Default PT-19

I recently purchased a built PT-19 at a yard sale. Seller said it was built by a former room mate, who left it behind. Seller does not know R/C and knows nothing more about it. I'd like anybody's guess as to what kit or plans it was built from.

It has a 70.5 inch wingspan and is about 45 inches long. It is balsa/play construction with heat-shrink covering. Looks to be made from plans (instead of a kit), but I could be wrong. It has cables attached to the fuselage for supporting the wings, and it has metal rod bracing between the horizontal and vertical stabilizers. No electronics or engine included to help determine the age, but I would guess it's not more than 10 years old.

Any input as to kit or plans that fit this description is appreciated. Also, any recommendation as to appropriate engine size to use.

Pictures would help a lot. Also see if you can find any numbers stamped on the internal parts.

A photo might help. It doesn't sound like a PT-19. They don't have wing bracing or bracing in the horzonatal or vertical stabs.
Ihave a Jetco kit from the fifties of the PT-19 that is 1/6 scale and it has a 72 inch span. Ihave attached a photo of a full scale PT-19 Itook several weeks ago. Does it look like this?

Dash: It looks just like the photo you posted. Same color scheme, including the red stripes on the rudder, and double open cockpit with small windscreens. But it does have the wire bracing.

Look like this: Ryan ST STA. Sig made a kit back then. Maybe painted to look like a PT-19?

Could be a PT-16, which has flying wires on wing and on tail. Found this photo on internet.

Now, who made a kit or plans for a PT-16?

Here is a good infolight shot of the PT-22. I'm guessing that this is the plane you may have.. Some have wheel pants and spats for the gear which cleans them up quite a bit.

That looks to be it. Model just doesn't have all of the scale details, like the radial engine, the scale details on the landing gear and wires under the wings. Threw me off, as the model I got has the same classic blue and yellow paint scheme that I always see on the PT-19.

Thanks for the input!

That would be the SIG Ryan STA/PT-20 kit which is no longer available. Check Ebay as the kits occasionally show up there. The plans were published in Model Airplane News around the same time the kit was released. That particular model was based on an STA that was set up for airshow work.

The Fairchild PT-19 is of all wood construction that was internally braced while the Ryan STA airplanes used external wire bracing.

If i had to guess, that is a kit bashed sig AstroHog. Constant chrod wing, strip ailerons, long tail moment, all points to the Hog.

Not sure if it is a modified Astro Hog or not but I would be willing to bet money it is not a Sig Ryan STA. The Sig kit is well known for its fidelity to scale and would be easily recognized. The airplane in edbu1's picture is not readily identifyable by me as a replica of any particular type.

Interesting! The Sig Astro-Hog does have a 71 inch wingspan, just like this model. And it does have a second set of hardwood landing gear mounts further back on the underside of the wing, like for a tricycle landing gear, though the gear mounted on it is for tail-dragger. I see the Hog can be set up either way.

What are some of the other specs. on the Astro-Hog that could easily be checked, like the wing chord and the fuselage length?

Look up SIG on the net then enter the Hog or the Ryan, specs are there.

Could be neither and somebody else's PT -16 or 20 kit or bashed from about anything. I have a Pilot PT-19 partly build, so it could be one of those. I think almost every kit maker had them and almost everyone wanted to or actually built one of the Ryan trainers or ST-As

More pics of yours would really help to id it.

Searching the internet, I could only come up with the wingspan and wing area. But these seem to match.

Measured wing chord is about 11.75 inches
horizontal stabilizer span is about 27.5 inches
distance from front of firewall to rudder hinge line is about 43 inches

Here's some photos

Winspan and wing area match the Astro-Hog. I'm wondering if the other dimensions also match the Astro-Hog.

I promise you that is not a PT-19 kit of any sort. It is a modified something or another. It looks like it has the same type stab construction, ie. it has the one exposed spar that is used as the high point of the "airfoil" that is created when the stab is covered.
It does look to be a rather nice kit bash for that stand way off scale look, but in reality it is not a Pt-19, 16, 22, STA etc.

Yup. Sig Astro Hog made to look like a PT-19. The tail surfaces have been altered, the wing is recognizable as an Astro Hog.
