Since KSP v1.1, Squad decided to ‘fix’ the attachment rules of Mk2 fuselages. This has led to some unexpected/inconsistent/buggy behaviour when rotating Mk2 fuel parts, so you may find that some of these parts are flipped over (aesthetics issue only). If this bugs you, please upvote the issue on the bug tracker and message Squad about a fix :). There’s a topic about it on the forums here, PM me if you want the pre 1.1 part config files.

The OSP-33 AeroSol is a VTHL heavy transport SSTO spaceplane. With its novel Laminar Inline Nozzle Engine Array Ramp aerospike system, the AeroSol can deliver an orange tank (36t) to a 100x100 km LKO with ~80 m/s delta-v left. Based on Lockheed Martin’s VentureStar proposal, this vanilla spaceplane has a crew of 3 and practically flies itself to low Kerbin orbit. Just press a couple of buttons, sit back, relax and enjoy the flight (check out the ascent profile below). The AeroSol can also return 36t cargo from orbit, just make sure to drain any excess fuel (the drain valves are located just in front of the slanted tail wings). Built in KSP 1.10.0 by Yakuzi.
NB: RCS thrusters are located inside cargo bay, open to use.

Action groups
[5] Toggle air brakes
[0] Toggle cargo bay

Ascent profile
1. DON’T touch flight controls!* Press [Z], [T], then [SPACE]
2. At 100 m/s, set SAS to PROGRADE
3. Burn to desired apoapsis (100 km max)
4. Circularise at ~apoapsis
*Unless when RUDding or during other loss of control quagmires

Descent profile
1. Burn retrograde until periapsis of ~40 km
2. Level wings and set SAS to PROGRADE
3. At 70 km, set SAS to STABILITY ASSIST, keep attitude between 25 to 80 degrees. The craft adopts a 40 degree gliding angle naturally in the upper atmosphere
4. Under 800 m/s, return to prograde and adopt a glide angle of 0 to -15 degrees. DO NOT deviate too much from the prograde vector
5. Approach runway at a steep angle of at least -15 degrees, flare and touch down

Please remember to keep your arms and legs inside the vehicle at all times and enjoy your flight!
