Signal problem

[wilpr]

Hi. I’m a beginner and practicing with a XK 110 and the X6 radio that comes with the RTF option. I’ve been using it for a few months but last week, it began losing signal at very short distance. Charged three batteries, first two flights with first two batteries were good, but on the third battery, it began to loose signal at just 3-4 feet from the radio. Recharged the lipo batteries and verified the radio batteries, all are good but still have the problem. Opened the radio and all cables are properly attached. Change flying location, in case it was signal interference, still have the problem. Any suggestions on what could be the problem? Thanks.

Check the antenna poking out of the K110 circuit board. I've had one break off. I re-soldered it back on and all was good again. It needs to be about 31 mm in length.
