Thanks.
It looks like I should get a new engine anyway. The TT75S is idling around since I do not like the engine so much.
I try to look into all options (but not two-stroke).
How about the YS70S? (If it´s available.)

I am also sitting between the Osmose 70 (or maybe Oxalys 50) and Spot On 50. (I could not find a dealer, neither in UK nor DK who has got the Spot On ready to ship.)
What would be the better choice (not considering money)?
Getting a new plane and new engine anyway, who about looking up to the 90/110 class? I guess the difference is not that big in flight performance.
Cheers,
Michael
