Mate is on his 4th one now!
they are Good out the box (especially the 1900s)
Lift off oversteer is a killer on them cos they so short!!
Watch out for electrical probelms on them (terrible for it)
Also, Rear beam bushes let go and the wheels tend to sit at funny angles
when that happens.
when they are right, they are pretty solid (if a bit rattely)
little cars!
the one me and my mate have done is a bit different now though
202bhp goes nice now for his track car!
