this is just to show you how behind i am with new releases or so i thought i was, LOL.. 4 months ago when i got my spartan i start modding it by replacing the cooling jacket with aluminum and added another set of trim tabs, and i was going to do the individual cooling line but never got around with it cause i stop playing with it. then i saw someone did replace the drive strut bushing with a bearing and i thought that is a cool mod. now traxxas have release drive strut with bearing now? did this came out when they have the new spartan with TQi RX/TX?
