Hobbywing made xrotor video transmitter 30505000 (hw-30505000) drone system small size & exquisite design the stm32f405 mcu which features the powerful computing capability and super-high running frequency allows the fc to run the pid and gyro with higher frequency. Voltage-regulating filter, adjustable transmitting power & adjustable voltage for camera the integrated voltage-regulating filter isolates the interference of the power system from the vtx to ensure the image stays clear and stable when the aircraft flies at high speed. The adjustable transmitting power (0/25mw/200mw) and stable output power guarantee long transmission distance. For different applications, the supply voltage for the camera is adjustable between 5v and 12v. 48 adjustable frequencies & race bands supported the 6 frequency groups with 8 channels in each group form 48 frequencies; the frequency distribution is applicable to most receiving equipment. Among the frequency groups, group d and group f are frequency groups for competition; users can use the 8 frequencies in the same group at the same time without worrying about interference. Stack-up installation supported when pairing the vtx with the hobbywing f4 flight controller and xrotor micro 40a 4-in-1 esc, the installation is highly integrated, simple and convenient, and makes the aircraft more applicable to the fpv racing.
