RE: YS61RE Classic
The prop used was APC 11x 8, nitro content 20/20, McCoy #9 plug. Essentially, I took exactly what I had in the flight box, what I've been using in the past. The airframe is my trustworthy Summit III. This weekend, I'm really going old school - DW 10 1/2 x 7 3/4 balance prop + engine tach.
