i think for your situation that the aerodynamics of the body and wheels isnt something you should be concerned about yet.

the tc3 is a great rtr, and i am thinking of getting one myself.(that or the ld3). im new to on-road so for learning how to set up on road and get them dialed in the tc3 will be good for that.

if your concerned about those aerodynamics issues, then you will will quickly find out when you go to the track and get beat a lot that aerodynamics shouldnt be your main worries. learning all the basics like tuning suspension and driving skills.

jmo but "yank cars" RULE !!!!!!!
