Today was fun - I mounted the RDAC and painted box to the mast of the Gyro. What WASN'T shown in the photos is me taking the Gyro outside so I could raise the mast to make sure that the box placement did not interfere with the folding of the mast, and that I could get to the oil tank lid.
Fortunately, the Builder Gods were with me today! Everything fits perfectly, Even with the box cover on, I can open the oil tank lid to add engine oil for the oil injection.
