They have had two of mine since September 17. Went back and forth with them the other day. Said they had way to many escs turned in and not enough boards. When the new ones show up they said they would only do one per customer and I would get my other one done eventually.... complete BS. I almost sent all four of mine in because they said two weeks.... I then found out that the ones running on 1S are ok and the upgrade would require a rx pack....
