By mikes14/04/2016Using 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
By Toots21/07/2015Works GREAT! with my new FS-i6. Great to have the expanded range and two way communication. Thanks Bangood And FlySky!
