Review on IFlight Controller BLHeli_S Transmitter Quadcopter by Sarah Pullen

a solid little F4 and ESC with tiny solder pads as you would expect from a 16x16 but it doesn't take much soldering and the pads are adequately spaced. But it's VTX! Wow! I bought it thinking I would definitely replace the VTX with another one with higher output power, but that 200mw outperforms any mini 350mw I'm using. Runs on 3S with no cap and just a small whip antenna and the picture is clean and clear where it snows at higher powers. The documentation says FC can't use Frsky's F-port with telemetry, but everything works fine for me. with inversion modification R-XSR.
