well i'm not sure if you're talking about the truck or the car, so i'll tell you about both. the losi MLST2 has aluminum shock towers (hot-racing), dynamite control arms ,alloy rear hub carriers, alloy tranny case, alloy spur gear , lock up center spool, alloy c block and steering hub, mip cvds and ball diffs (machined for proper mesh), C4 9400kv brushless motor, dynamite ESC. when i get more cash i am going with the single servo conversion kit from EXOTEK, and thats it so far on that.
the NTC3, well, i aquired it through some head work i did on a buddy of mines S10 pickup. it has been change a lot. i machined my own 4.5mm chassis from t6 6061 aluminum, i also made an aluminum gear cover( not on the vehicle now ), made some engine mounts to accept any big block in this case an HPI S25 with GH head with a port and polish, alloy steering rack, digital bb steering servo( futaba ), rpm ball cups, foam things pivot ball protectors, ofna header pipe, and macs tuned pipe for high speed, aluminum fuel tubing, associated ver2 rear suspension, 80 weight shock oil and 40lbs rate HPI springs, aluminum shocks,traxxas antenna mount, traxxas 6v hump back receiver pack, hpi vintage racing 31mm tires and wheels, TRX rustler fuel tank as the team tanks tend to leak, and one RC ONE air filter. that about wraps it up for that one.
