The first RC I built was in 1979 was a PT-19. I ordered the kit from some mail order hobby shop in the LA area along with a Fuji 25. I think the kit was built about twice the weight it should have been and the engine was about 1/2 the size it should have had. It did not even power enough pull the tail up much less go fast enough to get off the ground and fly. I didn't know any better. 35 years later and somewhere in 50-60 kits built later I would like to build another PT-19 in either a 40-60 size but can't find either a kit or plans to scratch build. Any and all suggestions would be greatly appreciated.

The AMA lists plans for two pt-19 models at spans of 48 and 52 inches. Certainly these could be scaled up or down as desired.
I'm guessing a Sig Astro Hog could be "bashed" into pt-19 shape as well.

Thanks guys for all the infor. My son found plans for a PT-19 with a 62" wing which should be about right for a 61 engine size. He burned them to a disc and I will talk to one of my club member to reproduce them to size. I will try my hand at scratch building, which I have never tried. Should be an interesting project over the winter.

As stated above, the Astro Hog kit bashes well. I have one with an Enya 80 4 stroke that turned out very good. Here is a picture.

Rubbernecker, I don't remember who put out the Astro Hog. I checked on both Tower and Sig but no Astro Hog. I have plans for to scratch build one in the 62" wing span. Should be just right for a 61 AX to 75 FSR

Sig makes the Astro Hog. Advantage Hobbies carries them. http://www.advantagehobby.com/72605/SIGRC55/?cat=165 Sig's web site sucks.

On Sig's web site: SIGRC55 SIG ASTRO HOG KIT EACH $109.99

Let me know if you go that route, I may still have dimensions for the bash. Also I used the Great Planes Stearman windshields and painted them silver. Needed a little heat gun work but turned out good.

John

I thought Sig produced the Astro Hog but when I first checked their list I did not see it. This time, however, there it was. Senior moment!! The specs on the Astro Hog are slightly larger than the PT-19 Plans I took off the net. I have never scratch built a plane before and think it would be fun to give it a try. By the time I enlarge the plans, buy the materials, redo the numerous mistakes I will probably make, it is probably much cheeper to modify the Astro Hog kit. Anyway,thanks for all the help.

keep us posted, please. The PT-19 bash looks very appealing. Oh wait, it was that beautiful model of Rubbernecker's!

Hey guys!<div>
</div><div>Ron here. Just joined the site, and just got an Astro Hog kit from Sig in the mail today. I have a considerable amount of model-building and woodworking experience, but this will be my first RC build! Hoping you guys will be gentle with me. </div><div>
</div><div>It's serendipitous that I found this thread, as I'd scoured the web looking for a PT-19 kit, but as you all know there were none to be found. I ordered the Astro Hog figuring I would just do it up in the trainer color scheme since the shape was similar. After looking at the plans, though, it does seem like it would be pretty easy to modify the Hog with dual cockpits. If you can post or email the dimensions for the bash, Rubbernecker, it would be way helpful!</div><div>
</div><div>I plan to install a 4-stroke engine, and I was thinking of mounting it inverted to give the cowl a little more PT-19 shape. Does that seem feasible?</div><div>
</div><div>I look forward to seeing what you come up with, Matadco...and to pumping you guys for info to help with my first build! </div><div>

Ron,
First cockpit opening is 6 - 1/8 inches from F1 and the second is 13 - 9/16. Obviously you will need to build floors for each. I also used Great Planes Stearman windshields. Took a little head gun work, but they turned out good. Also reshaped the rudder based on a side view of the PT 19. Good luck and do what you can to make the tail light. Mine required a nice chunk of lead to balance with an 80 4 stroke. Also rake the landing gear as far foward as possibe, she likes to nose over.

John

A tip or two to keep in mind when building the "Hog" bashed or otherwise.

1. Drill the holes in the former in which the wing dowels are fitted before building the fuselage. This will make fitting the wing much easier later on.
2. Remember a tail dragger version of the "Hog" requires longer landing gear wires for prop clearance which is not included in the kit.
3. Consider using 3/16" music wire for landing gear as the 5/16" wire provided is more prone to bending back from landing. (A wider landing gear block will be needed to accomodate 3/16" wire which is available from Sig).

