Was the Axys a Pro X?? if so they are only geared to do about 90ish if it has the 1.75 track, so that woulds explain the out for the hole and then you blowing by. Not knocking your sled obviously, but the Pro S will have longer legs. My 600 Pro S just off of break-in mode hit 90 this weekend, it still had more to go I believe too. I have to say its pretty peppy for a 600, but in repeated races against my nytro it was no contest..
