Bolt stick? never had that problem.
Max-Flo creeping, It creeped a little when left for a while, but was always ok in games. I was told it was because it was new and would settle down.
Battery connection. I had a problem with the main pcb, sent it to smart parts who told me that it was the battery. Never had a problem with a loose connection.
Sorry bud, i'm sure it'll get sorted. After all it is covered by warrenty
