Been playing KSP lately and running a space plane only campaign. This is my latest ship I've been working on. It's a little difficult to launch, but once its up and is at a decent cruising speed it flies incredibly stable, for what I thought would be a super unstable design. It went through 4 designs so far, and still has some bugs to work out. Considering making another plane just to launch this one like Space Ship one and White Knight one.
