Tengyun Spaceplane

A two-stage-to-orbit (TSTO) space plane inspired by China's Tengyun project. 1st Stage for accelerating inside atmosphere, 2nd stage for entering orbit. Both stages can be recycled; DV 5.5~6k.

1. Engine
2. Atomic engine
3. Switch mode
4. Solar Panel
5. Ladder and cargo
6. Decouple
8. Sub-parachute
9. Main-parachute
0. cut parachute

How to fly: pitch 10 degree until 1.5km/s -> atomic engine on -> decouple -> RAPIER switch mode and enter orbit (2nd stage)

PS:
i) Unfortunately we cannot control two crafts at the same time. So 1st stage goes boom(or gets deleted?) before we finish accelerating 2nd stage. But we can take more oxidizer and decouple above atmosphere. Then we hopefully have time to fly them separately.
ii) Need to open fuel tanks on 2nd stage before decouple.
