I liked the way the Cen cups look alot better then the oem Savage cups. I figured I paid for them might as well use them. haha I think there are going to be alot of unhappy Flux owners out there when their diffs start breaking. Did you get this mod from RCbasher?

Or did they steal it from you? Either way it works, I just hope it works all summer long. I plan on doing some 6s neu 1515 1.5d testing this spring just to see how high and far a Savage can jump. My neighbors have a pool.........
