you could mod any gimbal to work- although any controls with the app interface with be void because it's designed specifically for GOPRO4/3 - it could be a matter of toying with signals to switches but there also could be an identifier for the circuit to work before it even attempts to push a signal out to control the gopro- still waiting on mine- with gimbal to use a different camera all together....
you are mentioning the Tarot 2d gimbal....
