??9920 and plastic center gear??

I was curious about when the BK warrior 9920 controllers would be back in stock cause I know they have been on backorder for quite awhile. Unless I just miss it when they are in.

And I also am looking for a plastic spur gear for my hellfire, it uses a center diff and I am having a hard time finding a gear that I can use with it and my brushless motor.

THanks guys,

BIG D
