I have heard you need to have them far apart. Yet I have flown my helicopter on 72 for years with the Rx tie wrapped to the top of the ESC. When I switched to 2.4g I put it in the same place, never had an issue. I have run my antenna between the servos, put the Rx on top of, besides, under all of the electronics on board and never had an issue.

So, this is how I do it. You mileage may vary.
