Using this on an Eachine 250 Racer with Flysky-i6 transmitter. Range and reliability is extremely good. Price is unbeatable. Two-way data link allows monitoring of Racer battery voltage and low battery alert (using the RC groups mod to monitor external voltage instead of RX voltage - that is the yellow wire emerging from a small notch made in the casing at the joint line in the attached photo). I have tried a Flysky CVT01 voltage measurement module which works well but the Flysky-i6 transmitter does not allow me to set a low voltage alert for the measurement returned by the CVT01 - so the RC groups mod is better in this respect.

great receiver, easily over 1km range with standard hand set. and over 8 channels using ibus. for better weight and size remove the plastic case and cut off the pins, solder instead
