Since my 1DX2 doesn't have remote unless I fork out big dollars I am wondering if this is a viable option - mount the 600 flash on the camera and use the ST-E3-RT as a remote trigger. I guess the obvious downside is that it's just shutter release. I can purchase a trigger that is useful to me for flash purposes for USD $140 and that's what started this thought process. Anyone using this mode?

Jack, you can have one under $100 and it's really awesome. The range and features are amazing.

For the "normal" iOS you need a different firmware and app - https://dslrdashboard.info/
I know there is some overpriced commercial product that's using the same modem but rebranded.
