hello,
I recently bought a used 9CHP (with the module) from a club member since I needed to move up from my 6EX. Needless to say it is not on the same channel as all my receivers. He said, just swap the crystal in the module to whatever you want and fly. Reading through the directions, it says you absolutely cannot do this. Called the hobby shop and they said, yes, you can do it. Hm. Apparently the FCC has made it illegal to change the channel on your TX unless your a qualified technician. Does anyone have any advice on this and where can I get the x-tal if it is indeed common practice. Thanks.
