On the TC3 vs XXX-S subject.... both are great cars.... I cant see you regreting a purchase of one or the other..... I am still new to the touring seen as well. I have only owned a HPI Pro2 and my new XXX-S graphite.... I really liked my HPI but I love the Losi... The inclosed single belt system is a great idea... I like the belt drive cars... seams to me a shaft drive would have more rotating mass and more drag but I have not owned a shaft drive car....
