2500mW high power, stable work, suitable for long range flight. non-interference pull distance test is about 10KM. Six power levels can be adjusted PitMode/25mW/200mW/600mW/1600mW/2500mW. A good two-layer board heat dissipation structure separates the power BEC and the main control, reducing interference and shielding interference. Temperature control protection function to prevent high temperature burning. Wide voltage input, support 7-36V voltage input. It has 3 regional frequency groups to meet the needs of regions. Image transmission control protocol Tramp, support OSD parameter adjustment. The on-board microphone of the image transmission, the sound of the aircraft is transmitted to the ground in real time. Two function buttons, three indicator lights, easy to operate. Mounting holes support 30.5mmx 30.5mm.
