Happy February Team!
I have seen some of you show up with planes and drones that your wife bought you for Valentine’s Day, BRAVO! It’s nice to see you getting that kind of support for your hobby.
Last month I mentioned how nice it was to be getting some rain. This month I am going to borrow (almost) a quote from Patrick Swayze : “ It’s nice, until it’s time to not be nice…” I think we have only had 3 dry weekends since the beginning of December, and I am starting to miss the drought! While on the subject of missed weekends, we lost a few events this month because the field was muddy. For scored events we skipped the monthly wing races and electroglide. Since no one earned points it should not affect our year end tallies. We also lost our last full FPV race practice day with the field fully set up. Next month FPV counts for totals so practice as you can.
Lastly we had to give up our EMAC Starter event and Trim Clinic. We are going to schedule a make-up day for this one as I feel it is critical to get this started. Thanks again to Steve Belknap for stepping up to get this arranged and getting the right people to volunteer ( or was it voluntold? ) to discuss proper plane setup and trimming techniques, and then provide pattern demonstrations. The new date for this is Sunday, March 5th starting around 10 A.M. The field will not be closed, but I ask members not participating to be mindful of what is happening at gates 5 and 6 and give them the courtesy I have come to expect. No buzzing the expensive airplanes Skip!! Also, still on the subject of wetness ( Hush Dave G! ), the field weed growth has exploded. Thank you to Dennis Laberge for the numerous hours spent with a hoe removing encroachment from the field proper. The outlying field also has more green than I have seen in a long time. Please be careful out there as now it’s almost impossible to see the rabbit holes and rocks. Walk carefully and protect those ankles. This much growth will inevitably result in a lot of dry kindling in a couple of months. During the March meeting the board will disburse 15 – 20 fire extinguishers to new members that are maintaining a solid presence at the field. This will be the 5th year we have had this practice and it still warms my heart to see people walking out to crashes with extinguishers. Remember though, the club will provide one, but if you use it, we want you to replace it so you always have one with you.
I am sure Randy will chime in, but I want to touch a bit on safety. A couple of people received prop bites this month. Please, if you are working on your electronics on the table – and not immediately going to a gate to fly, take a few minutes and remove the prop. On that note, those of you that come with first aid kits should take a quick look and see that they are all good. I bring two, just in case.
Jim sent a blast out, but I would like to elaborate on proper LiPo battery disposal. The orange sand buckets are for either dumping sand on a burning model, or a temporary holding area for a damaged battery so you do not have a problem at your table or under your hood. When you leave you are expected to take the damaged batteries with you in either a LiPo Sack or ammo can. If you just dump 15 – 20 batteries in the bucket and leave them, there is no recourse for someone with an actual problem. The best way to dispose of old batteries is to completely discharge either by adding a load using some 12V auto bulbs - 1 bulb for 3S, 2 bulbs in series for 4, 5, and 6S, or use one of the voltage checkers ( ask Randy ) that drain your battery to zero if left for a few days. I have an old BBQ that I set them in for discharging. Once at zero, cut off the connector, strip the leads and twist them together. They are now inert and can go in the trash.
Membership is continuing at a decent rate, there are still quite a few people showing up without 2017 badges though. Please get it done, there is nothing to gain from holding out, we are year to year and membership expires in December whether you pay for it now, or thing you are being “ thrifty “ waiting until June… It is disappointing to be asked to leave without flying because you have not renewed. Remember, guest privileges are for AMA members using our site for the first time ( up to 3 visits ) and are not for use by past members.
I have been handling the hot dogs on meeting days for just over 4 years. Thanks to Dennis Benitez who will be taking over from me after this month’s meeting. Things may change a bit as we pretty much decide what we want to bring, but in its base form there will be beef hot dogs, chips, and beverages. Periodically I will bring a pot of Chili as I know how many of you like it. Thanks Dennis!!
It’s that time again to call out for people that are replacing their patio furniture to bring their old chairs down to the field. We lost some to the recent winds and have had quite a few broken ones lately.
This month's fun fly event will be the Don’t Spill the Beans between 10 and 12 on the 25th. If you have a plane that can fly stable at a moderate speed and lands softly, you have a chance to bring home CASH!!. You will place a supplied container with 20 beans on your plane, take off, fly above 100 feet, pull a loop, then land as softly as you can. He with the most beans wins a share of $150.00 worth of gift certificates from Discount Hobby Warehouse. The monthly club meeting will follow, and we will return to open flying while enjoying the hot dog lunch provided by the Board of Directors.
See you there!