Good luck,

DaveB

Found plans for a 62" WS on net. It is a Gene Rogers design. Had the plans printed full size. Now I am in the process of trying to compute just how much of each type of wood I will need. I have never built a scratch bild before. First time for everythng! One in my club suggested I cut out the ribs and formers from one of the two sets of plans, glue them to the wood as a timplet. Others suggest dracing them out onto hard material and trace around on the wood. Looks like it will take most of the winter to do this. Of course any suggestions on procedure would be greatly appreciated.

If you own a wood router... do a you tube search for illustrations of how to use it to cut the wing ribs.

There was a scratch build thread for a PB-Y Catalina I was following recently, and the builder used a technique of photo-copying the plans and using an iron to transfer the pattern onto the wood. I can't seem to find the thread, though. He did say that it was kinda hit-or-miss, in that the printing didn't always transfer completely. Still, it's probably much faster than cutting out all the patterns and gluing them to the wood.<div>
</div><div>~ Ron</div>

A router is the only tool I did not feel I NEEDED. I have accumulated a lot of tools over the many years but the cost of a good router, table and bits plus I never saw a need for it in building RCs until now. I'll just trace the pattern onto the balsa sheet and use ether the jig saw or the band saw to cut them out.

Ron, I am going to try to find that Catalina build thread and see if I can't get some ideas. I have built a lot of models over 30 years but it was always with plans, pre-cut parts and building instructions. I think I will trace the ribs and formers onto thin cardboard and then trace around it onto the wood and saw them out. Someone suggested tracing them onto formica but a 4X10 sheet was $125 at Lowes and the would not sell anything smaller. I only need about 2 square feet not 40. I tried a piece of thin floor tyle, but that doesn't work to well either. Of course any and all suggestions are appreciated. I will try almost anything once.

If you want to get something like the stately flight of a PT-19 you would need to build that model light enough to fly on much less engine. A .61 on a 62 inch PT-19 would be more like a Kaos...except with a thinner airfoil and a shorter fuselage! Plus I think the engine would stick way out of the cowl.

Well I finally started on the build of the Gene Rogers PT-19 plans/design. Copied all the wing ribs, 10 per side, onto heavy paper. Actually it was file folder paper. Got all 20 of them cut out of 1/8" balsa. On #2,3 and4 there is 1/16" ply doublers. That is cutting out an additional 12 front half of the ribs. I'm cutting stuff out on my jig saw but only able to work about 2 hours per day. Bending over that saw is hard on the old back. Of course after cutting out there is the edge sanding for uniformity. The spars are 1/4X3/16. The LHS does not have that size bass wood. I'm considering cutting the spars from 1X4 finished pine from Lowes. How will that compare to bass wood? The other side is to use balsa, but I question the rigity that balsa would have for the main spars on a 63" wing, even though it is reinforced in the middle with fiberglass. Comments would be appreciated, Also if any one has built this plan before,your comments would sure be appreciated also. So far it seem like it is going to be a real challange for first ever scratch built, just slow for an old toot.

hi

I have an old sig kit holingers giant rc scale pt-19.
have so many kits at 80 yrs of age know I will never get
to build them all.

would you be interested? if so will send addditional info.

Thanks flyer but right now being a couple years behind you I have my hands full trying to compete this project. First time had to cut all my own sticks, ribs and formers then figure out in what order to use them. Always before the parts were cut out and I had an instrucction book telling me when to glue what to where. Secondly, I really don't have an engine large eought for a giant scale. The biggest I have is the Top Flight Gold Edition of the P=40 and P-47. However, any instructions you can give would be appreciated.

ok matadco

it was labeled giant scale wub I think it is a 60 size airplane...not sure will
check this out and let you kn ow.

thanks and happy flying

pt19 flyer'

I built 2 of these years ago, It is a full build kit and are excellent fliers.

Ron

OK MATADCO-

LOOKED AT SPECS ON KIT AND THEY ARE AS FOLLOWS:
GIANT SCALE IN THE '60'S WAS APPARENTLY DIFFERENT THAN TODAY
SPAN 72" 1/6 SCALE
SIG KIT gs-9 sig hollingers scale pt 19 won several scale contest in 60's
engines listed were torpedo 29 and torpedo 35

advertised on ebay for $225.00 is interested I think I can do a little better than
that

happy flying
