Used to own #339, never had any probs with the cvds or axles. Only broke 1 arm and that was from hitting the wall at wot. Broke 2 tranny output shafts that was pretty lame if you ask me. I ended up selling it and got a revo. Have yet to break one thing and has won more races than my LST ever did. I liked the LST but I just think its too brittle and always have to be careful not to break anything.
My revo I just beat the snot out of it and it keeps chugging away.
