The MIP Cvd's for XX-T fit on the electric evader ST so the ones for the XX-NT should fit the Nitro evader ST, you might want to check first though as I'm not positive on the compatibility.

What's happening to your stock ones? When I had my Evaders (I had two electric evader ST's and one nitro evader BX) I didn't have any problems with the stock CVD's.
