hiya,i got my lxx char g today with the 3.0 motor..i noticed the tires are fatter...like having 50`s vs a low profile 40..second..the motor is faster than the microsizer 2.2..microsizer steers sharper..i'm guessing cause of the small tires ..the motor was differcult getting in my microsizer..i had to modify..the heatsink...its much better than the motor works ones at walmart..gonna try the fat tires on the microsizer..overall not a bad 10 dollar car!
