This design is made to fit the Mobula 8 with a DJI O4 lite unit. The DJI O4 unit will bolt to the 25x25mm stack. The canopy will bolt to the outside existing bolt locations. The camera for the O4 will use the supplied cover and screws to install inside the canopy. There is a antenna mount at the top of the canopy for the stock dipole antenna. There is a platform at the rear of the canopy to tape a RX antenna down or even zip tie it if needed. Enjoy!
