I have a 360 with an angle valve motor. XP-400SRE 250 hours on this engine now. I would like to eliminate the amount of rudder required to keep the plane square. (ball in the cage) I have good reason to suspect the engine has been installed with too much yaw.
I have the engine level to the airframe in pitch. The manual calls for 1.5 degrees to the right in regards to yaw. (if I remember correctly) I assume this was built in to the engine mount.
In order for me to get the engine level at 0, and straight in yaw, it would take about a half inch of washers on lower right rubber engine mount, and one quarter inch of washers on the upper right mount.
