You know what I'd love to see - and I am not sure how this would be possible, but here goes.
In the Telemetry summaries, you can see things like GPS acquisition and the radio signal strength, etc. What would be absolutely ideal is to know exactly when in the flight these things started to drop.
To give you an example, on a few flights, I have seen the radio signal strength drop into the 'red'. I would love to know exactly when (through linking with the video) this occurred. This could then tell me how the camera and the H were orientated, in relation to my radio and possibly give me some insight into why the radio signal is dropping. Ie, it always drops when the H turns one way or another, etc, etc.
Hope this makes sense.
