So, the Breezy Hill Flyers' "Black Fly-Day" turned out to be

"Who is Nutty Enough to Fly Their Model Airplanes in Cold, Damp Air While Everybody Else is Staying Snug and Warm in Their Homes Day"

Well, guess who!
------------------------------------------------------------
Thomas and I showed up on the hill, greeted by some definitely NON-inspirational weather. Low, gray clouds were tracking by, with a cold mist hanging in the air, but the rain was holding off, so the toys got dragged out.

Thomas brought his REALLY nice Lazy Bee, along with his big-wheeled "Kingfisher". I had my bedraggled, 25 year-old Lazy Bee and Mavic Drone.

As usual, the drone took video with no photos of it's self being taken, but also as usual, the Lazy Bee got Go Pros rubber-banded around it's airframe, with a bunch of stills pulled from the footage.

We got in several flights on each, with some photos and video going on, 'till finally packing it all in and heading home.

Still a good time and good visit. We're now looking forward to the winter swap meets, along with the New Year's Day and Frozen Finger Fun-Flys!...Continue Reading

----From another thread about installing external fuel tank for .049 power in a Sterling Minnie Mambo------------

Little Traveler was, at first, going to make fuel stops along the way on it's flight for St. Jude Children's Research Hospital, using a Cox "Dragonfly" .049, as that was about the biggest engine-mounted tank offered. When a flying buddy heard about the project, and my trying to determine suitable landing/fueling sites along the way, he said, "Wuhl Hell! Why don't you just do it non-stop?" Wuhl Hell!!! Why Not!!!???

So, Little Traveler got some internal gutting, with a 4 oz Sullivan Tank tuned on it's side and shoved into it's cramped nose space. Like you, I just HAD to have a nose block (like my original Minnie) because, I thought it needed a nose block to suit my barely negotiable nostalgic demands.

I got a "Red Scorpion" .049 from Bernie at Cox International, and made a ply spacer to move it's prop out past the nose (the nose HAD to retain it's original shape---nostalgia again), and to also get the engine away from the firewall far enough to allow some "curl" in the silicone fuel line to keep it from kinking as it looped around to the brass tube epoxied in the ply next to the engine.

When fueling, I pull the plug from the internal line and pump fuel in 'till it comes out of the external vent/overflow tube. I do have to pull Little Traveler's wing to do this, but once filled, the Minnie is good for 30 minutes...Continue Reading

So, got Rene's Medallion .049 on the stand this morning, and it's looking good.

Prop: Cox Black 5 x 3
Fuel: Sig 25%

Top end was in the mid-14k's, bottom end at about 6.5k.

Thank you again Rene!

Thanks to the extreme generosity of one of my flying buds over on the Cox Engine Forum, my currently un-throttled Carl Goldberg "Ranger 42" will be cruising next summer's S.M.A.L.L. Skys behind a vintage "barrel throttle" Medallion .049.

Medallions are sort of an "interim" engine between the good-natured reedies and high-compression Tee Dee engines, and like the Tee Dees, are beam-mounted and will only run in one direction.

The Ranger presently has a Medallion .049 that runs wide open 'till it's fuel is gone and then glides in for a landing. This engine will allow low/slow passes down the flightline, along with the option to land at will (flying bud Tony will once again be asked to step up for these as I shoot some video/photos of the moment!).

Gonna be a fun summer!
Thanks Rene !!!!!!

Parts of an article by Don McGovern from his "All Wet" column in the August 1968 issue of Flying Models.

Mr. McGovern was, and is still, one of my Model Airplane Heroes, and descriptive writings of his many seaplane adventures in the briny backwaters of New Jersey created images in my mind that exist to this day.

This is one of my favorites because of the bunch of photos included.

So, a nice morning out in the shop. Got the parts for the Skylark's second engine from Bernie yesterday, and used today's "coffee high" to assemble the Tee Dee .020.

Got in a couple good test runs...no leaks, and all the parts seem to be getting along with each other.

Now, unless I again change my mind, the engines for the Skylark are chosen, tested, and ready to boost it up through the ether!!!!!!

Back to balsa chopping!

Flying bud, Tony, had asked about the run times with the Skylark's future .020 powerplants when using the new metal combination fuel tank / engine mounts.

