i was reading some of the other post here and i noticed that a lot of the redcat family are very unhappy .Is this only about the spur gear or is there other issues that me and a lot of other folks don't know about? because i am still trying to decide between the advlanghe and the savage 4.6 .i know things come up ,but i don't want a lot of bull with the advalanghe if i go that way ,is the spur gear problem being taken care of by redcat?
