Over on the CEF, a few of us were talking about the old Cox PT-19 trainers, and someone said, “Like the immortal Ringmaster, these little guys are EVERYWHERE across the globe!”, and thought we should have a marathon day kind of like the Ringmaster Fly-A-Thon.

So, in that vein, we’ve decided that September 30[SUP]th[/SUP] would be the first annual “International Cox PT-19 Fly It If You Got It Day”. It’s informal, and the rules are simple. If you got one, fly it. It doesn’t matter if it’s shiny and new, or a Franken-PT. Just go out and have some Cox fun. Taking pictures or video would be nice, but just telling everyone that you got to fly is definitely in the spirit of the holiday. I’ve written my Congressman to have a bill introduced to make it a national holiday, but we can start it as a grass roots movement for now.

Sounds like this could be fun, and the 30th is my B-Day

Looks like we know what you should ask for on your birthday!

My airplane would not be available on September 30th, so I opted to fly my new, made in China, Cox PT-19 earlier than scheduled. Many thanks to the members of the Skylancers that helped to get it flying Memorial Day weekend.

The spinner had to be omitted for flight as it wasn't turning true. Response was slow and the airplane flew okay - although with lots of 'up' elevator as could be seen in the pics so there wasn't much left for flaring. Only one flight so far and I suspect it's way nose heavy. Nothing but straight and level the whole time aloft...

I'm amazed at the on-line videos of Cox PT-19's looping because I remember how difficult it was to loop any of them back in the day ('70's)...

Glad you were able to fly your PT-19. If you could give me your name, location, and how many flights, I'll add you to the running total.

Mark,

I just left a message over on the CEF about figuring out how to set a 2016 date for this event - any ideas?

BrightGarden

Ok, then, how about a date for 2017?

Lou Crane

BG,. getting late in the 2017 season...

Shall we try for 2018?

Personal opinion: The Cox PT's didn't fly well then, and won't now . What price nostalgia? Sure, it brings memories, but a lot of effort and frustration as well. NOT opposed, just not enthused. (first successful flights were not on the Cox-in-a-box classic.)

I learned how to fly controline on my friends Cox PT-19. Do I remember correctly, did the whole stabilizer/elevator pivot up and down?

A visit to Ebay and I can answer my own question. It did pivot as a whole piece. There are some for sale there.

Stickslammer

A subject near and dear to my heart, since these little planes were my introduction into model powered flight. Still trying to get one on Ebay. Don`t want to shell out 300 plus shipping,though.

Tom Nied

I know, I'd like one also. Just a thought, ever consider just making one out of balsa? Outlines aren't too hard to find. A reasonable facsimile could be built?

Stickslammer

Thanks, a good idea, since I`ve got a couple old .049s laying around.

I have one upstairs with a total of 1 flight on it. Bought it for my son. I think they need 50% nitro to run well?

Tom Nied

I've had pretty good performance with SIG Champion 25. 25% Nitromethane 20% Lubricating Oils (1/2 Castor, 1/2 Klotz) http://www.sigmfg.com/IndexText/SIGCF001.html

First airplane I flew was a Cox Skymaster. Then got a PT-19 and later a Testor's P-51. Flew all of them successfully and spent many, many hours out in the street in front of my house flying them as a 10 year old kid. LOVED flying those things. I've got a PT-19 hidden in a box around here somewhere and I'll try to dig it out for the FIIYGID.

I've got some Morgan 30% helicopter fuel I added some castor to and that's what I usually use. I've flown Cox .049's on regular old Morgan Omega 15% fuel as well. They said basically any plane flying a Cox engine counts, and you can throw a quick PT-19 together from the attached plans. This year's event is Friday, Saturday and Sunday, September 22, 23 & 24th. https://www.coxengineforum.com/t7189...-it-day-thread

I knew if I looked long enough...

Tom Nied

Wow, 30%. Yeah, that should do it. Pretty sure I remember that too.

The great thing about .049's are they don't use a lot of fuel per tankful. Can like that lasts a long time.

bingo field

Yes, that can has lasted nearly 30 years..

Stickslammer

Yikes. Does`nt glow fuel get unstable and potentially explosive after a very long time? I seem to remember reading somewhere about a batch exploding.

BrightGarden

It's just alcohol. Well, ok, 25% nitromethane. However, if there is any aging it would be through exposure to air, it doesn't change state, it would just evaporate and reduce to its castor oil content.
If it isn't stored in a suitable container it might react with whatever it is it stored in.
But exploding? I don't think so.

Tom Nied

Yeah, I'd have to completely agree with BrightGarden. I'm pretty sure if you threw a bottle or can into a blazing fire it would burn, but become unstable over time and explode, it's not going to happen. Like any fuel or flammable chemical, it would need a source of ignition. One problem with old fuel is that if it was left open, it can absorb water from the air, making it even less potent. Keep your cans and bottle tightly capped and it should be ok.

Stickslammer

That`s good to know. I just got a Cox Piper Comanche in the mail with the starting kit and fuel included, dated 1996. Cap was on tight. Ah, that fragrance.

Tom Nied

Love the fragrance.
