for low income children to have the opportunity to build and fly R/C aircraft. This is a great chance for these kids to get involved in our hobby when they would not otherwise be able to because of the cost.  So far the Project has been a success. Steve is also demonstrating Drone skills required for a job as well. Donations are needed to really get this Project moving! If you can, please help.

Electroglide Report for May 2018

By Jeff Struthers

A May Gray day it was last Saturday. Winds blowing from the south at 5 mph for the 10:00 a.m. start.

First launch had Nine pilots taking to the sky, seven Radians, one Easy Star and one open class glider. The lift was there, up high towards the north west. It took a near vertical climb out on launch to get high enough to where the lift was, only Alex Sutton, Steve Gobel and myself got lucky and found it.

Alex had the long flight at 6:40 minutes with a 10-point bonus landing. I had a 6:37 flight and Steve had a flight of 4:45 minutes with a 30-point landing.

Other bonus landing credits earned were by Fred Daugherty for 10-points. Jon Graber and Carlos Mercado both earned 20-point landings on that first round.

Second launch two minutes later found no lift. We all tried the same spot in the sky to no avail. My flight was the longest at 3:32 minutes, Alex Sutton came down at 3:20 and Steve Gobel had 2:40 minutes aloft. Strange that just two minutes after concluding that first launch, such a change in weather conditions can occur.

Extra points earned through spot landings are a way to adjust to the lack of lift and that second launch had one 30-point landing, myself. Two 20-point landings, Alex and Fred, and three 10-point landings earned by Steve, Stephen Treger and Carlos.

Third launch found a slight improvement in conditions. Fred and Rich Rogers had the longest flight time of 4 minutes, 19 seconds each. Two 20-point landings were earned by Stephen and Jon, and Alex picked up another 10-point landing.

Forth and final launch had flight times increasing a bit more. Fred had the long flight at 5:42, and Carlos a close second at 5:29. Alex came in third with a 4:55 minutes aloft. Bonus landing credits were earned by many. I earned a 30-point landing. Steve, Fred, Stephen and Carlos all earned 20-point landings, and Rich Rogers picked up a 10-point landing.

It was great to see so many pilots landing in the target circles and earning bonus points. Paying attention to sink rate, estimating wind speed before making that final turn and having the correct altitude to land where they needed to. All without a motor to help, it’s a hard thing to do. So, congrats to everyone that day for flying so well.

Winner for the day was myself at 173 total points. Second place was Steve Goebel at 163-points and third place goes to Alex Sutton at 153-points.

Thanks again to Frank Sutton for the Electroglide pictures.

Next Electroglide is set for Saturday, June 16th. First launch is 10:00 a.m.

See you there,

Safety Report for May 2018

By Tony Blackhurst

Hey pilots,

It’s been a great time to fly. The weather isn’t to hot and the sun is hiding behind clouds till about noon. Please remember that as we move into summer, days will get hotter and the sun will hurt you if you’re not prepared. Sunscreen is a great thing to have in your flight bag to protect you from the sun. And water is essential at any time while at the field and especially as we head into hotter months, dehydration is a real threat as we move into summer, so do yourself a favor and bring water and stay hydrated. And remember the most important part have fun and stay safe in the air.

Find the CG For Large Airplanes Accurately

Jerry Neuberger has a cool new toy:  The CG Wizard!  Have you ever tried to check the CG of a large airplane?  It can be a challenge.  With the CG Wizard it is easy and accurate.  The huge B-17 shown is in Frank Gagliardi’s garage.  It sits atop a large table on the CG Wizard’s three digital weight sensors, one for each wheel.  Those weights along with some careful measurements gives you the CG location.  More details of the procedure are shown below in the pictures.

Setting Up Milti-Motor Electrics

Click the pic for the article.

