The Morgan's Omega 15% fuel is fine in a Saito, it's my fuel of choice. Plenty of oil, and it's a castor/synthetic blend.

I would avoid the YS 20/20 all synthetic, unless you add 3-4 ounces of castor oil per gallon. Just buying Omege 20% will get the castor oil at no additional cost.

The 13x6 is a fine starter prop, fly with it and see what happens.Want more vertical, go to a 14x4. More speed? Try a 12x8.
