I am restoring a PT 19 which I got from a sale. The airframe is good and I have recovered it. Does anyone have plans for this plane showing the CG. I have not decided gas power or electric yet. Any comments?

I would go gas,a DLE 35 rear exhaust would be a great match.It all depends where the engine box is position from firewall.

The CG is 4 and 3/8 inches from the leading edge. Good Luck, Dave

thanks for the info grumpy

I thought the Dynaflite PT-19 had an 86 or 87 inch wingspan. If yours is truly only 82 inches, then the plane may be either a Hanger 9 or a Great Planes, both ARFs not kit built models. Recheck your wingspan size.

For plans for the DynaFlyte PT-19, please contact:

89"

Thanks Luft-Gangster, I knew it was larger than 82" and nobody clips the wings on a scale PT-19 (do they?) so if it has an 82" W.S. it's not a Dynaflite. It's likely a Hanger 9 or Great Planes ARF. Photos of the inside fuselage structure would help to pin it down. I have the Hanger-9 ARF and could compare the photos to mine if the OP is interested. The Dynaflite C/G spec will be wrong for the ARFs. Or the OP could measure the wing cord of the root rib, measure the wing cord of the outermost rib (ignore the wing tip), average the two measurements (add together and divide by two), (this is the Mean Aerodynamic Cord) and then use 25 to 33 percent of that number for the C/G range. Start flying at 25% of the MAC and adjust as needed..

I am currently scratch building a Jim Pepino PT-19 at 87" among several others.

Yes you are right, this is not a dynaflite PT 19. I cannot tell if it is a hanger 9 or a great planes. Is yours powered with a glow engine? If so where do you have the fuel tank located ? This one has a recess located under the front firewall that just fits the fuel tank that came with it but I an sure this location would be too low . I think this plane is worth some effort to get it flying as I am told it is a sweet flying plane. Any comments? Thanks Grumpy

grumpsod, Ok let's see if we can identify what you have there. The Great Planes PT-19 and the Hanger 9 PT-19 are like "peas in a pod", nearly identical twins. Both ARFs have nearly the same physical measurements so it will be hard to tell by just wingspan and length with a tape measure. Often the dimensions given by the manufacture aren't exactly what the actual model measures. G.P. says their plane has an 82.5" wingspan, and Hanger-9 says theirs has an 82" wingspan. Mine IS a Hanger-9 and I measure my wingspan at 83". See what I mean? Manufacture length specs are G.P. 64.5" and H-9 63.5". Don't know if they count just to the front of the cowl or with the spinner. I think it is intended to be just to the front of the cowl but of course that number depends on where the assembler mounts the engine and then the cowl. My H-9 measures 63.0" front of the cowl to the rear of the rudder, 1/2" less then the H-9 spec. Mine measures 48.0" from the rear of the fuselage (not counting the rudder) to the front of the firewall not counting the wooden motor mount box extension that is inside the cowl when assembled. OK, yes, mine is glow powered and my fuel tank is in the stock location inside the previously mentioned wooden motor mount box extension. It sits high in that box with the top of the tank at or near the top of the inside of the box extension. There is a round hole in the front of the box for the nose of the fuel tank to poke thru. A two piece aluminum motor mount bolts to the actual firewall at the front of this wooden box. I don't know, but I would bet the G.P PT-19 was supplied with a black nylon Great Planes motor mount. Don't know if the G.P. had a similar wooden motor mount box inside the cowl. If your plane still has the original covering that may help. The H-9 plane came with decals (stickers) to put number "47" on the fuselage sides and cowl. The G.P. came with decals for number "24" in the same positions. Of course the assembler could have changed or omitted these numbers. I changed mine to number "42" to match my TX channel. Another minor difference in the trim is the vertical blue stripe on the front of the rudder. The H-9 is a constant width stripe from the bottom to the top of the rudder with a small area of yellow on the front top of the rudder. The G.P. has that small area on the very top of the rudder as part of the vertical blue stripe, so the front edge of that stripe has a jog in it at the top. If your plane has been recovered then this covering info won't help. The GP is covered with MonoKote, and the H-9 is covered with Ultracote. Hard to tell apart on looks. Go with this info and get back to me, and we will continue.

Thank you 52 larry for your detailed reply. I am leaning towards thinking this is a Great Planes PT 19. I stripped and recovered it recently so I cannot tell if it was MonoKote or Ultracote ( I like Ultracote much better than MonoKote ) and I did not notice the stripe on the rudder. Mine has the number 24 on the cowl. The wingspan is exactly 82 in. The fuse length ( not incl. rudder ) from rear to the front firewall ( not incl. motor mount plate ) is 51 in. I have located the correct location for the fuel tank thanks to your description. It does have a black nylon motor mount. I an concluding this is a G.P. model. I am looking foreward to getting this in the air. I would imagine your flying season lasts all year. I shut it down Dec/Jan/ Feb as it is colder here.

What size engine are you using? . I would imagine this is a reasonably docile plane to fly ??? I fly both glow and electric. I have a 1/4 scale cub on electric that I am very pleased with. regards Grumpy.

grumpysod, Your welcome for the help. I agree with your conclusion that you likely have the Great Planes PT-19. If you go to the site that Bax suggested in post #8 you should be able to download the information you want from Great Planes (same large company umbrella as Dynaflite). I have an O.S.160FX in mine, inverted with a Slimline pitts muffler. (More than it needs) Our flying season here in west/central Georgia does go all year but with interruptions in the winter on a day to day basis. I last flew on New Years day. It was clear sunny skies little wind and in the low 50's, nice! I was supposed to fly today with the same forecast and high 50's, BUT suprise suprise, we had 33 MPH winds! Flying for me was cancelled and the Cub put back in the hanger. Maybe next weekend. I researched your location in B.C. and you are not to far from another avid poster here on RCU, that's "bikerBC" in Sorrento, B.C. I have have not had the pleasure of visiting western Canada but it sure looks like beautiful country in the films I have seen. All the best to you.

Thanks larry for your info and interest. Grumpy
