and small size, your quad barely notice it's there. The 25mW - 800mW adjustable output power allows you to race with friends and penetrate serious concrete with just a few pushes of a button. MADE TO RACE:Zero interference even while powered up, it's now a possibility! If you've ever repaired a quad during a race, you'll know the frustrations of not being to power on and test your system. With for PitMode, we reduce the output power to a bare minimum (way below single digit mW's), and move to frequencies unused by race organizers, to allow you to power up your quad and still see the image! SMART AUDIO - FULL CONTROL:for SmartAudio technology provides UART and I2C control for your entire video transmitter. Parameters such as output power, bands, channels, and frequency can be freely controlled. for CLEANSWITCH - NEIGHBOR FRIENDLY:for CleanSwitch is a technology developed at TBS that that your video transmitter is interference-free while powering on, or while changing channels. SAY NO! TO DIPSWITCHES:Even though learning binary was a fun mind-game, in practice a single-push-button or OSD-controlled video transmitter is just much easier to operate. Gone are the days of video transmitter cards, stepping on people's channels by mistake, or a mismatch between your goggles and video transmitter frequencies.
