Thanks for the link to the other thread, I had not seen that before. It seems there is not that much experience out there with the engine up to now, but I am inclined to buy it rather than the 160FX - the EF Yak is a 3D plane and my experiences with my other 4 stroke engine (Saito 100) were extremely good, especially for responsiveness and spool-up.

I do have a couple of weeks before I need to get the engine, so I'll follow the discussion to see if more interesting stuff comes up. Hans, if your engine is broken in it would be great if you could post your experiences!

Thanks,


Christoph
