rather than choosing ta04 trf i would rather choose trf 414m that also accepts stick pack and offers a great deal of tuneability. it is a very stable car. losi xxx-s will give you great natural handling from out of the box setting and a sturdy chassis ensures your setting from getting tweaked. also the material is good. as for x ray.....its a great car, very solid and sleek, but is all that tuneability needed for your use.
