What version of the XXX-T ? Is it an NT? Drake? Francis? Etc..
That might change a couple of things. Also, RPM has some hopups as well as Team Losi itself. If you are running a XXX-NT then you may want to look into the Adam Drake graphite parts. I 'think' they are compatible.
Glad I asked, I was about to send you wayyyyyyy down the wrong path.
The address for HG, who makes KILLER parts is www.1hg.com . Not sure though what they may have for the XXX-T. I dont have one but I will keep my eyes peeled. When I find something Ill post it. Try throwing this post up in general electric talk and see if you get any hits on it.
