the pack is as far forwards as is possible, i actully cut the hole further forwards. the weight is in the tiny v shape left and another slab of lead ontop, very ugly. i am slightly heavier than others, but probably because of the weight. overall every airframe is identical. if you meant am i ballanced laterially, i dunno, just checked, slighty heavy on the left wing.
the up tim needed is different for each slope and wind stenght, i normally set mine to very slowly dive at netural to keep the speed up. on a full dive it dosnt tuck in or pull out, it gos where you point it, a feature of most of these wings is when you then pull full up at speed it'll spin because both correx elevons will never do the same thing even if your thumb got it right.
