I know a few drivers that prefer their TA05 over their 415 msx and their evo4 ms..
Their TA05's have all the hop ups (about $450 counting the car) but they are fast and beating the T2's and RDX's. One of the guys is a really good driver though. If Jason started making a chassis for one I would buy a TA05..
From what I have seen it's a great starter car that can be made very competitive. Cheap entry car (novice class) and as your skills improve(sportsman class) you can hop it up a little bit at a time, You dont have to spend $400 + on just a car to start racing. Buy good electronics and hop it up as you go..
