ys fz 63 break in
I am new to the YS engines, I have several Saito's like them very much.
BUT I have two new Ys engines to break in, a fz63s and a fz120.
I want to start with the 63 as I am getting a plane ready for it. Its a funtana S 40 , what prop , fuel etc. I have the instructions , but would look forward to any advice.
