Gremlin motors wont spin up

[mlem567]

Hi I just built my gremlin. I set it up in Betaflight and the motor spin up there. But when I use my DX6e the motors don't spin up. I see the throttle request in betaflight ok. I set aux 1 to arm and tried it with removing aux 1 but still the same the motors dont spin at all. Help please.
Thanks, Mike
