And no, embedded antenna is not a good idea, maybe for park fliers. But is off-topic here to start some antenna basics.
I had been wondering whether anyone had done any tests to determine whether there was any significant difference in performance among the various antenna arrangements: out the top of the transmitter, on the back pointing up (or at 45 degrees), or on the back pointing sideways or even down. Also, does the metal handle get in the way?

My preferred arrangement is that used by the newer Spektrum modules, which provide full interchangeability but raise the antenna above the top of the transmitter and handle. But maybe it doesn't really matter. I just know that I haven't seen any practical difference among the arrangements I've used (most of the above).
