no not all updates are nesecary on the KT the only one i did is the <u>schumo Idler tensioner </u>installed, the plastic tracks are of good quality but just like the real one rocks (gravel) is a enemy, even on metal tracks you have to take care when turn in it. My four kt's were from 12 to 7 years old just fixed the idler tension, i ride everywere ... yard, woods and sand and gravel, concreet just everywere no big problems at all.
That tamiya stuff is realy very sturdy when use it for what its intended, No King Tiger model rides 30km/hour if even the big one drove at max 36km on good ways and in the field hardly 17km, thus our models has to be slower 6 &agrave; 7 km is a good speed this are not ferrari's you know

I would say , yes proper build and battledamaged <u>the King Tiger from tamiya is a realbrutal beast</u>almost unstopable frontal unpenetrateble that should be with the battle units also, it could shoot at 3km an allied tank.
Those battle units suck even a pzkfw III can knock out a beasty KT THATS not real, yes it has to be fun but not childsplay like now ... that's why we at smaz don't battle with IR, we are searching to use blind spots like KTand Jagdtiger at front not penetrateble and even at site the allies tanks has to come within 800m range to had a chance to shot them.
It has to be realer then its fun now its is just fooling around, that was not intended on a 600&euro; tamiya, we want real results ....

We did it at our jagdpanther from HL we mobbed the battle unit at front so it will be hard to knock him out with 75mm sherman even at 500m it was hard in real battles, in real they just bounced off rarely took hits at front, it more fun those ways, the others know the jagdpanther can't knocked out at front so they have to use tacktics to get him down , just as in real battles were doing
