you name the brand and i have broken it the one thing i love about the volcano s 30 is parts are cheap i rippesd the front end off it and it cost $20 .00 to fix broke the same parts om my savage and was out $50.00 i dont care what brand of truck you have if its not put together right it will eat parts my GF got me my Volcano last christmas cause it was all she could aford and i like it alot havent had any problems with reliability the one thing i will note however if you look at the manual the pic of the carb is wrong they have the high speed neadle and low speed neadle marked backward high speed neadle is suposed to be the one where the fuel line goes into the carb (this may be cause of some of your tuning problems ) one you get it sorted out it is a fun truck as for parts get extra break disk and a spur gear clutch parts and upgrade the shocks same parts are needed for the tmaxdepend on how much you abuse the truck
