Ok Dave, i tested your pack some more, and i think it's great. But the LX sounds are still bad IMO.. Please, if you have headphones, listen to the LX4 and LX6 on high revs going full throtlle. There is some repeating sound that is just so anoying and really hurts my ears and my head. Can you please fix that? Other than that, everything is fine so far. MRT sounds great, so does the XRT, FXR and F08...
