Speaking of hop-ups, I rememeber reading somwhere in this giant scale forum that teh 5B has an aftermarket hop-up to make the 5B 4WD. Is that an actual hop-up? Also, will it fit teh 5T? (I think it should, teh 5T base chassis looks almost identical to the 5B chassis.) If this 4WD hop-up does exist, who makes it and if tehre is a link, can someone link it too?

Alo, is there a thread discussing teh different gas engines? Like Zenoah vs HPI's 23cc fulie? Or any otehr gas engine? If so, can some one be kind enough to link it? I did a search and went back to about 2 months prios (that is all I cared to search, there were like several thousand more threads that do not even pertain wo what I am looking for).
