Doug, I totally agree. What would be interesting after flying is complete today is to compare the normalized scores after 4 flights to the TBL with normalization scores. This might tell us something about TBL and the scores being thrown out. What I don't know is if a spreadsheet with the raw scores will be posted today (as has been done the last 3 days) or if the officials will only post the TBL corrected and normalized scores after round 4.

Thanks guys for the raw score calculation! I realize this is just speculation but fun nevertheless. Pay attention to Lassi Nurila from Finland who is most probably going to make it to the semis.
By the way, while the Trigantic flight posted above looks good and graceful in many aspects, there are some serious errors as well. The snap roll, spin and stall turn are not good. However, he has been getting pretty high scores...

Thanks Claude! Something new in the pipeline I see.

The spin was OK otherwise but it did not begin with a proper stall (referring to the Trigantic flight). It looks like he pushed to make the plane dive and then started the spin with rudder and ailerons. Correction: I just watched the video several times (the spin part) and the plane did stall just a bit but did not start spinning from the stall. Mayr then used the controls to start the spin...
In another note: Finland's Lassi Nurila is 10th after the preliminary rounds!

Team Point Standings after Prelims:
1 AUT = 30 (7 11 12)
2 JPN = 32 (2 9 21)
3 USA = 36 (8 13 15)
4 GER = 46 (4 19 23)
5 FRA = 48 (1 20 27)
All five of these teams have 3 pilots in the semis, so the team standings may change alot over the next few days. Hopefully USA will fly some killer F sequences during the semi-finals and get three pilots in the finals!!!

CPLR's spin however was VERY good. The airplane stalls, and the rate of rotation is stable. His snap roll was also very good. CPLR's Galatik is a HUGE airplane too. I didn't realize how big until I saw Benoit carry it out to the flight line.
#86
Yeah, you may be right and the more I watch the video I tend to agree that it is a spiral dive and not a spin. However, there is a tiny stall in the beginning (or something that is made to look like a stall) but it does not make the move good since it drops both of the wings equally and the spinning must be forced after that (= spiral dive). Obviously many of the judges did not see all the problems.

Hello
Flight of CPLR to compare snap and spin !

Huge differences between the two pilots in the videos, and apparently duly noted in scorecards. I wouldn't want to be either judge nor pilot in those winds.

Seems like pretty fair handling of the mild breeze....I'm sure everyone noted the wind sock and flags both standing straight out trying to rip themselves apart. Looks like everyone had some pretty horrible conditions today.

the day will come when the little black box will cost $50.00 and USB plug into a 'puter for an excel file to
crank out....
"Smoothness" can be quantified.... it is the lack of abruptness right? So smoothness can be measured by the
amount or magnitude of accelerations above and below the accelerations required for the maneuver....
The triplane reminds me of the razers (for shaving) in the US... soon there will be a 4 winger.. then a 5 winger!!
Would the rules restrict a device that initiated a stall, (Like spoilers for example?) for Spins and snaps?

I watched CPLR's snap at about 3:50 in the video.... in pattern... is a Pitch Departure BEFORE the rotation required?
It looks like the rotation and departure are simultaneous.... Don't get me wrong.. I loved his snaps... but in other aerobatic
genre.. the pitch departure is at times accentuated... or seems so....
(And why hasn't the contra caught on??? seems like eliminating a source of asymetric forces would be a welcome thing no?)

Contra has not caught on because it is too expensive and asymetric forces is not a major problem in RC models.

Silvestri is flying a Contra and has for many years. There are several pilots who are flying them actually.
Price is a big factor for most people, but availability is another.

Contra-drives aren't easy nor quiet on IC models. As CPLR flies YS, he won't run it. There are still a lot of people who mimic what CPLR does to minimize the variables, even though the biggest variable is his skill and dedication, which can't be purchased.

In the absence of official data I have put this together ;
27 Semi-finalists.;
YS ; 4
Electric ; 21
Don;t know ; 2
Of the 21 or so Electric I believe 6 are Contra drives.
There are a few more that did not qualify.
If compared to YS at this level I'd say it has if fact caught on.
Furthermore most of the YS's at the WC's are sponsored !!.
