Yes, both Christophes planes have the 200S. The original plane is 5020 and the second one is well under as Claudes photo shows. Noise level was 92db.
Cedric Carayon did have the S, but has broke 2 cranks, so is using the standard 200 for now. CPLR hasn't had any problems.
One opinion says it has more power and one says it is the same. It has smoother transition and spools up quicker, so maybe this gives the effect of more power?
Now for the changes. There is consensus on 2 changes, so these are pretty much a certainty - Different crank shaft and different piston. I don't know what is different with the crank. The piston is lighter and a different shape, to give a better combustion burn. So with less inertia, it would spool up quicker and smoother.
Now for the maybe changes. A new rotary disc with altered timing to allow more crank case pressure through which should create more power? Also, throttle barrel was mentioned, but this one is the most vague. The engine will be available at the end of August, so once a manual is available, we'll know what is different.
Please note these changes may not necessarily be 100% correct, but seem to be fairly accurate.

Hello Scott
Cédric told me rpm is about 200 t/mn upper (with same prop !)

Yes, Christophe said maybe 100rpm higher.
From what I'm hearing, I think it does have a bit more power. This is good 😁😃🙂

Hi Scott,
Thanks for the quick response. Are there many non electric power models at the WC? I had read somewhere that the Japanese had gone 100% electric, is that true?
Interesting comments about the Oreka, but not surprising. I guess his Skybolt design was just a diversion. The real test always seems to be the unknowns.
Thanks for all the updates!

Hi Scott,
Thanks for the videos. I do not envy your job as a judge trying to find mistakes in their flying. Two very nice flights. The sun looked to be in CPLR's box which can be very tough for both pilot and judge.
CPLR's YS seemed to run very well.
