Help DEVO 7 with FPV racer

So recently I decided I wanted to get into FPV drones, I decided to build my first drone because I knew it would give me the experience and knowledge when I need to fix it down the road. I mostly followed this guide with a few changes I decided to make (parts list below):


I only changed 2 things about the build, I decided to get the Runcam split 2 and opted for a controller that I thought would feel better to use, the Walkera Devo 7 with the RX601 receiver.

After building the drone plugged it into the PC and set it up in CleanFlight, everything seemed to be working the channels all respond correctly in CleanFlight but when I unplug the drone from my PC it wont respond to anything, I've searched through countless forum threads and YouTube videos trying to find people who have had the same problem but I cant find a solution, I've also tried setting an arm switch as well as setting a fail-safe switch but nothing I've tried works. Does anyone know how to fix this issue?

Here's the important parts in my parts list:
ESC: Racerstar RS20Ax4
Motors: Racerstar Racing Edition 2205 2300KV 2-4S Brushless Motor
PTB: Matek Systems PDB-XT60
Flight Controller: SP F3 Deluxe Acro 10 DOF for FPV Racing Drone
Walkera DEVO 7 Transmitter
Walkera RX601 Receiver

Are saying the DEVO's sticks 'all respond correctly'?

This is very close to the quad I'm doing soon. I hope you get your issues sorted out and be shure to let us know what happens.

So everything seems to be working fine in cleanflight or betaflight (I've tried both) but I think what's happening is the drone is having a problem arming, I've tried changing the arming angle which is one solution I've seen pop up often but that didn't seem to work

Maybe the esc's are not configured properly. Does the firmware match what is on the top right of the configuration tab. Near failsafe. Eg oneshot125 is default I think.
If everything else is OK then this wrong protocol setting would stop you from flying.

In the receiver tab, have you adjusted all your endpoints to 1000-2000? Also as your ESCs are DShot capable, I'd set your protocol in the configuration tab to DShot 300. This will eliminate the issue of calibration and min throttle.

Thank you for the suggestion, however I had already tried that and for some reason it was not working in cleanflight
