The BrainFPV RADIX LI 20mm x 20mm flight controller
- Compared to the RADIX, the RADIX LI:
- SMALLER (duh): 20mm hole spacing, 26.5mm x 26.5mm outside dimensions
- HAS 5V REGULATOR
- Can be powered directly from a 3S - 6S LiPo battery (500mA BEC built-in)
- NO BARO
- You can attach a GPS to it if you want to know how high you are
- NO MICRO SD SLOT
- Who needs blackbox if you can use the custom BrainFPV OSD spectrograph for tuning?
- NO ANALOG RSSI INPUT
- Using RSSI or LQ over an RC channel is more common and more accurate anyways.
- SO RIDICULOUSLY CUTE
- It is just cuter. Nothing more to say.
- RADIX LI flight controller
- Silicone anti-vibration grommets 4x
- BrainFPV 4-in-1 ESC cable kit (cables and connectors to make a cable that works with any 4-in-1 ESC with a JST-SH 7 pin, 8 pin, or 10 pin connector)
