So, there I was, MINDING my own business, when one of those vagabond visions of days long-gone slides through my tired brain.

In the mid-1970's, a couple years before getting my first reliable radio control system, we were still cranking out a fair number of control line model airplanes. Sunday flydays weren't what they'd been just a few years earlier, with girls and motorcycles having taken the lead interest, but we still managed to get some flying done.

Midwest Model Co. had released several profile control line model kits featuring (as I remember): a P-51 Mustang, P-63 Kingcobra, BF-109, and my AD-1 Skyraider. All were scaled to about the same physical size, with the intent of clubs and individual flyers staging aerial combat matches.

I sorta wanted the Kingcobra, but the Skyraider was sitting on a shelf in the hobby store, so that was it. My budget was WAY too tight to risk a plane like this to combat flying, though I think I may have flown it in the same circle with Kevin's Midwest P-51 a few times.

I built it on an overturned dresser drawer in my tiny apartment on North Park Street in Cape. So if you happen to purchase some antique furniture, and find glue blobs, pencil marks, and X-ACTO scrapings on the underside of a drawer, CONGRATULATIONS!'ve also purchased an antique control line building board!

The Skyraider was a large model for my well-worn .35, but still flew OK, with scale-like loops and horizontal 8's, AND, with the lower speed allowing me...Continue Reading

My Ringmaster liked my new stooge so much that it took one of it's cushions for a ride.

No issues other than I was afraid to pull any maneuvers for fear of flinging the foam tube out in the rain-soaked soybeans, and not seeing where it landed. I was NOT in a mood to go searching out there.

So, I just flew out it's 12-minute+ fuel supply---circle---after circle---after circle---think there's a spot worn smooth in the asphalt...

Finally, all the Sig 10% burned up and the Ringer glided to a landing, with it's bit of ballast rolling up behind it.

The pressure to fly finally built up to the point that my buds and I just HAD to sling some castor and turn some circles.

That's all fine and good, but this heat can make things a little dicey, and I'm at the age where all I got to do is look a little disoriented and people want to put me in a hospital.

Our solution was to crank up around 7am, and bail before lunch time...a "Sunday Morning Fun-Fly".

So, around 5:45am, I headed the van for Breezy Hill. It turned out to be a mostly Control Line day, with the exception of Billy's wing-folding A.J. Interceptor and my Mavic Drone buzzing around. We had us a big day, and scattered around 11:30.

After letting multiple calm days pass by with not a single R/C plane circling the hill, today, the Q-Tee got a work-out.

Had some fun out in the pasture before the thunderstorms rolled through.

The Q-Tee is flying well, and having no trouble packing along it's little cameras.

Got all these projects various degrees of storage ranging from "Cold", to "Warm", to "Hot" status.

So naturally, the smart and prudent thing to do is---start ANOTHER project!

Back to the past yet Scientific Model Airplane Company's "Zipper" building notes from the Cox Engine Forum:

So, Bob's one little, though enthusiastic, comment about his fondness for Walt Musciano's 1/2A "Zipper" was just enough to push me over the edge into starting one. Went to bed thinking about it...drank coffee this morning thinking about it, so what the heck...

I built the original Scientific kit back in 1969 or so, powering it with the Babe Bee from my PT-19 QZ. A couple decades ago, I got a copy of the plan sheet, along with a nice note from the Man himself, Mr. Musciano. Been talking about building it since then.

Now, in the midst of a shop totally cluttered with tapes, dope cans, and spray equipment, I've started cutting templates from the 10% enlarged copies I made from the original plan sheet. I wanted this Zipper to be a bit larger, as I remembered the original to be better suited for a healthy .020, instead of the Babe Bee that took it around the circle like a combat wing.

Anyway, we'll see how this goes along. So far, the whole "Social Distancing" thing has turned the shop and front yard into a booming model airplane flying, dope spraying, resurrection of stalled projects, and engine test-running affair.

Everybody take care and stay healthy,

Flying 1/2A Control Liner models in the front yard on a beautiful Spring Day.

The planes are two designs from Walt Musciano; a "Big Otto" and "Golden Hawk", that were kitted by Scientific Models through the 1950's and 60's. Big Otto is powered by a Cox "Black Widow" .049, and the Golden Hawk's engine is a 1950's Cox "Space Bug" .049.

The third is a "Beginner's Ringmaster", and is powered by a Cox "Golden Bee".049.

