Does anybody has any idea whether RB shut down their forum or what ?. Been trying since yesterday and the link is always broken.

unfotunetely it has been discontinued. the past couple pages here(rctech)have discussed the fact that the rb forum was one factor into buying rb engines. after rody left the forum closed. hopefully google or this thread can help you.
