technology and level of detail built into this whoop are astounding! With new "Smart Max" technology, uses the MCU to read the board temperature on the back of the VTX chips and uses PID control to control the output power for the VTX amplifier. If the temperature is low enough, the PID will adjust the output power higher, a maximum of 400Mw, and if the temperature rises, the output power of the VTX is lowered to avoid overheating. With the VTX power, combined with ELRS, this whoop will fly far.
