DJI S1000, S900 and custom airframe with wookong and A2 need hardware and software customization. The three~some come with the gimbals which also need to work with the Futaba controller (receiver R7008, etc)
I will be using them along with the Futaba T14SG, 8SG on Dji Assitant.
Pixhawk Cube is on a quadcopter airframe, which stopped arming and I don’t have any clue.
My budget: usd 150 with install, customization and documentation
