Stuntus Loudus at Reading, PA Flying Dutchmen field

Ken , man that was very cool! talking about not missing a lick or letting up   was it me or did it get faster and faster as it was going through the maneuvers   Thanks, Getback   

That's about as good of a pulse jet run as I've watched. Dan can really bust out some wild laps. I also watched the home made twin inline Fox flight. That's a great video, and the big platter plane too. Lots of laughing going on in the background. Thanks for posting.

Ken,

Thanks for posting that video. What diameter lines are used? And how much fuel does it hold? That run was just over 3.5 minutes.

TO answer a few questions, Dyna Jet engines can be a bit fickle. While there's only one physical moving part inside of it it can shut off at any moment. This is usually due to disruption of fuel delivery. The jet stunter concept was done in the early sixties. Dan decided that he was going to recreate this although there was many missing details from the 3 pages within American Modeler. In those 3.5 minutes, the jet burns a total of 19 oz's. The winds were up when we were flying this and Dan will play the plane into the wind to get some more speed. This certainly could've been responsible for the added speed in the maneuvers. One important factor however is that towards the end of the run, you just took all that fuel load out of the nose. That's a ton of nose weight that's disappearing at a ferocious rate. The lines he's using are .021's. I never personally flew this jet. My son has and he was telling many there about the line tension.

I don't think my shoulder could take that even for the short duration so I will just stay at the sideline and help or watch. I had my 1/2A speed stuff out yesterday which worked flawlessly and NO VIDEO. Any other time I'm fiddling for an hour, but yesterday it went off without even a needle change, go figure. I was hoping we could've had some video. I also ran the .40 size rat racers. The summer looks promising so let's hope we can get some good video. I love watching it and enjoy participating in it. The fellow who took the video yesterday was a control line returnee. He took some time off to race cars but were all glad to have him back. Ken

Thanks for posting Ken. The jet is fantastic! I was also very impressed with the videography! That guy tracked the airplane extremely well, albeit I threw-up my coffee after watching!!   Too bad you didn't get vid of your 1/2A speed flight. It always seems that the best flights happen when nobody's watching, you're alone.. or nobody shoots a vid.

I saw Dave Cook at the N.E.S.T. Control Line Memorial Fly-In at the Wrentham, MA field on Saturday. Dave's 84 years old and still really sharp! I brought my Speed model with me to show him, and he commented that he has "recent" plans drawn up for a .60 size stunt ship of the same airplane! I think he said they were published in "Stunt News".. and when I asked again where I could find them.. he said he'd email the PDF plan-set to me! Dave doesn't fly anymore, but said that he enjoys using his flight simulator at home. It was great to see him after 20 some odd years!

Another plus of the day was seeing the saucer fly. While for now it's just a roundy round, it shows some potential for stunts. My friend Dennis built this saucer which is a 1950's Paul Delgatto design. Dennis is quite the builder and in this past year he has built close to 40 planes which were all .35 size and up. A monumental task I must add. He builds many of the prototypes for the cottage industry laser cutters. Seeing that we weren't so sure how this was going to fly, we took it easy especially seeing that were over asphalt. I personally don't let that bother me, but I've completely shattered engines and that does bother me. We had a original kit saucer which we just threw some Monokote on and went out to fly prior to building this one. It was pretty horrific as the plane launched skyward and then flew clear across the circle jerking the lines only to do it again across the circle. Good thing for a positive bellcrank mount. THis one though with leadout changes flew pretty steady. https://www.youtube.com/watch?v=oh1nNKgyMbY  Ken

Cool Ken,

What engine does that thing have on it? It really hauls the mail when it leans out.

The engine was a Enya .35. ken
