I first had a T2R, and it was a great car, but way too sensitive to any slight setup changes. Ended up getting rid of it and got a TA-05, and now it ended up replacing my TRF415. While I cannot beat my 415's lap times, the times are a lot more consistent, and I'd rather run a little less than a second slower if all the times are consistent. I am running on carpet, and while the chassis does have a bit of flex in it, it exhibits little body roll. If Tamiya makes a graphite upper deck for it, it'll run with anything out there on carpet.