Note from the editor – The above article is excellent but to avoid asymmetric thrust due to one motor quitting there are a few things I do when I set up a twin:  (1) The low voltage cutoff in the ESC is there to save your Li-Po from over-discharging.  This is at the expense of your plane.  In a single engine plane you can usually glide and land after it kicks in.  On a twin you will probably see one ESC go into LVC before the other.  This will give full power to one motor and no power to the other.  If this happens on climb-out you will be astonished how fast your plane can screw into the ground.  I program the low voltage cutoffs in the ESCs so they will not cut off until the battery voltage is below 2 – 2.5V per cell.  This saves the plane at the expense of the battery.  Most of us rarely fly into the cutoff anyway.  Know your plane and do not fly too long.  (2)  The ESCs I use also have over-current protection.  The ESC will cut off if the current is too high.  Naturally, this would happen to one ESC first thereby causing asymmetric thrust and your plane will perform a “helix” maneuver into the ground.  Since it is an over-current protector it would most likely happen during climb-out.  I turn off the over-current protection on my twins’ ESCs.  If you have done your setup correctly, and tested the current at full throttle afterward, you will never need the protection anyway.  (3)  I use an RX battery or UBEC rather that depend on one of the ESCs for radio power.

Wing Cube Loading (WCL)

By Ken Meyers  (Reprinted from the June 2018 Ampeer)

This is revised, updated and added information from the CWL section “Wing Cube Loading (WCL)” in the article “One Way of Selecting a Brushless Outrunner Electric Motor for a Radio Controlled (RC or R/C) Sport Plane or Sport Scale Plane Using ANR26650M1 (A123 Systems NanophospateTM lithium ion) 2300mAh Cells”, by Ken Myers, December 2007

Wing loading is a lousy way to compare models with each other and with full-scale airplanes, because wing loading varies with the size of the plane. The problem is that we are dividing weight, a cubic-like function (weight is proportional to volume which we measure in cubic feet) by area, a squared function measured in square feet. We should be, and many modelers are, comparing planes by their wing cube loading, which is independent of size because both the numerator and the denominator are cubic.” 
Francis Reynolds, Model Builder, September 1989
(Bold font created by KM for emphasis.)

Wing Cube Loading (WCL) provides a comparative value which can be used as an indicator, or a rule of thumb, for grouping radio controlled, miniature, aircraft by similar flight characteristics and “flyability”. As Mr. Reynolds notes in his article, some people feel that it is a better “flyability” indicator than wing area loading (WAL) expressed in oz./sq.ft. of wing area. The WCL comparative value, or even WAL, has little to do with the aerodynamics needed to get the model to fly at various sizes/scales in real, un-scaleable air.

AMA Needs Your Help

Dear AMA members,

Most of you have probably read our recent letter to AMA members, requesting help to protect the Special Rule for Model Aircraft (Section 336). We are requesting our clubs’ assistance to reach as many model aircraft enthusiasts as possible and amplify our message.

Congress has begun drafting language to address Section 336.  During this process, some are asking for the repeal of Section 336 – which has allowed AMA to manage our members and fly safely and responsibly, as we have for over 80 years. Losing the Special Rule would be an enormous burden for our hobby.

There are currently two paths to fly legally in the U.S. – either under Section 336 or under the FAA’s Small UAS Rule (Part 107).  If Section 336 is repealed, everyone will have to take an in person test, pay for a remote pilot’s certificate, and fly under Part 107 rules.  Under Part 107, an individual must be at least 16 years of age to obtain the remote pilot’s certificate, so this path leaves AMA’s 50,000 youth members unable to fly.

This is a critical moment to let your elected representatives know the importance of Section 336 to education, innovation, and hobbyists. You can help by doing the following:

1.  Share AMA’s Facebook and Twitter posts to contact their legislators.

2.  Forward this email to your club member list, in case our membership records do not contain a person’s most current email address or as a reminder to those that have not yet contacted their representatives.

3.  Mention this campaign at the flying site and during your next meeting to your members that may not utilize email or social media.

Please ask everyone to click here to send a letter to your elected representatives in support of the Special Rule for Model Aircraft. In addition to sending a letter, you will also have an opportunity to call your representatives. We encourage everyone to take the time for this as well.

We need your help to demonstrate the value of the Special Rule for Model Aircraft for our community and future generations of hobbyists. We appreciate your assistance in protecting Section 336 and promoting the safe integration of model aircraft into the national airspace system.
