Hi Naomi;
I never get tired of talking about the Cox PT-19. I have about a dozen of them in my collection. Through the years they came in the familiar blue fuselage and yellow wings, opposite that with yellow fuse and blue wings, white wings and red fuselage, and all white with frilly wing and tail stickers! The final version that they released was upgraded with a few improvements. Mike Pratt, who is a stunt grunt from way back and worked for SIG when he designed the SIG Magnum, also worked for Cox when they moved to Colorado and were owned by Estes. He made the fuselage thicker where it needed to be, thinner where it could be, added some plastic to the leading and trailing edges at the center section, and added tip weight. I always thought that the PT-19 flew pretty well anyway, but these little detailed improvements helped out a great deal and only increased the weight about 5 grams. If you look at your model, you will see that the elevator horn has two hole locations. The longer hole is for training and slows the controls down. The hole nearest the pivot gives you more control. look at the nose also, and you will see that the engine mount c an be adjusted for a lot of down thrust for beginners, and then moved up to almost level for more experienced flyers. It is capable of big loops if you do not over control. It will stall at big elevator deflections like a Ringmaster. Put about 1/4 to 1/2 ounce of tip weight on the outboard wing and that will help keep lines tight for any beginners. The tank won't allow extended inverted flight and I never tried any outside tricks with any of mine. I don't know how that under cambered wing would react, but keep in mind that it is a trainer!. Mike brought out a stack of them to Oshkosh one year and we left the landing gear off, glued the wing and engine mounts in with silicone and added a small #2 sheet metal screw in a few places. Mike equipped these with some TD cylinders and glow heads so they made some extra power, enough that they would fly well out on 45 foot .012" lines that we used for the Skybaby models in use at that time. Do a search on the 1/2A section of Stunthanger and some one has designed a replica of it using plastic coreplast material and it looks like the real thing! A lot of people hate these and cuss the engines, but they are one of my all time favorites and wish they were still available. They have been out of production a long time, but watch for them on eBay and see what some people will pay for one! Even after being out of production for so long, there are still people who go into the hobby shop at Christmas time looking for " That little yellow and blue gas powered airplane my Grandpa, Dad, or older brother had when they were kids! If you can't find good 1/2A fuel, any decent 15% fuel with some castor oil in it will run in them. I have even run some of mine of Fox fuel when I had too. Good luck and have fun with the little cutie!
Type at you later,
