I'm not the first to strap rockets to a King Crab, the Rowdy Ranger uses 3xRL10. However the King of Crabs deserves the best rocket launchers available! The RL20s pair so well with UAC20s. Sometimes you gotta wait for the brawl to begin. To pass the time I just play peek a boo with the lasers.
Ok third time's a charm. After more field testing I realised it was running too hot. So I downgraded the energy weapons, upgraded to the LE350 engine and I'm feeling pretty good about this build.
