Also, “wing(s)” are plural in the rules and “stabilizer” is singular.

This link for results from last Fall is understandably dead, but is there something equivalent for yesterday's invitational at Crystal Lake Central High School (Illinois)?

Edit, got it: https://app.avogadro.ws/il/crystal-lake ... ts/overall

I don't really know what to make of it because there are no raw scores and it looks like some of the competitive local schools didn't participate. It does look like we could improve our chances of going to State if I offered to coach the ping pong ball and the car events. I wouldn't normally but it sure would be nice to get under that 98' ceiling! Luke says we'd need to be in the top 1/3, and it looks like were near 50th percentile. I really should have read the rules better when we started, I thought individual events advanced, not whole teams (stupid, in retrospect)

And looking at some of the other topics/scores, it seems hopeless :(.
1st place got about 1:08 both ways, but I don’t know about the rest. It was a pretty tall ceiling, though, I’d say about 25-30 feet

Edit: first place in large school division, which was 2nd overall, or so I heard

I would like to know also. Word must be out by now.

All I'm able to glean is that effective ceiling height is 28 feet and Troy High School got the top times. I'm guessing at 28 feet, they might have gotten over 2 minutes.

I do not know exactly how long the top result was but I think 3rd place (not me) got around 1:20 one way and around 1:10 for for the other.

That's 2 minutes both ways, right?

no, combined. Wright stuff is just super difficult this year and the top teams arent getting good scores

That's the prevailing opinion. This wasn't your point, but I've noticed some experts are really unhappy about it.

This year is just different.

In years past, WS would change some minor parameter like the maximum wing span, but the same general formula applied and experts could crank out a winning plane within days of the rules being posted. The rest of us beginners benefited from generalized advice and enjoyed some nice flights, but winning was out of the question. This year it is hard, but it's hard for everyone, and that's good. We are total beginners and we find ourselves in the same range as the best-coached teams.

IMO the new rules didn't ruin WS at all, they may even have saved it.

We have gotten lots of help to get started, but we've also noticed that traditional advice doesn't fully apply this year. We have shared everything we've learned openly, knowing that others are struggling, and knowing even the best teams can benefit.

We think this year has been a total win-win, even if we don't win.

I hope future rules are equally challenging.

We were trimming the other day and something interesting happened. I'm sorry that we don't have a video, we weren't recording at the time.

Our plane started to climb but the radius was too big. It hit (sort of grazed) the wall and instead of recovering, it dived straight down to the ground and the prop broke. Why is this?

We have a ff monoplane, with about 3-4 mm of incidence. The rudder was about 5 degrees to the left and the cg was 1.15 in forward of the trailing edge of the wing. We were using about 2g of .065" rubber at 100x15 winds.
