Sounds like a bad 4 in 1 controller.
Swap plugs for the Tail Motor and the Main motor and see if the Main motor spins .
If so you have a bad 4 in 1.
There is a Falcon 40 thread Come on over and we can get you flying.
Including a repair person for the 4 in 1 for a lot less than the $40 of a new one.
