Max, are you sure you're playing the same Wipeout Pulse as I am? In all my times flying Assegai, I have had oversteer issues almost as bad as when I use the FEISAR - it doesn't do a lot of sliding but it definitely overturns into the inside wall quite a bit at low to medium speeds, and around long, slight, sweeping curves.

Then again, I could be talking a bunch of nonsense.
