Good info from Jason regarding Thrust Angle. The propeller is not installed perpendicular to the axis of the plane so that it will fly straight to counter the torque generated and the effect of the wing location. Plane with high wing, has the tendency to pitch up. Pointing the propeller a bit downwards will fix this issue. More info in the video. 

The goal here is to minimize the amount of trim you have to put in orrder for the plane to fly straight. If you have installed the properller without the thrust angle, the last resort is trim trim trim.

If your plane has a cowl, usually the manufacturer has positioned the front of the cown with a thrust angle. You can start here and then adjsut accordingly. This part of the build is very fiddly but if you get it right, it will pay off when you fly. The design of the engine mount can make this setup easy if you have the adjsutment points. Some other engine mount cannot be adjusted.

   

   

   

This engine mount is very good
   

Big thanks to Jason.
