What kick up plate are you using? 25 or 30 Degrees? I found The 30 degree plate gave me more steering than you can imagine and had to go back to the 25 but I shall be putting the 30 back in and trying to tune round it. to calm it down a little.

I've had the 30 in there from day one lol I've tried turning the expo down on the handset and it's seemed to have dialed out some of the problem.... It's still not turning in as quickly as I would like, but it has stopped the rear end flicking out when I'm half way around a corner....

I think I've cracked it! :) it feels like it can go faster if my nerves can hold out lol
