Lipos = ideal birthday or xmas present, so wont cost you a penny...
I remember quite a while back when the original centerdiff conversion prototypes for the Gorillamaxx chassis' were being made, that there was talk of having the centerdiff mated directly to the front or rear diff just like how you've done it Candyman. Does make for a very tidy drive line, altough I forsee a custom length center dogbone being needed to take drive to the front wheels. Plan for that is..?
