I once owned a Terrascorcher and raced at the Tamiya challenge championship in Cambridgeshire in the late 80's(those were the days). The terrascorcher was completely ballraced and came with front UJ's and of course the front upright suspension as standard.
Talking about Speedmaster Speedcontrollers, I still use mine (the new generation). I am currently running a X500 no limit speedcontroller in my Losi XXXCR and a slightly older Vega 3 in my Fireblade. Great speedcontrollers and completely bullet proof.
