I'm using the 1257 for steering in a xray 808,how much is over kill? I used to run the hi-tec mg645's in my ofna lx pro. That was one heavy buggy and I never had trouble with those servo's. Put then in my jammin x-2 and they finally gave it up after 4 years in my xray when I switched to lipo. I had trouble with the sovax servo's got it fixed.
