Hi, we have done some initial investigation but we are not quite there to a perfect setup: http://forum.bitcraze.se/viewtopic.php? ... p=194#p194

I wanted to piggy back on this post. I remember seeing a post about doing fpv flight on a small cheap transmitter

I recall it had perfect clarity sitting there, but vertical lines when throttle engaged.

Basically you could add a filter to connection from the battery to the camera system, this would include an inductor on the positive, rated as much inductance you can find for the size. and an electrolytic capacitor on the positive and negative lines. Rated for a voltage at least twice the battery. That should clean up the dirty feedback from the motors and clear the signal. There's lots of info on it for FPV stuff. I believe it's called an LC filter.

You can essentially get these parts in SMT components to drop the weight.
