I looks like you are there. It would be very difficult to get the engine out of alignment with the way dave Platt designed it's construction. Wouldn's the camera have to be perfectly square to the model to use a photo to find a misalignment using the edge of the photo ( edge of computer screen ) ? If the camera was even slightly off the engine would appear misaligned even if it is not. Measure on he model and call that correct. Have a great test flight ! It looks and sounds good to go.
