Working outt the difference in Non Screen Controllers

I am not a fan of non screen controllers. Always worried about dropping the phone (it did happen) and do not really have any phones that are good enough to work. As most of our drones have come with a non screen controller and we have just bought the screen controller I realise I have some surplus conttrllers. Just need to know which controller is for which drone. The only one I will want to keep is one compatible with our mini 2. Whilst we have a screen controller, if that fails us we want something to fall back on as they are difficult to get hold of.

On the back we have

3x RC N3

2x C5

Just wondered what the difference was with them and do they control the same drones or not.

Thanks

Your ‘C5’ is RC1

I found this.

Cheers. I was sorting things out for the big meet and since I have had more drones since last one I realised that these non screen controllers are just building up and I just would not use them.
