I got my 920 plus today. Huge FedEx box truck the guy pulls up I notice water running out from under door he lifts door and there is 2 1ft holes in the front right top of roof .thank God my boxes were on top of 2 pallets on the other side of truck.so unboxed noticed st16 in powered on position turned off then back on nothing but black screen so turned off hooked to charger after an hr I powered it back on blue light but nothing else not even a battery charge reading.so after charging 2 hrs turn back on it boots up and fans come on. And now shows battery charging. So far so good .the props look like plastic not carbonfiber
