You might want to post a picture, but I wouldn't exactly call a motor a "minor protrusion" allowed by R2--which would mean that you're potentially already over the frame perimeter. If I could see a picture, I could tell pretty quickly where your perimeter is and where you think it is.

The rest of the response will follow shortly, I'm taking some time to get it right.
