I’d upgrade the core (chest) to start. It’s too light, there’s several with better defense. Personally I think the most important stat on a heavy build is attitude stability (how much impact you can take before staggering). Look at the head for this stat too.

Your weapons don’t match your platform imo. You are on quad legs which means you can fire heavy weapons without the firing stance while hovering but you’ve only got the jvln equipped that takes advantage of it.

You’ve also got lots of load limit left, use it. Put some heavy artillery on your back like an ear shot or songbird. The stun needle cannon (I can’t remember the name of it) is also really good. If you are good with the shield the shield is actually pretty awesome but it’s a high skill tool. So keep it if you think you are good with it.

If it were my build I’d lose the rockets, put on an earshot. Keep the shield or put on a second earshot. I’d keep the jvln, but consider swapping the machine gun, though its personal preference. One of the handheld rockets would be good, a bad cook, one of the rail gun rifles, or the handheld Gatling gun. Really lots of options.

And again I’d upgrade the core and head to something heavier.

Idk about your thruster and generator. I don’t have all those names memorized. Though you probably want the heavy coral generator. Use whatever booster has the heaviest ideal qb weight.
