Did lots of work to my new control box for the Rylo Hero!!
Milled the front half of the side away to allow for the LED plate (although now that I've looked, I'll have to do a new plate, I think this one's a tad thin), resized the triangle LEDs so they weren't quite so large, drilled and tapped holes for the tiny screws and threw it all together.
I think it's looking pretty darn close to the real prop, but still not QUITE there!
