Hi what site bullet connectors come with this motor?.. and if they are not the 6.5mm are you able to change to them?..
I do believe it does have 6.5mm connectors. To answer your other question, yes, we can change the motor connectors.

Will this motor fit a arrma felony?
While the diameter would be a correct fit, the length of the 4092 could pose a clearance issue. At a length of 92mm, you would need to check the distance between the motor plate and the steering post.

Will this motor work with a 150A esc, Specifically the Hobbywing max8?
Yes it will, it's important you still follow the voltage recommendations and adjust gearing for proper temps but this will work great with the HW ESC.
