Agile, high TWR super-heavy SSTO spaceplane.
Rated for 100 ton paylod to Kerbin synchronous orbit (2,863 km). 12m x 3.75m cargo bay capacity.
2017-08-07 : Quick update, added additional RCS ports on the nose for pitch control during reentry, action group 3. Added monopropellant and electric charge. Refitted stabilizers.
Take-off to orbit instructions :
1- Throttle 100%, stage and let the engines spool up to ~250kN
2- Stage, then let the aircraft accelerate all the way to the end of the runway. May not be necessary if payload is light enough.
3- At the end of the runway, pitch up and set attitude to a ~35° climb. Gear up.
4- At engine ionization (700kN thrust/engine), progressively reduce pitch to a level flight. Keep Ap under 27,000m and over 25,000m
5- Gather horizontal speed. Increase altitude as the nose heats up.
6- At 100kN thrust/engine, stage, then progressively pitch up. Do not exceed 20° angle of attack. Use action group 1 to cut off Nebula engines and close intake ports to reduce drag.
7- Past atmospheric height, proceed to desired mission parameters. Turn on fuel cell with action group 10.
Orbital maneuvers notice :
With or without a payload, the craft has an offset thrust. Reaction wheels are enough to keep the craft at any desired vector but will quickly drain batteries ; make sure the fuel cell is running. Turn on RCS before an orbital burn as a precaution, it can be turned off mid-burn. Use SAS-Nodes to stabilize the craft in space.
Reentry procedure :
1- Set Pe to 25,000~28,000m, over the ocean west of the KSC.
2- At 70,000m altitude, orient craft at a 20° angle of attack. Turn on RCS.
3- During reentry, watch SAS control inputs. The craft may flip, so pitch down preemptively. Keep AoA to 20~30° during reentry heating.
4- Apply airbrakes under 800m/s until subsonic flight.
5- If fuel still available, keep airspeed to 200m/s until final approach.
6- At final approach, apply airbrakes, apply throttle to keep at least 75m/s and touchdown.

Do you really want to downvote this?
Don't forget, people build craft at all skill levels, just 'cos something is 'newbish' doesn't mean it needs hatin'.
It will cost you 5 of your own points to downvote
