Ok, i just finished mines

. It's the metal version, it was a little pain in the ass, that just because to be carefull to dont do any bad things to it. The threading for me was pretty easy to do (my dad had a threading manual set wich i used it) after that i made the steps from the instruction, ofc i fucked up a little the 2mm hole that i made it through the HUU

because i made id a little slant and the screw didnt fit through the hole even if i made a 6mm one (and ofc i didnt notice from the start :lol

. But it wasnt such a big deal because i manage to fix it, to just widen the hole. So after i made all this i used a Bison Epoxy Metal to glue the base (i left it like for 1.5-2 hours), and ofc i still had some isseus because i couldnt make it work, i did try with the HU arm at the top (hop up 0) like i saw in the tutorial but i didnt manage to make it work (donno why maybe i really missed something), so i started to thread the arm down (hop-up at maxim) and the bastard started to work as it should. Well i did test it before mount all on the replica and i test it even after on the replica, and its working just fine. Now is time to enjoy it....i hope
