Semi-functional SSTO Spaceplane

100% stock parts, no mods, only use of tinkerpanel is to slightly reduce the size of the jet engines.

This is not easy to get into orbit, but it is doable. This craft is not yet fit for re-entry.

Launch instructions (from Droo runway):

1. Throttle 100%
2. Lock current heading
3. Activate stage 1
4. As soon as afterburners kick in activate Rockets AG
5. 60% down the runway pitch up approx 15 degrees.
6. Deactivate landing gear, deactivate Rockets.
7. Fly until 20% jet fuel remainig
8. Smoothly but quickly pitch up to above 45 degrees (pretty much as high as you can go and maintain stability.
9. Activate stage 2
10. Keep pitch just barely above prograde (prograde lock tends to level off to quickly, to steep tends to lose control because of aerodynamics)
11. If autopilot starts to lose stability switch to command chip
    
    
    
    1. Pause
    
    
    2. select command chip, click Take Control
    
    
    3. select command pod, enable replicate commands, replace ALL activation groups, power of command pod
    
    
    4. DON'T FORGET TO THROTTLE UP
    
    
    5. Unpause
    
    
12. Once over 50km AGL disable Jets, and you should be able to lock heading prograde
13. Once apoapsis is approximately 100km cut engines, pause, and setup a planned burn to circularize orbit.

I can get this to 100km orbit with 11% Kerlox and 3% jet fuel remaining. There are major autopilot stability issues when non-atmospheric. Re-entry is a disaster.
