I would like to fly my mavic in manual mode but after looking into a little I can't seem to find out how and even found that this might not be an option... Does anyone know how to/if this can be done?
What do you mean by manual mode?
Every flight is fully manual unless you use one of the automated flight modes.
If you are talking about switching off the altitude and position stabilization (aka ATTI mode): not possible with the Mavic
