It was no problem and I had a superb flight to Cardiff direct from EDLM. Nobody wanted to see it, or even my passport for that matter! On the way back yesterday we met up with Dave Bosomworth in the air over Goodwood as he had heared us on Solent Radar frequency.

But is was not reality this time: when I took power off during a long and high final, it was really off. So it was a glide abroach but only because I wanted so (and the engine was idling).

The strip was very short (w wet long grass) and a sidewind was at uncomfortable level. I triplechecked everything before takeoff run: 1) prop T.O. & auto 2) 2nd fuel pump on 3) both mags on 4) trim there where I like it to be with that configuration and load and selected =9Cstick=9D and =9Cfast trim=9D 5) doors locked and pip-pinned 6) loose items secured 7) free controls 8) necessary lights on 9) xpdr on 10) TCAS on 11) no red lights 12) runway seems to be free During acceleration: 1) engine revs at or near 5800 rpm 2) ASI is alive During my CS-prop test flight period I tried couple of times what happens when I do so (leave it on manual during take-off with full power). Both times the departure run was quick and engine rpms were after rotating around 6500 rpm. Second time I tried it until at 1000 ft QFE. Rotax was singing smooth and no noticeable problems at all. I have heard a gossip that Rotax factory accepts this is ok for =9C a moment =9C but of course they will not publish it. Do not take this very seriously or literally or at all. Anyway, I would be not so worried about overrevs with Rotax (912S).
