have used my 414m2 for almost a year now, right after surikarn won and i haven't had a broken arms or parts except for just losing a kingpin, i run open mod for the whole year and race every weekend and never experience any problems, i can even change motor after a heat for just a minute, that u can't do with the evos.
A Whole summer of racing is just a quarter of a year, do you really own a 414????!!!!!!
Am planning to get a 2nd 414m2, which is a WCR, assembled but not used, hoping for a good price.
Problems here on the evos are the stripping of the small bevel gears, stripped ball diff gears and we found out that its ok if you run stock.
