New setup, advice on improving video quality
I have my eHawk 1500 setup for FPV now and am really happy with the handling etc. I am now trying to figure out how to clean up the video. This setup is a first for me in several regards and am not sure the approach to take. For starters, this is the first time I am shooting "through" the prop with video, and the first time I am using a cmos camera. So I think I am experiencing 3 different issues that is visible in this video.
1. cmos "jello"
2. Electrical interference from using one battery for both the motor and tx/cam.
3. Signal dropout
For 1 and 2, you can see at one point (7:15 mark) when I am gliding with power off, the picture is great. Also, for the bad signal dropout, I think that was caused by the orientation of my diversity antennas. I adjusted them for the 2nd flight and it seemed to have helped a lot. The dropout always occurred during a right hand turn. Does it help to have one of the diversity antennas tilted so when the plane banks, it is in phase with that antenna?
As for #2, I am going to try to separate the wires/esc better and try a ferrite ring or 2. What wires benefit best from ferrite rings, the video signal or power wires? FYI, using 1.2ghz.
Thanks for any info.
