Thank you Pe. What is the difference in the Ignitions? The one that I have is Solid Black and it says that it can take a 2 Cell lipo. I have DL's and Zenoahs and they all say 4 cell 4.8 so does that mean that i don't have to use ANY regulator on the battery?? Also what about the silencer system that horizon sells? And one more question, What size battery will I need?? My dls are on 2000 and they last forever and my 2 Zenoahs are on 2600's and they last about 3-4 flights!!![:'(]
