I think he means the roller (or pro kit). The losi is a great car and the mugen is a great car too. At my local track I see more losi's but that does not mean anything. I recently started driving a 2.0 buggy after a year and 1/2 of racing the losi truggys and I love the losi car its fast, handles well and very driver friendly. My first race with the buggy I finished 4th out of 30+ drivers.
