RE: CEN STOCK RX?TX issues
The Skyion is an AM radio. You could have been getting interferance from something. It could also be the batteries that you are using for your RX. If those are rechargable you are not getting the same voltage as you would with regular AA's. If you are running a failsafe the lower voltage could also be causing it to act up.
If you still have the JR I recomend getting another RX and use the JR radio. It will be a whole lot better than the Skyion radio.
