Hi Kang,

More good pics - thanks Cheesy. It's good to see more US flyers building 35 cm models. I'd be interested in more info if you can scrape it together. What do these models weigh? It's hard to build light without Y2K2 so some of the pics seem to show mike? I only ever built one 35 aeroplane which weighed 0.4 g with VP and flew 28 in Bordeaux some years ago.

I wonder if more interest is due to official FAI status. It'll be interesting to see if more flyers enter the 35 cm contest in Belgrade this year.

Nick.

Tom I. had a mic covered 35. I believe he told me it weighed 275mg. It met some kind of unfortunate fate but the details aren't clear. I think his best official flight was made with a Mylar covered ship.

275 g is very light but mike is so fragile after the luxury of plastic - it goes 'pop' if you look at it and is more difficult to repair; especially if it's a braced model.

here's a pic of one of my 35 hubs.

If I'm not mistaken, Whittles' model, which was nothing but a clipped-wing EZB, weighed 300 mg. I don't know what he used for covering other than that it was plastic. Like I said, not sure it was Whittles' but he's looks the part, and someone showed me a 35cm built off an EZB planform that was 300 mg.

I used to wonder whether it was worthwhile making hollow sticks/booms for 35 cm models. I used rolled wood down to 007" X 3.8 lb for both components but some of the USA rules EZB's with solid sticks/booms are lighter than 35's with OS covering, roughly similar area and solid prop blades.

Does make you think, don't it? I do think a rolled tube motorstick is still better, though, because it will allow you to use more torque in the long run. EZB's do like to twist themselves up.

I went this route with my 35s. My solid motorstick was from 3# wood with 4 borons and a bracing wire. It's something I want to work on again.

I have been out of 35cm and know nothing of the class (or records) since Bob Bailey's design was featured in INAV, about 2004. Have there been any changes since?

Thanks,

1 rule - 35cm maximum span (monoplane)
OK that's 2 rules.

Thanks, Bill. I think the FAI recently added 35cm to their indoor list. All I found earlier were UK rules, which had complicated the class with a third rule: "no microfilm".

the official FAI 35cm rule is "no microfilm".  In the U.S., some still fly with microfilm, e.g., Tom Iacobellis.  See a picture of his model in an earlier post.

Kang,
Is the "no mic." rule in another section? My eyesight is bad but I didn't think *that bad*.

A little side info:
Nick Ray was planning a world record attempt for 35cm at Lakehurst on the weekend of the F1D team selection finals. When FAI told him they were not in the business of recognizing 35cm records yet Nick decided that instead of scrapping the trip he might as well try for the team - and made it.

(Hopefully I haven't scrambled the facts too much here)

Bruce,  My eyes are bad, too, and I can't see the "no mic" rule in the document.  My bad.

I'm unaware of any GB ruling of "no microfilm" for at least the last 10 years.

The current BMFA rulebook is quite clear - the only rules are
Quote
Characteristics of Indoor Model Aircraft
Maximum wing span of the monoplane model: 350 mm.
This is exactly the same as the FAI rules for 2012 and there's no mention of allowing or disallowing any covering material.

The FAI has recognised 35 cm/F1R as an official class for some time - I wonder why they aren't recognising records for it.

Nick, All: I quit! I am insane, touched, dementia-ized. Amazing, I can still find my way to this forum!

Did I already ask why you are green?

Hi Bruce,

Don't worry I feel similarly afflicted on a regular basis.

'green-man' refers to my indoor balsa sheet cutting operation. The machine I use was originally built by top GB indoor flyer Ron Green. So, 'green-man' is a composite of all of Ron's surname and half of mine  - Aikman (Scottish Gaelic for a keeper of oak trees). It was Ron's expertise that devised the machine and all I do is throw lumps of balsa at it.

In addition, in English pre-Christian folklore, the Green Man was a pagan spirit of rebirth and guardian of the forest.

Well you did ask!!!

That's the end of my free plug for the evening.

Nick ((:-{o))))))))))))))))))))))

Somehow, I wandered back here and found your "Green-man" explanation, Nick. I do like the explanation you gave. A lot.

Thank you, much

I returned from a meet at the Kibbe Dome in Moscow, ID last week. Someone was explaining the name of a balsa cutter in the UK and it's origin, but it did not contain all of the details. I find it wonderful that you are honoring your good friend who has passed on with his name and the "colorful" details associated with the name.

Thanks Ron. The name seems a bit bizarre as it doesn't relate to the balsa cutting in any way but it feels right to me somehow.
