Im selling my built and never used MS I v 3.0, it is modded for spark, but the mod needs to be changed around a bit, there is a thread here that can show you. I built this board the same time that i built magnamx-5's, and he had to do this fix on his to get it to work. Please see my add in the classifieds.
