## Questions & Answers

**Q: I have had two of these. The unshielded antenna portion (clear) literally falls off without touching , engine on. Why is this happening?**
A: This should not be happening. Spektrum's QA has always been hit or miss. I would definitely return them for either a refund or a replacement.

**Q: I got a t-rex 150x dfc set coming and wanting to make sure this is all i should need to fly with my dx6e radio?**
A: maybe not, if it come with the FBL is microbeast then you need a special cable and update the firmware, better option buy the regular DSMX satellite receiver

**Q: How to you connect this to the rx2 on a fc6250hx? the supplied cable is 4 strand and the plug doesn't fit the 3 prog rx2 plug on the 6250**
A: The 4 pins on the SRXL2 would need to be put on to the appropriate 3 pin connector. Flite Test has a video on how to do this for their Aurora 5 flight controller. The video is on you tube, just search for "Aura SRXL2 Setup and SRXL2 Telemetry Tuning".

**Q: How do you know if it works?  No lights come on.**
A: Lights must come on. - blinking . . . before binding. If the plane is upside down, you will not get lights. Level the plane and then red the instructions. Then if nothing happens, its a bad receiver.
