Thanks - I guess the photo is not that great. The front opening to the cowl is about twice as wide as the cylinder (difficult to see), and the outlet underneath the cowl (not visible) is at least wice as big as that. But I guess I still need to open up the area in front of the cylinder head. I am not sure if openening the whole front of the cowl would improve the situation a lot, as most of the air will just pass the engine and it needs to get out again.

I'm just wondering if anyone with the FS200 has had similar temperature problems...

The hole in the back is really annoying - it has leaked a substantial amount of oil from the very beginning. Hans Meij in the post above had similar problems, and another guy from Germany reported his engine had started leaking after some time, too. Former Webra engines had a screw in there that sealed the hole nicely, I wonder why they left it open on a quite expensive engine as that.

Cheers,


Christoph
