Updated Radiolink rc8x range test, over 1500' of range..

update v1.3.0 firmware, seems to help with the range . I haven't tested previous to this update but no issue with range on my road. Put the radio in the slash 4x4. #Radiolinkrc8x #poweredbycastle #slash4x4 #topspeedrc #smcracing #fastrc #Skyrcgnss
