"We received the announcement from DJI last night that they are discontinuing the original self tightening propellers and will instead start to include the new Quick Release Propeller and quick release adapter locking hubs with new kits.
We will be shipping to all customers who purchased from us three pairs of the 1345S quick release propellers (3 clockwise and 3 counter-clockwise) and four of the propeller installation kits (locking hubs) to every customer who purchased from us. DJI anticipates these will be shipped to us sometime in mid April so once we receive them we will ship to our customers.
Also, we received notice yesterday that we will be getting a large shipment of the new E800 quick release props and quick release adapters from our original order so any of those with the props and hubs on backorder should ship early next week. I apologize that we can't ship these out as free ones but they are a different part number than the Inspire props and hubs that are shipping from DJI for free to us."