Place a provided container on your plane, climb to 100 feet, do a loop and land.
Prizes awarded for the most beans left!

Always, Always be sure to pull your prop/s before testing motors in the pits. We had an incident
about 3 weeks ago that could have been much worse, but was bad enough as it was. It can happen,
and please note the picture.....this was very painful taking finger tips off. This would not have happened
if the prop had been removed. This was a 3s Power System in a foamy.
The above story brings something else to mind, Having a decent First Aide Kit is always helpful. The
bandages were supplied by Brad, The President, his kit was closer than mine.....which also means I need
to review the contents of my kit. ( hint hint )
SO, if you have a new plane, and manage to land right smack in the middle of the center circle, for 30 points
please don't go out and stand next to your plane IN THE MIDDLE OF THE RUNWAY screaming TAKE MY PICTURE
30 POINTS Whoo HOOOO........SKIP !! ;-))
This next link is what the RotorPlex looked like Saturday morning Feb 18. Most of the carpets were blown up and folded.
I would like to give a shout out to a young lady named Sarah. She came by with her mom, and was needing info
on Drones for a book report......Sarah and her mom hung aound for a couple hours, and guess what........Sarah helped Dennis
handle rearranging all the carpets at the Rotorplex!! I Thanked her, and then also sent her the video and pictures I took
with my Inspire. Dennis spent much of the morning talking with Sarah about FPV and drive systems etc.... I hope she gets an A on her report.
Dennis, Thank you for all you do every day you are at the field!!
Thank you all for paying attention, and being safe!
The "fire bucket" is there for you to put your LiPo's in that are damaged, so you can leave them unattended for a short time, to be sure there is no resulting fire.
IT IS NOT THERE FOR YOU TO DISPOSE OF YOUR OLD BATTERIES!
All you are doing is making someone else take out your trash.
Please, DON’T BE THIS GUY.
Thanks to Bob Kreutzer for sharing his latest project. With the demise of his little PT-17 this looked like a nice replacement.
"The cowling and motor mounting was a bit time consuming , but turned out pretty nice.
I hope to get the “short wing Piper” on its’ wheels and the brick installed this weekend."
The readers want to know what you are up to.
Got a new plane? Building something?
I want you ALL to know that everyone is welcome to submit anything they like for the newsletter. It can be pretty much anything club/model related you like: review your favorite plane, forward a link to a video or article, send pictures, talk about a pet interest, write an article, etc. The more input, the beter the newsletter, thanks!! Bob's article above is a great example.

[Editor’s comment - Although I have no experience with the “Bat-Safe”, I do have extensive experience with the LipoSack. The article below describes “Lipo Bags”, in bullet “1.”, as less than optimal. I am here to testify the LipoSack is quite possible the MOST optimal charging and storage solution for Li-Pos. It was created by my friend and former neighbor Mark Wood. I witnessed the development and testing and it contained the flames every time. Lots of smoke came out of the vented bag but never flames. Stay away from the knock-offs, they are not built to the same standard. The LipoSack is made from American sourced materials and assembled right here in California. The manufacturer will even replace the bag, if it is ever needed to contain a fire, FOR FREE - beat that! I charge and store all my Li-Pos in LipoSacks. I agree the “ammo box” is a terrible idea for containing a Li-Po fire, any closed and locked container will become a pressure vessel and explode.
Thanks to Rob Jahnke for submitting the following artice! This is a very important subject for our activities. We should never get complacent about Li-Po safety. -Steve]
Hello fellow club members, (feel free to forward to anyone with Lipo's)
I have been doing a lot of research about charging and storing Lipo's. My interest was especially peaked when I heard the story of a friend in the San Diego club (SEFSD) who had a Lipo fire that burned down his shop.
My research has led me to a couple of conclusions:
1. Ammo Boxes and Lipo Bags MIGHT be somewhat helpful, but more often than not, they turn into pressurized flame throwers.
2. Even if you contain the fire, the smoke damage from a Lipo fire is significant. So you need to contain or exhaust or filter the smoke.
I was doing more research this morning and found this:
It looks like a great solution at a reasonable price ($60) given the cost of a fire.
This was a Kickstarter project last year but now they are available (but on backorder) from HobbyKing. They are available directly from BAT-SAFE.com as well. I talked to the inventor (Tom Mast) this morning and he has them in stock for $60 each with free shipping until the end of the month. They just started shipping these in December.
I bought three. One to use for charging batteries and two to use for storage.
Lipo fires are rare but real, and can be devastating. To me, I look at these boxes as very cheap fire insurance.
