I will later add some gyro and accelerometer support and a little filter to keep it running smooth.
Sending data to the ground is not really an option with MAX7456. Using the audio-channel is a possibility, but as I use Lawmate, I don't really have good audio-channel to use.
Why it is not an option with MAX7456? At the moment I don't see how those two things correlate, I just thought that MAX7456 will offload main processor, so it will be easier to add.
Haven't checked, but I think MAX7456 does not support VBI, so there's no ability to send data through video channel also - and I guess that cheap EasyCap ripoffs will struggle with VBI decoding.
