Hello Owl, I've build my own space shuttle, based on your design (with the tilting engines en external rocketboosters and some extra fuel tanks). The launch it self goes great, but when I do a re-entry on kerbal, my ship is totaly uncontrolable. Does this has to do with the wings and control surfaces or is this causrf due the tilting engines and other things that I'm not known off. I would realy like your - and others - opinion. Thanks!
