When the gryobalance shafts start to thrum, you know you have an imbalance with the impellors that needs to be addressed or it will tear itself up at high RPM's. Wish those hoverbikes had easier access for maintenance. They look good, but everything is buried inside.

This kangaroo rat is hoping she won't have to set the bike down on a stand and can just adjust the bias balance synch screws.
