The Aries parts look just like the plug (good thing too), so the photos on the mold plug page look a lot like this photo taken during the wing tube mount.
The inside is large enough for an IMAC style component layout. Here's two standard sized servos (JR 8417 and Futaba 9202) set inside the fuse in a forward looking angle. There's enough space to mount the elevator and rudder servos on the centerline above the interior pipe tunnel.
I had to overexpose this because black servos don't show up well on black carbon fiber.
Here's an interior shot looking rearward. No formers are needed in this construction, so routing cables and pushrods will be easy.
