Hi, Just wondering if the RC that came with my Spark will work with the MavPro and/or the MavAir using the Go4 app?

nope.
it's only for the Spark

I was also wondering this

Sad to find out that it can't work

The Spark RC, as the name suggests, only works with the Spark. Hope it helps.

thanks beast...

Sorry to tell you that RC of spark does not support Mavic Pro. Thanks for your support.

Thanks again...

I wanted a Mavic Pro controller for a spark but they aren’t compatible. There are a couple of videos on YouTube about it.
