Yes.
1. I have tested the RX-4/16 with all of my TX;s Profi 16, royal SX 16, cockpit SX9, cockpit 7and with the same results.
2. Tried other power source
3. Tried both Pwm and SRXL output.
4. The first one was returned to our techsupport in Sweden but i have not got any feedback If there was any faults found.
5. I have about 17 RX from the micro 6 to Pro 16 and some wingstabi rx9 all of those used with no problems.
Has someone out there used this RX ?
I am very conserned why I got 2 of those from MPX, not at the same time with same problems.
