You can use structural pylons because they can rotate if you put enough force into it. Ask this guy: http://forum.kerbalspaceprogram.com/member.php/20811-VincentLaw He can explain it better than me.
Thanks. The engines are attached to two cubic struts. _____________________________________________________________________ My Soyuz is base off of the 7K concept: Which was never built.
GusTurbo, can you build the launcher for my Soyuz 7K? I'm too lazy to build it right now. It has a second stage and a fuel tank for the first stage. Download
The part that made me laugh was that you used fuel lines on the SRBs. With your current configuration, you shouldn't need fuel lines at all. One more thing: your landing legs are too short for the engine beneath it.
Here's the .craft file I used part clipping to get the engines on. Here are the timings to jettison engines (MET): 1. 1:10 2. 1:40 -decouple- 3. 3:15 4. 3:45 Press 0 to active the retro rockets on the core booster after you decouple and switch to it. Make sure to do a very good gravity; it can't get to orbit if you don't.
It's a decoupler. Plus, I don't recommend rebuilding it as it is very complicated and requires a very good gravity turn to get to orbit and have enough to deorbit.
