Best of the 3.5s and If you’re lucky enough to get this quad and you get Elrs with it, make sure the antenna it’s shipped with is white for 2.4ghz (if you’re running 2.4ghz) and not blue for 915ghz like mine. Huge difference
very good HD digital freestyle quad, only 134g and with a 750mah Tattu R-Line 4S Lipo less 240g.
good speed with 1404 motors and 20A ESC's. I switched to BlueJay 0.14 24kHz ESC Firmware to get bidirectional DSHOT. Now I'm using RPM filter with Betaflight. Caddx Polar is current the best digital HD camera on market. Check my review - https://youtu.be/oH059W3wRKk
