Milviz Corsair Rear Ballast Purpose

I put 100 lbs of ballast in the back and it didn’t make a whole lot of difference, if any. The only thing I might not be doing that all the pilots that are not having this problem is, I am not using rudder pedals with toe brakes. I have a Saitek X56 flight system. The rudder is the twisty function on the joystick and I use the trigger for the brakes. Does anyone think having the rudder pedals will make that much difference? Is there anyone in this forum flying the Corsair? If so, how do you get your plane to slow down and stop without tipping over?
