Futaba 9C Range Problems...
I had EXACTLY the same problem as you have.
New Futaba 9C, glitching like crazy, oh god what on earths going on with my brand new radio that cost a bucket load and shouldn't be doing this blah blah blah.
I played around with the antenna postion and it helped a bit but still big problem.
I was upset and couldn't think of anything else to try when i realised something.
When i changed the crystals to a new pair hey presto!
Reception was as smooth as silk.
