I currently have a pusher F-111 and recently I am having a problem after I had to replace / fix the rear mounted motor. Since I added the motor I am having problems with the trimming of it as now she will fly perfectly flat; however, it tends to turn right. What I would like to know is that I originally set the thrust line as neutral but what way do I set it if the plane flies to the right? I am thinking that I should turn the motor left to try and push the nose left. Because of the rear mounted operation and I am just using a normal prop just turned around.
Hope some one can assist me here.

Use washers or some other form of shim to move the motor around to straighten the thrust line. Now for starters we have to get the terminology correct before we begin. When you say 'turning' right, do you mean the right wing is dropping and turning right? Or do you mean 'turning' right as in yaw effect? If its turning right with yaw, as I was mentioning in the beginning use washers or shims and add it to the right side of the mount to add 'left' thrust to stop the nose from tracking right. It won't take much to adjust, I have just done it by trial and error.
Hope this helps.
