Getting Ready for the September 20th "International Cox PT-19 Fly It If You Got It Day"!

Finally got my little camera working, AND had a third calm evening to shoot some footage of the PT doing it's thing yesterday:

Thanks Rusty !!!

So, another PT joins the family!

STILL prepping for the PT Fly-a-Thon, and managed to snag this "Whisper Quiet" example...just like the one I learned to fly back in the late 60's !!!



Get ready for some Time Warping !!!!

Kim, nice score!  I was looking at that one, too.  But, I decided that since I have two PT-19s already, one flyer and one NIB, I would let it go to someone who needs it more than me, and save the money for something I really need.  Glad it went to someone who can appreciate it!

And, you said earlier that you put tail wheels on your PT-19s, and it may help looping.  I don't suppose you could take a look at your best looper and note the c.g. position on it?  That'd give us mere mortals a good place to balance ours for more sprightly performance.  I understand that Cox made these to just fuel 'n go, but it would have been nice for them to give us some c.g. positions along with the beginner through advanced settings on the engine thrust.  

Hmmm... Maybe we could note things like this for reference data in a sticky in the "Cox Model Planes and Helicopters" section.  Perhaps I'll weigh my production Cox models and measure their stock c.g. locations tomorrow to start a thread.

The Off On A Tangent Mark


edit:
Even though I didn't bid on the plane, I did take advantage of the pictures of the manual in the auction and downloaded copies of the pics to keep for future reference.  I love the discussion between Bob and Jack on how to start an engine.  The "Just Enough but not too much!" really got me.  5 drops in the exhaust?  I do one drop on a blocked exhaust port myself and that's plenty for me.  I think five drops would mean a couple dozen flips of the prop to clear the flooded head!




The Clear Headed Mark

Yeah, Mine Too...of course, with it being the FIRST ONE...there could be some "imprinting" going on!

Hey Mark,

My "best looper"...or perhaps I should say, "The one that scares me the least" balances right at 1 1/2" from the center/front of the wing...or just past that molding hole in the center.


It also comes in at 9.8 oz. according to my el cheapo postage scale. This is without pilots (I sent them to a better, more appreciative home!).

It also has the Tornado "pusher" prop which, as someone upstream commented, might help it stay out where it's supposed to.



I should have a decent collection of these poor crates flying by "PT Day" on the 20th. The new one will lead a pampered life for a least a little while, but WILL be flown.

Think I may try to claim an Unofficial World's Record of Cox PT-19 Loops on that day, using the PT shown here. Any of you guys that might have Guinness of FAI connections let me know !!!!

World Champion Aspirer Kim

Hey Roddie!

This was one of those cold Sundays when the ball diamond was a swamp, so we're launching our planes from the "grass" at the edge of the mud!  Nope, we didn't skip school...one of our Bus Drivers lived in the house just out of the frame.

Yeah, I wish I had more photos of those days!  

You could probably fit a small wedge tank up in the fuse to replace that plastic tank...I've got a metal Perfect tank in the Super PT, but am gonna swap it out for a plastic bottle when I come across one that looks right.

Not sure whether or not the PT would maintain inverted flight without a REALLY honking engine.  I MAY give it a shot at some point, but have already broken off the nose tab on half of my rudders, so it may not happen soon.  Thinking about it, the BIG deal would seem to be trying to get it back upright...but don't know...the mystery continues !!!

We did fly PT's with the gear left off, it made life a little easier landing on grass without it being jerked to a stop so quickly.  The biggest problem, the way I remember, was getting a good, clean launch with enough chuck-power to get it to speed without planting it!

I used to stare at the parts lists that came with these planes, planning my versions of "Up-Grades".  The results were sometimes painful, but ALWAYS educational!  I was REALLY ticked to find that adding an extra blade to a prop DID NOT make the plane fly faster !!!

Luckily, the hobby shop in Metropolis, Illinois--"Hop Johnson's Radio & TV Repair" kept a pretty full supply of parts, and I vaguely remember some kind of big cardboard display in the narrow side-room of the store that was the "hobby shop".  I always felt real "Official" plopping down lawn-mowing/paper route money for parts...in my mind, this raised me above just "buying toys"...I was now "Keeping My Operation Going"!

I've always used black carpet thread for leadouts on most of my 1/2A planes.  An aunt gave me a spool of the stuff that I'm STILL using after some 45 years.  I just tie loops in it, and use clips on the handle side to swap the lines between planes.

Yep, think the "International Cox PT-19 Fly It If You Got It Day" (trying to remember to always use Mark's Official Title) should be a hoot.  I intend to take the PT's on the road...loading them up and tracking down victims!  Figure a decent engine, with a three-bladed prop should produce a friendly flyer.

So far, I've got about five people on the list, warning them NOT to mysteriously disappear on September 20th!

So, it occurs to me that it might be cool to put together a retro field box to use on our PT-19 Day, using the same little tool box that my Uncle Wayne packed "Back in the Day".

Got me an operating Perfect Fuel Pump, the hollow carcass of a later version of our cherished 1.5 Volt "Telephone Battery', some runnable original Cox Fuel (with some cleverly disguised 24% GlowplugBoy in a second Cox can as a back-up), and an old handle wrapped with new dacron string.

Gonna solder up some "C" cells to fit inside the telephone battery, and find a Cox Glowhead clip that doesn't have banana plugs...and off we go...BACK TO THE 60'S !!!!

Wonder if there's someplace where I can get Super 8 Movie Film for my ancient "Don't-Forget-The-Lens-Cap-Or-You'll-Be-Sorry" movie camera?

Now, cue "Green River", please !!!

Don't forget your flairs and platforms. Anyway a good initiative, Kim!!! Couldn't you make an "official" drawing to mark the day?

Well. you might need to be fixed up with a 'Loaner' !!!

May have to look at that !!! Also, think there used to be an "STP" sticker on the side.... May have to make a run to the local shop to see if I can get one of those !!!

Try to swing this way on the 20th! I'm gonna be making a lap toward my uncle's house, then up 24/57, and over toward Scott AFB if Ron is still there. I'll steal some orange cones from the airport, and we can set up an "Official Circle" out back of some truck plaza !!!!
