e-Revo - Search on rc-m and there is confirmation posted by myself from Feigao that they make the motor from Traxxas. Traxxas confirmed it - No harm Feigao are good entry level motors and a S/M can is more than enough for a rustler/pede.
As to the comments by drift_buggy that is sarcasm which American's have a hard time picking up on... Funny for us though - lol...
