The GEPRC RAD Mini is a powerful video transmitter for 20x20mm stacks. It can therefore be used in a wide range of drones, but it is most suitable for classic 5" freestyle copters or smaller long-range copters. The video transmitter is covered by a cooler, which also protects sensitive components from dirt. The video transmitter has an integrated microphone. The connection pads are handy cameras that make it easy to connect and still allow you to use the OSD from the FC.The video transmitter can be set with a button or via the FC via the IRC Tramp protocol.The mounting holes on the video transmitter are 20x20mm pitch and M2 thread in the heatsink.
