I am curious. Of the conventional/or modern type P.A. national's winning models . What was the Largest model to win and what was the smallest model to win?
-
I think Werwage's P 47 Razor spans 63".Though not NATS, it did win WC in 04. Not sure of the spans of the T.P., Star Gazer,Impact and Infinity. I'm trying to go from 1990 up. D>K

I'm thinking Bob Gialdini's Eclipse (1965) may have been the biggest in wing area. The smallest post OTS era; probably Gieseke's Nobler, or (if you include Junior & Senior Walker Cup winners) Werwge's Ares (1959?) or Palowski's Atom (1958).

Thanks guys
I would think of modern as 1970 something.
I was thinking that Gene Schaffers' STUNT MACHINE, might be at the smaller end but wasn't sure. While Al Rabes' SEA FURY was on the large size. Though I was not sure if any other stunter were Bigger either in wingspan or pure mass.
I was curious if any small models have worked well enough to compete against the 40+ powered stunters. No particular reason but curiosity here.

I would imagine Windy's Russian Sweeper was the biggest in the modern era (and very cool, too), though he didn't win (placed 4th or 5th, I think). Paul's B-17 is more than 900 square inches, but he didn't win with it either. The Spectrum, Impact, TP, Infinity are all around the same size wingspan wise (within an inch or two), though I think the TP is around 660 squares and the Impact is near 700. Hard to tell the smallest, but I think the above is probably right. A Nobler derivative of some type.

The Impact is 675 according to Autocad by 6 decimal places. H^^

Your question was about the sizes of Nats winning airplanes. Though Gene Schaffer and his Stunt Machine were a formadable combination, Gene never won the Nats. He is often credited to be one of the best, if not the best flyer to have never won the Nats. He did place first at one of our Team Trials.

I don't remember the exact numbers, but for the last few years, the larger planes/engines have dominated the higher classes at the Nats-----according to the stats published in SN. Larger planes would be 625 sq. in. or bigger; larger engines would be > .51.
Not sure this means anything, but is sorta interesting.

I would wager that ob Baron's Patternmaster as the largest to win.....
Probably the smallest recent winner was the Geiseke (?) Nobler....

I agree.

Depends on which one. Paul's last year's version (2007) was 750 square inches. They have varied between 675 or so and up to 750. But the most common one is the 690 square inch one. Pretty much the one he is currently flying at the World Champs.

Is there a limit to how big or small the airplane is?
-
On the AMA site, I see a weight limit of four pounds for control line models.
Didn't see a size limit, but could have missed that part.

Paragraph 8 of the General Control Line section of the AMA rulebook states "Unless otherwise permitted under specific event rules, no Control Line model shall have a flying weight of more than four (4) pounds."
In the Control Line Precision Aerobatics section of the AMA rulebook, there is a statement at the bottom of the line size and pull test chart that states "Maximum model weight is 3.5 kg (7 lbs, 11 0z)." Also, Paragraph 2.4 also states "Maximum model weight including any batteries but excluding fuel is 3.5 kg (7 lbs, 11oz)."
It is sometimes worthwhile to read all of those areas of the rulebook that affect this event.

Keith is correct----and I should have posted all the info concerning weight, or none of it. :-[
At only 6 feet and 200 pounds, I ain't quite big enough to fly a 3.5 kg. CLPA model........... :o
