This is bar none the hardest part to model and smooth I've ever done. Lots of odd angles and protrusions yet it needs to be precise because of the outrigged servo mounts. 3 servos mount to this tray at 120 degrees from each other. I'm glad to be past it. Here's a few renders. 751 polys in this part alone. Total polys are at 9,659
The layout won't be final until the end so I haven't thought of layout. I don't see how I would need to remap anything to get a better layout. I would only remap if I changed the geometry itself.
