You did the same mistake that I did.. I just bought the RTR because it came with everything I think I wanted.. But now that I got into racing I realized I should've just got the FT.. That is why in like a month or tow I'm going to buy the World Car..
Umm I know one thing that I realized (driving others) is how big of a differnece that 8+mm chassis did.. Then the 30degree hubs up front (changes the whole car if you ask me) then I heard 0 hubs in the back makes the car a whole different car but dont take that word from me.
