I got that kit sitting somewhere in the pile, got it from a friend as a present.
Mine has got quiet a bit of warpage, 1 broken leg and the decals are yellowed.
Actually thinking of making a mold of the front body area and redoing it in resin/solid material(Balsafoam for a master) with a scratchbuild cockpit.
Said that I don't think that the kit is worth USD 200+, rather go for the smaller resin Armorcast kit.
I got both the armorcast MadCat and Vulture(damaged during a move) but those kits, IMHO, are superior to the Horizon offering.
Those build into nice models and are still a good size and well detailed as they got quiet a few white metal parts..
Same way that the "BEST" ED-209(OOTB) is the old argonauts kit, of which I unfortunately ended up with a recast(another present) prior to getting the real deal.
