<DIV><FONT face=Arial>I can't really offer more than what has already been said
by others, but just thought I would offer my experience on YS63s in
general. On slow flying 3D planes with fat wings I use either a 12x4W or
13x4W on my YS63. The 13x4W is a touch too much prop for it, and the 12x4W
is too little. The 12 revs high and makes lots of noise and reacts
extremely fast (great for vertical hovering near the ground), and the 13 is much
quieter and has a touch more flat-out power, but reacts slower.</FONT></DIV>

<DIV>Hi All, I have a YS 63 FZ. I have run 3 gals. of YS 20-20
fuel through it using a 12x6 APC prop. The best RPM I can get is
7,900. Is this normal or should I be getting more
RPMs. Any suggestions? Thank you. Harry
