The longer the wheel base, the less likely you are to tip when accelerating hard or coming to a hard stop.
However, mecanum is not at all like full blown swerve. The bot tends to drift a little bit as the rollers spin which should help remove some of the problems typically associated with rapid direction changes and tall manipulators. That being said, I still would not change direction at full speed (or even drop those traction wheels) if I had any sort of large mass up top. But knowing what I know about 488 they will have thought that out already (this ain't their first rodeo with mecanums).

Cool system, glad to see someone went with it, hopefully the ability to strafe will be beneficial.