After running the Tee Dee .020, I decided to also run an .010 that was handy, and these are the times I got. Both engines had to do some "cobweb flushing", and as expected, they ran longer with each attempt.

I think the .010 ought to get 3 minutes if mounted on an airframe.

The tank / mounts are beautiful little works of art, available from:

Another day out in the shop: The Goldberg Jr. Skylark continues to draw attention...this time from my carving knife. Yesterday afternoon, it's nose, fuse corners, and wing leading edges were victims of my deft wielding of a long-blade Exacto. The thing is really starting to develop a personality. It's wing needs a little more trimming/sanding, and one of it's Tee Dee .020's tack-glued in place for inspiration.

Uncle Wayne's 51 year-old "Scout" control line stunter got some old-school hinge stitching to support it's ancient cloth elevator hinges. This plane is still in good, flyable shape, with a healthy Cox "Golden Bee" on it's nose.

I've managed to meet several of my Heroes in full-scale and model aviation, but many had their time and passed on before I ever knew about them. Luckily, my stacks of old model airplane magazines provide a bridge to long-gone years. and introduce me to people I couldn't have appreciated had I met them as a kid.

Stephens Calhoun Smith 3rd was a Creative Force in the 1950's and early 60's. Like several of my current cronies, he seemed to have the energy of an otter chasing fun. Besides designing and building untold numbers of model airplanes, his wildly diverse artwork appeared on the front pages of many magazines, like the December 1952 Air Trails shown below. His talents in photography ranged from individual projects to event articles that helped fill the magazines that carried his paintings on their covers.

Like most of his kind, he pursued BUNCHES of other sports, like Ice Boat Racing, and who knows what else.

My only direct contact with Cal Smith is the reduced-size copy I built of his "Blunderbus" Free Flight design. Powered by a Cox Tee Dee .010, my tiny replica has only a single servo to guide it around the sky, and was an "Everyday Flyer" back in the day.

It also received high marks from my little sheltie, Chelsea, who was allowed to chase it on it's many flights since the .010 didn't pose a serious threat to her long snoot.

So some times, the search is over almost before it begins. I barely got into the place before my eyes fell upon this beautiful, barrel throttled Medallion .09RC that looks like it just fell out of it's box.

Listed as an .049, I initially got excited about adding a throttled engine to my Goldberg Ranger, but it'll do just as nicely on my Jetco Navigator (if I ever get around to restoring it).






Then, on the same table, I spotted this!

Another of my "S.M.A.L.L. Prep" models...slated for this year's 30th Anniversary S.M.A.L.L. Fly-In this October.

Carl Goldberg's Ranger 42 was a "some day model" back in my early teens. It never happened back then, but the little foam R/C plane lurked around in my brain for a few decades, until I finally got one in reasonable condition from Ebay.

Many were flown with Cox .09's and larger engines, but I wanted to use an un-throttled Medallion .049, to give myself a slow-flying retro model, and it's happily worked out that way.

So, it will join Lil' Punkin, Little Traveler, and several others in our Arkansas Pilgrimage this Fall !!!

I've had this account for some time, but haven't made any entries, mostly from be swamped with involvement in my club and other pursuits. I've decided to post some notes, photos and videos from my Facebook, along with others as this develops.

All statements are my own, about my own experience with various miniature flying machines. I claim no expertise in any area, other than maybe at having fun...at which, I feel I'm pretty much a "Fun Ninja"...I have a blast with this stuff.

Because of the audience I anticipated on Facebook, many of these posts are geared toward new flyers or people with interest, but limited or no experience in the hobby.

I'll try to respond to comments in a reasonable amount of time, but there may be some stretches where I don't get back right away.

We'll see how all this goes...
---------------------------------------------------------------------------------------------------------------------------------

Earlier in the month, I'd posted a few photos on my Facebook page of this little "Storage Locker Rescue" I'd named Lil' Punkin.

I'd been waiting for another nice evening to get some footage of the whole plane from it's top camera (having so much fun, I forgot to do it on that day), but haven't had a chance to try it.

So...I crunched together some footage of what I had.

Lil' Punkin is a rudder-only model---it has no elevator to control pitch, so has to be carefully balanced and trimmed for a gradual climb while the engine is running, then transition to a smooth glide when the engine quits.

MANY early R/C planes were flown in this configuration before more advanced radios became cheap enough for a modeler to afford.
