You heard thet YS's are not any good? That is BAD INFORMATION ---
YS is the finest 4 cycle engine on the planet, very few argue that fact... And the ones that do apparently cannot tune an engine properly--
I'll have to agree with Razor. The only ones bad mouthing YS are the ones that don't understand them. Had a blast with the Saito 100/UCD.60 combo, but...............upgraded to a YS 110 FZ and never looked back. It will show you the true potential of the UCD. Regardless of engine choice you will enjoy this plane. Good luck, Joe
