For some unknown reason only DJI know, the Multifunctional Backpack designed for the Phantom 4 has been pushed further away from getting shipped to users. The date prior to today was middle of April, it now states MIDDLE OF MAY! What the hell DJI. http://store.dji.com/product/multifunctional-backpack-for-phantom-series
I will reach out to DJI and see if this only applies to new orders or retrospective to pre-orders also.
*@#!ing hell DJI.. Was really looking forward to that this month too.
