Devo 7E Fmode and Hold toggle activate on CX-30S

I'm very new to RC. I only have a CX-10 and CX-30s. I have never owned a remote of any kind. I'm just trying to get good with cheaper models before I invest in an expensive FPV with excellent video quality and flying range. I just wanted one TX to control all of my quads. I moded the nRF24L01 chip/antenna, but I'm stuck not knowing or understanding how to program my Devo 7E. Help please anyone!

Figured it out. Here is Cheerson CX-30S with FPV using HOLD toggle for FPV video record, and FMOD for timer for 6 minutes flight time.
