This is a printed template for the Flite Test Tiny Trainer motor pod, and Im sure there are others that use the same pod. If you build one of these planes, you will need extra pods WHEN you crash. Works better than trying to tape the template to the foam board. Doubt print setting make much difference, just sand the edges clean and use it. This adds the slight angle the motor needs just like the paper template. When using an Olfa band razor knife, the template allows for you to stick enough blade out to cut one side of paper, almost down to the other side when removing the two small sections.
