First, thank you all because it helped a lot! I followed some of your advices and I managed to build a spacecraft that is stable enough. I could follow a conventional trajectory with a gravity turn at 10 000 m and reach LKO! Basically I used a combination of your suggestions : - Less tall rocket - Air brakes at the bottom (these compensate deviation when SAS is on!) - Large wing strakes at the bottom - Limit TWR Good job on that guys! I'll try the other designs that some of you proposed as well Thank you!

Hi everyone! I am trying to launch a spaceplane to low Kerbin orbit using a conventional launcher. The spaceplane is mounted on top of the rocket, where the usual payload would be. This is actually my attempt to recreate ESA's Hermes shuttle : I've successfully built one before the aerodynamic model was patched but now (KSP v1.0.4) I haven't been able to build one that flies without flipping over... I understand that flipping is caused by the CoL being in front of the CoM so the rocket is naturally unstable, but I haven't been able to find a workaround to counter that phenomenon... I tried to attach more fins to the bottom of the rocket or/and add tons of SAS but nothing works. The only way I can reach space is to fly it straight up until it leaves the atmosphere which is of course very inneficient... I don't know if I miss something with the design or if I don't fly it properly. Did anyone succeed with this design in KSP V1? Any advice would be much appreciated Thank you in advance!