The little Ringmaster is built from free plans that are available in the files section of the Annual Worldwide Ringmaster Fly-A-Thon FB Page

Got some front yard flying time with my Hyper Viper today, though it took some prep for each flight. The plane's plastic engine mounts are deteriorating and came loose on both flights, so I'm gonna have to do some serious thinking on the best way to keep it's engine from "departing the area".

Still, got in a couple flights in some fairly smooth air (which has been a rarity lately!).

The front yard was right on the verge of becoming somewhat solid...before this latest "Gully Washer" rolled through and returned it to a near-marsh condition, so no circle-turning gonna happen out there.

Didn't feel like working on any projects, and couldn't spray paint in the liquid air, so decided it was time to turn some fuel to noise, and jam it all together on Movie Maker.

I promise that SOMETHING will actually fly at some point, and I'll video it!

Photo 1.---drawing the fuel out of my beautiful Goldberg "Shoestring" back in 1978, after cartwheeling the model across the grass.

What would really be thought of as a friendly sport model nowadays, the 1960's racer was a hand-full for me after learning to fly on Kevin's good-natured Kadet, and building a little time on my own Navigator. A painful lesson in that, just because a tali-dragger is on the ground, DOES NOT mean that it's finished flying.

The photo was also a lesson in the need to "pin" control surface hinges, as it's right aileron has pulled loose. If this happened gradually over time, it'd eventually result in a violent "re-kitting" of the plane.

But, she flew again, and had a pretty long life as my dumb thumbs got educated....Continue Reading

Sleepless and messing with my video program.
Nothing but old engines, making racket and slinging castor oil.

The Navigator and Skylark are now ready for their white base coats, but need some less blush-worthy weather before I point a paint gun at them.

The Q-Tee is ready but for a little cosmetic stuff, which I wasn't in the mood for, so the Swap Meet Rescue Veco "Brave" became my first test of the doctor's exam table paper Andrew sent me a while back (thanks again Andrew!).

The paper's fibers don't seem to be quite as strong as my original silkspan, but it held together enough for me to dip it in water and blot it on some paper towels before doping it to the Brave's wing. It looks pretty good, so now, so I'm gonna gamble a couple coats of Brodak clear to see how it works.

It's builder had covered it with silkspan that had gone brittle with age, and also had done some filling work on it's forward fuselage. I intend just to clear-coat the bare wood (with sanding between coats) 'till I get a shine, then go with some base orange, with black & white trim. That's the plan at the moment......Continue Reading

Yes...yet ANOTHER model airplane engine test.
You've been forewarned, so no whining allowed!

The spoils of last week's "Engine Sniping", this little Anderson Royal Spitfire (MAN, I love that name!) arrived yesterday, and went straight from the mail box to it's waiting test stand.

Still brushing on coats of Brodak clear dope on the Navigator, along with adapting engines to the Q-Tee's changeable firewall. While I was at it, I cut out a firewall for two Cox Tee Dee .020's I'm gonna fly on the little parasol. I'd originally called this mod "Hammerhead", 'till flying bud Tony "xplaneguy" referred to it as a "Board of Engines"...and the name stuck!

Hopefully have it ready to fly this coming weekend.

So, brushing another clear coat on one project while trying to decide whether or not to drag out the paint gun and shoot some color at the other, I split the difference and went to work on a third project (this why I 'bout never get these suckers finished).

My late Cousin Bill built this Cox/Sanwa "Q-Tee" back in the 1980's, eventually giving it to my Uncle Wayne. When Wayne gave it to me several years ago, it was in fair shape, though the wing's silkspan was very brittle, and it had some "nose rot" from all the castor oil that had been slung on it.

I finally got around to re-covering the wing, and while rebuilding it's snout, I decided to beef-up the area behind the new firewall, and modify it to take detachable "plates" of ply, that had engines pre-mounted to them. This way, I could cut a stack of ply plates, coat them with epoxy, and put any of my orphans on them without drilling multiple holes in the Q-Tee's firewall to match their mounting patterns.

My shop now has the aroma of both Brodak clear dope, and Sig 5-Minute Epoxy wafting through it.

Smells like "Model Airplane" in there!

Got the little Ohlsson and Rice .049 going this morning.

I had to use a hair dryer to heat-soak the venturi area to free the needle valve and the unseen reed valve. It's mixture setting/RPM wandered around for a while (probably as old chunks of goop were breaking loose inside), before finally settling into a fairly steady run.

It's no power house, turning a 5-3 gray at around 10-12K, but the old dog is still running strong enough to drag a 2-channel plane around the sky.
