Hi Jimmy,
I am Eric Siow here. My first buggy is Losi 8. To face Pre Femca & Femca, i bought my 2nd buggy, Losi 2.0. It had been improved compare to previous but still some weak area as below:
1) clutch belt - original losi clutch belt is not tough enough, it cannot stand for even 1 race.
2) front shock tower - my front shock tower broke before Femca during practice, i had no choice but to use old Losi 8 shock tower.
3) wing holder - wing holder is not tough enough since 1st Losi, but Losi 2.0 has better quality of wing holder.
Basically, Losi is good, easy handling and tough buggy although it looks soft and thin. So far, i am satisfy with what i have now.
