Lifting Body Spacecraft

Just thought I’d show you what I’ve been working on lately:

I was working on another spacecraft, but I didn’t like the design - It was not really that realistic. This one is a “lifting body” spacecraft meaning the body of the spacecraft is in the shape of an airfoil, thereby mostly eliminating the need for wings. I’m hoping to be able to make some sort of scramjet/turbojet hybrid that can change from one to the other at need, but I haven’t figured out exactly how that’ll work (I have a few ideas).

Right now (in my spare time), I’m trying to make the bottom guidance fins in the back fold up on hydraulic hings sort of like how airliner ailerons work to reduce air friction on them during atmospheric reentry.
