wheels, NV's return to Maine, according to Brad - when I spoke with him - is to tweak each and all parameters they've tested via PC sim so far. You mentioned two of them (compatabiity, volume/distance). I'd imagine speed is in there somewhere also. He also did not limit the returns to Maine for just 2 return visits, contrary to what he told you.) I have a call in for him to clarify this point, since his statement to me was that they'll continue testing until such time as is required to transfer the PC info into the PGFA (hope I got the letters right!) This process takes all of 20 minutes
