The xray nt1 is by far the best car in terms of fit and finish and parts quality.
I had a vone rrr evo 2 wc last year perfomance wise it is had beat but the parts on the nt1 are alot stronger than the ones on the vonerrr with mugen mtx4 comeing in second after the nt1. I had a mtx4 r 2 years ago so I speak of of experience. My serpent kit that I had last year was missing pArts and thf fuel tanks were no good and you have to modify pArts to get them to fit flush on the 966 and 733 that I had last year so as you can see I am not a fan boy I test most products that hit the market. Xray products are the best made products you can buy on the market but they do come at a price you get what you pay for.
