After many hours of work i have finished everything but the weapons* on my Geno Breaker model, i can't believe how well it works, i can barely get HG Gunpla to stand and hold a gun but this model is both easy to get where i want it without exploding AND it only took me like a minute to shift between upright and firing modes.
(*except the charged particle cannon i guess because that's literally the whole body - the barrel's in the mouth, the ports and fins on the tail are particle accumulators and heat vents, the feet shift to anchor it and there's additional vents above the heel, and... well in typical T-Rex fashion the arms dont do anything)
