PT-19
« on: July 24, 2009, 06:07:41 PM »
I know that of the many coxmodels that the pt-19 was one of the more succesful at flying. I was wondering If anybody ever tried building a balsa version. I would have thought that it would have performed quite well.

     Here at Black Hawk Models we had thought about it several times and even drew up several plans. The one question that has stopped us is "Why".  Performance? We have several kits that easily out perform the Cox PT-19. As a trainer? Again we produce several kits that are far better trainers. The only reason that we could find was that it is very well known, however there are still so many Cox ones available that is not much of a selling point. Now add to all of that the cost of manufacturing and the difficulty a beginner would encounter in building it...well it just is not something we would be interrested in doing.

Hi Jim,

We have a thread going on the original Cox PT-19 that some of us developed a taste for (or obsession) as kids. It is Here:  http://stunthanger.com/smf/index.php?topic=12998.0

Based on this "obsession" I have thought about building a balsa version of he plane over the last year often. (back in the hobby only recently)
Whats odd about seeing this thread now is that I started some research to start this project yesterday and purchased the wood. When I make some progress I would be happy to post the photos here.

If you start yours then I and a few others would like to see your progress!!! At the moment I am rebuilding Cox motors for the Cox PT-19s I have. Some to fly.. some for the resto shelf queen duty. I will end up with some extras that could be used for this project. I have however considered an old OK Cub, Wen Mac or Testers McCoy Beam mount 049s as I have many of these that I bought last year. The nostalgia could be fun.

Larry, Stay on your path as for your products as they have become a road map of future fun with recent a recent purchase!

True the pt -19 is a well know and recognizable airplane of history. I do like it and would consider building 1 if I could find the right size  and such. I hope you will post pictures of what you build Mark. I'm sure I am not alone in wanting to see how you do.

I understand the feelings about the PT-19. Though I never had one myself there is something that draws many to this plane for various reasons.

I think it would be cool to build even a profile model based on the outer dimensions of the Cox bird. The draw may be limited sure but there are some who would jump at the opportunity to replicate a scratch built model. If it were me I would take one of the old crates and measure out the wingspan and use the wing itself to draw an outline onto the paper. Same thing with the fuse and stab. That would be a start. So long as you can keep the weight under the original (anyone know what one weighs with engine?) it should fly OK. The CG of the original needs to be obtained and documented as well.
 Would it be a great trainer? Maybe not great but it would do.
 Would it remind one of the Original? probably! 
 Would there be better trainers? Certainly but that is OK too.
 Would it fly better than the original? I can't see why not so long as the weight were kept low.

Just some thoughts...

Slightly off topic, I know,  but a few years ago I saw a full size restored PT-19. It was at least as cool as the Cox model.  I was told that the owner found it in a hanger at a small airport and was able to purchase and restore it.  It was fun to watch it fly.  Short take off run.  Appeared slow but agile (maybe just a good pilot).

It would seem that a "scale-ish" 1/2a PT-19, whether log, box, or profile with some concessions made for maneuverability would have to be a lot of fun for sport flying.

Didn't Blackhawk make a version of the PT-19?

It would seem that a cleverly painted Golden Hawk may fool some onlookers

     Yes. at Black Hawk Models we do make a PT-19, kit number FS 1000. The wing area is less that the Golden Hawk and there are a few other changes that make it more scale. Here is a picture that a modeler sent us.

Now I'm confused, between reply #1 and reply #6...aren't these two diametrically opposed? As in, contradicting?  What am I missing?

The COX PT-19 is larger, rubber banded together, and not something that we care to make. Our Musciano line it smaller with a hollow log fuselage and cements together. To copy the Cox plane and get it to fly would be a whole different can of worms.

I was never all that impressed with the Cox PT-19 as a trainer.  It was too big and the dihedral wing was a big minus.  While the rubber bands might get you through a few crashes, something unfixable always happened.

Just about any Scientific hollow log was a better bet for getting a beginner in the air.  The balsa could be glued back together or replaced with Sig wood. 

As long as Cox kept putting REAL Babe Bees in the plastic nasties they were a good source of engines for the logs.

I did not realize that Blackhawk had a pt-19 . I did not mean it had to be plastic and rubberbanded together. I just meant that a built up version might be nice.
Yes some of the blackhawk models are close in size I think.

We had looked at reproducing the Cox one in their size and style and turned it down but we do make a PT-19 in a standard Musciano size. It's kit number is FS 1000. Here is another picture of this model, it is modified from the kit. Note that the stats are upside down on the wings.

Yes, on the wings one point of the stars always points firward and on the fuselage always up.

Progress on the Balsa PT:

The parts are cut out. Fuse and Tail are of a Scale PT with the wing traced from a Cox Plane.

I did consider the fuse being a profile of the Cox semi scale plane as I had thought of that before and when it was suggested here that had me consider it again.

The fuse is a full profile and I am considering either an AP .061 or Tee Dee for power. I have neither though. Realistically I am after something that is  Beam Mount to the side of the PT nose.

I am not so far along that I could not switch this up. I am open to suggestions from everyone.
