RE: Futaba R168DF FM DC Receiver for Q-500?:
I've been using a couple of the 168DF receivers and have had no problems. Since it is the replacement for the 127DF that had the High band/Low band restrictions, and is being switched to in all of the Futaba FM radio packages, I feel sure Futaba fully tested the 168DF receiver.
The only problem that I have had with the 168DF is not getting one when I ordered a 6EXA radio from Tower Hobbies. Even though the radio specs had the 168DF in the title and in the Tech Specs, I received a radio with the old 127DF. I called Tower and they told me that I could ship the whole radio package back if I wanted the 168DF. It would have cost me return shipping and the hassle of a return of a radio package, plus a delay. It really pissed me off that they would not just ship me a 168DF and let me return the 127DF. I have a strong order history with Tower, but I will order far less from them now, even though I will continue to use Hobbico products acquired from other sources.
