Within 3 to 5 working days a Tamiya King Tiger full option should leap through my front door,or maybe the Cat Flap

Anyway,as soon as it is here i will start a build log.
I plan to run a Spektrum dx6i rc unit with this kit (i think this is ok and will work fine) and i do plan to detail the kit but scratch built items rather than shop bought as it's more fun for me.
I am looking up details of things that need to be replaced on this kit right out the box like idler bars,as i would prefer to fix any known issues with the running of the kit as i build.
I may also add a after market sound system but this will depend on the stock sound from the kit.
If you have any advice on what to look for in the way of parts/mods i would be most grateful.
