Hello fellow flyers!
I would like to open this month’s letter with a note on how successful our Independence Day event at the field was. We had a pretty good turn-out of club members and guests. Some came early, left, then returned later for the fireworks, Some stayed all day and watched fireworks. The weather was perfect, and the winds cooperated by coming straight down the runway at less than 10 MPH! I would like to spotlight and thank 3 people that really went out of their way to make it a great event. Rich Bonnardel did an amazing job at controlling access to our site at the gate. He probably covered 8-10 miles walking back and forth to let members without keys in/out while keeping non-members out (not an easy task!). Randy Wynant and Jim Bonnardel also went out of their way to bring in 2 LARGE gas BBQ grills and lit them up for a couple of hours for anyone to use. The late afternoon raffle went well, and the winners that were not present were contacted within the following week and notified that they had won. It was a great day – I would like to thank all that participated.
In the area of field maintenance I would also like to say THANK YOU to Dennis LaBerge for weed whacking the foliage that was creeping over the entire northern border of the runway, and Chief Griffin for his constant efforts with weed killer on the runway and the pit area. Jim had planned to sweep/soak/and roll out the field this past week, but it looks as if the “MONSOON” took care of that for us. We will keep an eye on conditions as we move into August.
Even with the recent rain, the scrub area surrounding our field is getting bone dry. I have noticed quite a few of you grabbing extinguishers before walking out to impact sites (major or minor). I appreciate your vigilance.
One thing I need to mention this month: If you bring guests or children to the site, please make sure they are courteous and follow basic rules: no burning donuts in the parking area, no throwing rocks in the parking lot or pit area, and no running/riding bikes in the pit area, and please do not mess up the porta-potty.
The rangers were accommodating and put up 2 more signs by the foot path intending to warn pedestrians of low flying aircraft if they chose to cross the field at our site. Nice to have them, but it doesn’t seem to slow people down. Please don’t buzz the pedestrians or their pets with your planes/multirotors. Part of the reason we have kept our site at this prime location is the general feeling by the city that we promote goodwill through a family oriented type of hobby - and it would be a shame if we change that perception.
On the safety side of things I need to mention again the need to announce your take-offs, landings, and intentions to cross the field in a voice that carries more than 3 feet. When you announce, it is still YOUR responsibility to turn your head and verify the pattern is clear before doing these actions. There were a few close calls last weekend where a member consistently told his buddy flying with him at the same gate that he was stepping out on the field and just stepped out in front of someone that was taking off – then a few minutes later stepped out in front of a plane landing…
This month’s event is the Bomb drop on the 25th. I encourage all of you to give it a shot. It’s a fun competition and Jim has a few prizes set up those who get the most points. Following the bomb drop will be the monthly club meeting and Lunch brought in by Julie Bonnardel.
Have a great and SAFE month!

In 1965, the Canadians designed and flew a tilt-wing VTOL airplane, designated the CL-84 Dynavert. Although it was generally successful, it never became operational. It showed promise in Search and Rescue, and could carry ordnance, but advances in jet and helicopter technology eliminated the niche it filled. Vertical, transitional and forward flight were all controlled manually; computer controlled, fly-by-wire flight still being a thing of the future. In 1973, the last one was grounded.
It flies again, albeit in model form, thanks to the advances in our radio control hobby! Unique RC, a company in China, has produced an electric powered version that takes advantage of multirotor and fixed wing stabilization technology. In hover mode, the main wing and motors are tilted vertically, and produce lift. A third motor, mounted in the rear, provides pitch and yaw control by changing rpm, and twisting side to side. In the multirotor world, this is called a "3Y" configuration. Flipping the transmitter's gear switch rotates the wing to a horizontal position. The balance control board then changes to a fixed wing mode. The rear motor shuts down, ailerons and elevator become active, and the craft becomes a standard airplane. Landing reverses the shift, bringing the plane to a hover for a vertical descent.
The Dynavert runs on a 4S 2200mah battery, using a 6-channel radio system, and can fly around 4 minutes on a pack, more if you want to take a chance on running out of juice during your landing hover! How well does it fly? The fact that it flies at all is a wonder! Hover mode is like a slightly sloppy multirotor, and forward flight is very stable, thanks to the balance board. Transition is very controllable. However, the board won't allow rolls and loops. This is a fantastic period in our hobby, a real golden age. Ten years ago, you couldn't have flown a plane like this, for any amount of money. Here's a link to some video we took recently.

Attention all newcomers to our club who are flying multi-rotors, please know that using these kinds of aircraft comes with heavy responsibility, and your individual actions have an impact on the entire community. I want to discuss two ‘drone’ incidents that made the news the past week. The first is a report that flying multi rotors caused a delay for fire-fighting aircraft working during the Cajon Pass wildfire last week. We have to work as a community to resolve this serious issue immediately. I ask that you help create a good image for our organization by not flying near these kinds of events, whether they be wildfires, police activity, or other large events without authorization. I know it’s very tempting to capture these exciting moments on FPV, but in doing so, you are hampering other people’s important work that could save lives. My message goes to a large club of 380 members, but I’m sure many of you know a friend or family member who enjoys this hobby outside of the club. Please help me spread the word by encouraging them to fly safely, even if they don’t belong to our club, so that we may all continue to enjoy this hobby.
The second incident involved a young man who posted a YouTube video of a firearm attached to a multi-rotor with the ability to discharge while flying. The AMA prohibits model aircraft from “carrying pyrotechnic devices that explode or burn, or any device which propels a projectile… that creates a hazard to persons or property”. They are clearly referring to strapping a gun on your plane. Currently, as evidenced by the video that went viral, we hobbyists have the discretion and freedom to experiment with different uses for this disruptive and exciting technology. Let us keep the freedoms we have by exercising it in a responsible way. Some legislators are working hard to place onerous regulations on our hobby, so please don’t give them a reason to restrict our privilege. Please think twice before doing something that could later have a negative impact on the model aircraft community.
"Authentic live footage clip of the air assault on the Japanese mainland, just before A-Bombs on Nagasaki and Hiroshima! Absolutely fantastic footage of some the members of what I consider to be THE GREATEST GENERATION!!! Riveting, to say the least.
To think of 600 B-29s all taking off to bomb Japan at one time is beyond my imagination. We hear so much about the Atom Bomb raids on Japanese cities by B-29s that we forget these raids took place before that...... at least I do. This is video from the color film archives so is of rather poor quality....especially at full screen. The narration (audio) isn't too bad. Please notice it is the Army Air Force (corps).
This is spectacular live footage of the 3,000 round trip mile air assault upon the Japanese mainland, with several bomber wings and a host of P-51s. This is the real way to end a war. No matter what war footage you ever saw before, this is the real deal and will keep your undivided attention."
