    I see in 2011 the Goldberg Viking will be the “one design” model flown at the NATS. I wasn’t flying when this design was popular. Was it a good performer? I don’t hear it mentioned with the same reverence as T-Birds, Stardusters, Galaxies or Satellites. I would be interested in hearing of your experiences and any quirks the model may have in preparation for 2011.

    Greetings Stardust,

    I’m looking at scratch building the 1/2A Viking for 2011. I have studied the plans that I have and I don’t like the design of the spar in the stab. The stab spar is laid in the ribs the wrong way to me. It looks like it will warp in a “smile” looking from the TE fwd.
    I need to go through the rules a bit more to make sure I get everything just right. I’m pretty sure that I can change that spar to an upright position but still need to make sure that I can per the rules.

    I have witnessed the 1/2A Viking in flight and it looked to be a good floater. The model was money coated (monokoted) and I thought it could have been a bit more competitive being tissued etc.

    I’ll do my best to keep in touch on the progress.

    I just built the Goldberg Viking. It was the answer to the Satellite. It has very good airfoils. 330 square inches, so you will need a strong TD to power it for the Viking event. The reason it was so big, because it was designed in the era of 173 ounce/cu inch rules. About the time the kit came out, they dropped those rules. Same reason for the Satellite 320.

    I had concern about the stab too, but it turned out nice and flat. Covered it with UltraCote Lite.

    Beautiful model Dave….excellent craftsmanship. Would you happen to know what the finished weight is?

    I used ALL of the kit wood and that was pretty heavy. It came in at 9 1/2 ounces ready to fly. In it’s day, the requirement was for all 1/2A models to weigh 8.65 ounces, so it was pretty close to the target.

    It is a very big 1/2 A model in the 330 version from the Goldberg kit. I also sheeted the center section of the wing above the wing mount.

    I doubt that the 330 can be built to 8 ounces, and the performance gain would be negligible, in my humble opinion. As you can see from the picture, I am not fussy about equipment like timers, I use what I have more of, like KSB timers that are heavier.

    When I am building these NOSTALGIC models, my only intent is to make them rugged for long life. I don’t intend to build them ever again… I keep saying that!

    Thanks Dave for the weight update.

    I’m trying to understand the nostalgia rules more for the “one design” contest. I would like to install a Cox TD 0.49 with a Kustom Kraftmanship needle valve assembly with a lightly modified venture. Is this legal?

    Also. I’m reading that the nostalgia weight rule for the “one design” contest is 100 oz per/cu inch displacement. I hope I’m doing the math correctly and that would mean that the model needs to weigh at least 4.9 oz ???
    If I’m incorrect, please school me. I just want to make sure the model meets all the requirements. Most of my 1/2A models come in around 6-7 oz tissued.

    This “one design” contest is a neat idea. Sounds like a lot of fun.

    The Viking is not a Nostalgia era model. It is one of the models picked for Bill VanDerbeek’s one design class for the year. Rudy Kluiber also has a one design contest at Muncie sometime late summer, and features all of the one design years somehow? The one design event is held at the Nationals each year, last year the Spacer event was flown.

    Nostalgia models are pre 1956 approved models. Anything after 1956 and up to 1970 is a Nostalgia model for most of us, but does not qualify for Nostalgia. Since the Viking is just a one design event model, it can have a TD 049/051 of any configuration, so you don’t need to worry about needle valves or heads. The Cox TD engines are not Nostalgia legal, except for the 020 for 1/4A NOS, and it is the only engine used.

    Concerning the weight, you can make it as light as you want. I was just explaining the basis and rules for which the Viking was designed.

    The ‘One design’ event and Nostalgia Gas are seperate entities.
    One Design isn’t necessarily legal for NosGas.
    The Viking isn’t legal for Nostalgia.
    I believ that he is allowing the viking to be scaled. I know that there is 250″ version as a kit available.

    Thanks Dan and Dave for the clarity.

    I was getting confused because under the 2013 “one design” verbiage it states that nostalgia rules apply. If ALL “one design” entry’s are as you state then count me in.

    I’m starting to feel my youth again….I just need to get a good chase bike.

    Running through the desert chasing models and dodging snakes isn’t fun anymore…<>

    Nos rules apply for engine run, flight times,attempts,and presumably BOM.

    I’m OK with that…

    I’m starting to look for my engines and timers. My “Ecuadorian Gold” is already accounted for and ready for the cutting.

    Thanks again,

    Just to bring you all up to date on the one-design meet. It will be held Friday, Oct 1 and is part of a big three day weekend including the one-design, the NOFFA annual meet on Oct 2nd & 3rd (25+ events) and a big FAC meet on the 2nd & 3rd as well.
    The one-design meet usually has at least ten separate events. A few of the less popular one-design choices are combined into one event, but the popular ones all have a separate event. We have a cook out afterwards on Friday after the flying. Everyone is welcome.
    Look for a flyer later this spring

    Hello Rudy

    For those one design events that are also NOS events, are the scores sent to NFFS for NOS points?

    Does your One design competition also allow for the larger classes, or only the indicated 1/2 A size?

    Do you feature any of the upcoming models in your competition like the Viking and Satellite?

    I can’t send in results for Nos Nat’l Cup points since these are separate events for a single design, not the entire 1/2A class.
    The events on the schedule are for each of the previous year’s choices just as they were flown at the time. They have all been 1/2A except for the A-B Honey Bee.
    I haven’t included any future choices. I would consider that if I could get an entire weekend to hold the contest. So far, I have only had a Friday to hold the meet and I keep the event total to ten. I combine a few of the less popular events together in a couple of cases.
    I’ll send you a flyer from last year.
    BTW – Can someone tell me why I keep getting two messages every time I submit something ??
