Ae rtr radio problems
 

Hey guys, the rtr radio with my SC10 has started glitching, and range is terrible, any more than 10m and it glitches/ stops responding. The receiver antenna was damaged at the end, so I clipped it off, but it was fine for 3 or 4 packs, ie didn't play up straight away.

Pulled the receiver apart to see if I could replace the antenna, but it looks like a shielded wire, I know back in the day I used to replace the antenna on my fm receivers with no problem, can I do the same here? Or can I get replacement antenna for the receiver?
