That thing is going to be wicked with a ys 110!(BEEF THAT FIREWALL GOOD) I would definately put the 2 degrees to the right to help compensate for all that rotational torque you are going to have. I had a Saito 1.00 on mine with 1 degree right and 1 degree down which is equivelant to 1/16" washer. Since you are wanting 2 degrees to the right you could go with larger diameter 1/8" washers if you are worried about them sinking into the firewall. The smaller 1/16" washers on the back two mounting holes of the engine should be sufficient to get your 1 degree down. 1 degree down is plenty in my opinion, but you will want to make sure you have some down, and that will help in landings as the Plane tends to be a bit of a floater!
