Best 2-stroke '60':
Short stroke - the YS .60FR
Long stroke - the OS .61 RF ABC-P Hanno Special MKI with a Performance Specialties piston and sleeve (I have more than 3500 flights on Hanno Specials;
so I'm a little biased
, but it is my all time favorite engine regardless of displacement).

I know that the OS .61RF/P and the Hanno Specials are top notch engines, but I've always wondered why the YS .61 LS didn't take the number one spot.
