Grassy Knoll report 10-21-19 By Hugh Langhans

On October 6 we had a fun fly at the Grassy Knoll. We did not have three of any one kind of aircraft to make a contest, but we did some flying and had some fun.
I forgot my winder so I borrowed one from Don Smith for my Guillows 500 FW 190 and my racer. I should have been suspicious because the prop hook kept slipping on the propeller and the planes would not fly. Of course the problem was that the winder was opposite to the winder I normally use and I was winding the rubber backwards! I finally quit when both planes swallowed their motors and I did not have a wire hook to retrieve them. (I left that at home too!)
Jonathan Nuñez flew a Ryan low wing airplane and a Piper Cub. I think the low wing plane was a Ryanair.
Don Smith flew some high wing civil airplanes.
By the time this is published, WestFac will be history. Jim Alling will have participated with WWII and cabin airplanes, rubber powered. He has been getting three minute flights from some of his WWII planes, but there will be some formidable competition from the Scale Staffel and it is rumored there will be some fliers from back East that are quite good. I am looking forward to the results.
Scale Airplanes worth modeling: Is anyone familiar with the McDonnell XP-67 Moonbat? This was the first design of Mcdonnell and was pretty radical. The engines were new also, and never got developed enough for production. The engines were Continental XIV-1430 with turbochargers. Aeromodeller had plans and an article by Dick Howard. The plans had some flaws, but there are some new plans done on
CAD that are better. Contact me if you are interested and I will try to find out where I put them.

Pictures to follow.

Here we will post pictures and stories of meeting and events at the Grassy Knoll in Van Nuys Balboa Park in California.

I was invited to fly there last Sunday on the 28th of July by Hugh Langhans. The location was quite nice. Grassy of course with lots of trees for shade at the perimeter. I met a nice group of people with a real passion for aviation and modeling.

I saw a lot of great flights and there was everything there from scale models to EDF and chuck gliders. Some very long flight times were had by many there. These guys know there stuff.

I was able for the first time to trim fly may of my recent builds the Wanderer being my favorite. You really get bit the first time the model leaves your hands and really flies nice. A joy that keeps you coming back if not to say what’s next to build and fly?

Stay tuned this page is under construction.

8-16-19 Gary Acord’s Boomer Mark 2

Gary just send me this picture of him holding his CB Model Designs Boomer he built back in 2011. He’s inspired me as you all do with your passion for this hobby.

What a great job Gary!

Please feel free to send me pictures and your stories from our group.


Everyone had a great time today. Lots of flying and a FAC WWII mass launch contest, well five of us anyway. I of course being the the newbee I landed first and was disqualified from round two and three. I have to get brave and add more turns!

I believe the Zero placed in first. Jim’s Zero is a great flyer and flew for a very long time.

We had two Zeros, a P-51, my EKW C 3606 and Hugh’s wonderful big P-40.

I’m hoping everyone sends me an email so I can place names to their faces and planes. And the results from the contest would be nice.

I flew my Wanderer which sadly landed while I still had power. The prop is not a folding prop so it popped the nose block out and danced through the center if the fuse. This taught me a lesson that I really need to use a folding prop and why. It’s easily repaired but I’m ordering a Superior Folding prop from Volare tonight!

Tried to fly both rocket planes. 3 of the motors had low power. One dud. The other three I ran did but failed to keep the X-1 in the air. I’m going to convert the X-1 into rubber pusher power. I don’t want to destroy that beautiful model with a rocket engine, just fly it. I’ll be making the modes soon. But don’t be discouraged about the Jet-X motors. These sat along time before I could test them 3 months in fact. I have seen plenty of rocket powered planes fly well on these beta test motors.

Lastly I flew the Sky Voyager. Last flight of the day. It only had about 300 turns. I released it and Gregg Gorris and I watched it fly. It circled us several times as if on rails. It got pretty high and when it wound down the prop locked and folded. It was just beautiful. But it kept turning and getting higher. Slow but surely the rest of the club came out to watch it. It got well over 400 ft. and kept going. It got so high we couldn’t see it anymore. It’s still up there somewhere. I’ll never know.

I have seen this on YouTube, read about it, been warned about it but I guess I have now joined the ranks by having the longest and highest flight of the day.

I got home I ordered another one from Josh of J@H Aerospace. I told him what happened and he wrote back that he had been told this story many times and is working on a simple DT kit for this plane. Further tests are coming when I get the DT.

Despite all the problems it was a glorious cool day at the Knoll. The Club members are the best and it’s a pure pleasure to fly with them.

Here’s a gallery of pictures Mary took from the day. Be sure to look in the right hand lower corner of the screen and click on the full sized image. I didn’t resize these so you can zoom in really close on your plane in flight. You can also right click and save the image at full size for your own, Enjoy and thank Mary. Next month we come back with the our pro 4K video camera.

Grassy Knoll Update from Hugh Langhan 9-26-19

There is still a last chance to get in the WESTFAC contests in October. The events start on Thursday October 17 at noon and go until Sunday, October 20 at 4:00PM. It will be held at Rovey Farms in
Goodyear, AZ. I think that this event is as good as the one in Geneseo every other year. Go to the site at for more details and to register.

I think we are all interested in things that fly, the stranger the better. My wife pointed out to me the latest October 2019 issue of Scientific American has an article on Pterosaurs, the first vertebrate animals to evolve powered flight. These were not Dinosaurs, but a different animal. Some of them
were huge: wingspan of more than 30 feet and a weight of 650 pounds. It is suggested that some of these animals could fly continuously for months! Now here is a challenge: who will be the first to build a tow line glider of one of these? This is not a fantasy flier because these things existed, but
perhaps it could be pre WWI scale.

The Grassy Knoll Squadron will hold a Pearl Harbor event on December 8, 2019. This is for war planes that were at Pearl Harbor the day of the attack in 1941. You have time to get something built and tested.

I have a P-40 to be documented as one of the airplanes that were in combat that day. It is a comet 18”
model. I decided to be even more impractical than usual and am fitting it with a three bladed prop. It may be unwise, but do I ever like the look of that prop!

The Scale Staffel had their last big contest of the year in Perris on September 21 and 22. Jim Alling of the Grassy Knoll Flying Club got first place in Old Time Rubber Stick, first place in Embryo, second
place in Rubber Scale, second place in WWII Mass Launch, third place in Wwi Mass Launch and third place in Greve/Thompson Mass Launch. Congratulations to Jim!
