Kenneth Tan - Interesting, I've been using the TA04 (and now the 414M) for one year and haven't stripped the knuckle's yet. Most likely, you misaligned it with hub carrier holes and and stripped it that way. Similar cars like the Pro 2 or Pro 3 have the same problem.
rccarracer - Aren't the stock turnbuckles already titanium? There's really no weight difference between tem and Lunsford.
