Yes, I am using the #2119 buckup regulator. It produces little lines that travel on the horizontal plane. I needed the extra voltage to get past the bottom threshold of 4.4 volts otherwise my video signal is useless. I have noticed that they now make 1gr cameras that can work in the 3.7v 1s lipo range. I noticed somei nteresting things as I have two transmitters but that will come in another response.
