I use both two and fourstrokes, never can seem to make up my mind which I like the most. After I got really comfortable at hovering I do not need brute power anymore to rocket out of troubble. My last Katana 40 profile had a ASP .61 fs and I could hover it down on the deck till the tank was empty, pullout was slow though
My current katana profile 70 I flew with the YS 110 and then switched to a tuned FX .91 and I enjoy that one as much as the YS 110. What`s best?? I really don`t know
