Description

As requested by moonsparkejo: SpaceX Falcon Heavy replica with Elon Musk’s Tesla Roadster as the payload, just like irl! (Challenge: All stock)
This is still a work in progress, as I am still working on the payload. I’m going to update this craft when it is finished, but I might as well post what I have anyway.
Edit: I updated it. You know darn well what’s in the fairing.

Instructions
- I don’t actually know.

I’m sorry, but I was running 3 frames/sec in the damn SPH! Just imagine landing one of these heavy boosters on legs supported only by back-of-the-envelope calculations with ~100-150m drift between frames! Also, all the graphics settings are at the absolute minimum.
TL;DR You’re on your own.

Edit 2: I stress tested the landing legs using only the bottom part, some gravity hacks, and craft file edits. They should work for up to ~ 10 m/s impact. However, I also found that aero forces hinder deployment, so only press ‘G’ when you are traveling slowly. Additionally, beware that the locking mechanism for the legs cuts the engines for some reason, so deploy the gears at high altitude.

Built in the SPH in KSP version 1.3.1.
