Ideally, airspeed from a pitot source would be way better than GPS for understanding the aircraft's handling. Pitot airspeed is what could tell us what's happening with the air molecules across the wing creating lift (or not!). I think that's why Sid asked.
Some ECUs have limiters using pitot airspeed correct? Can we get that info in telemetry with systems on the market? While were at it, can I have AOA too? If I say please?
The Spektrum telemetry system has pitot airspeed as does the Eagletree. I haven't looked up much detail on the Futaba system, but I'd be surprised if it didn't have an option for pitot airspeed - its a cheap sensor.
AOA is much harder - the sensors are *much* more expensive and too big to be used on a typical model - although they can be mounted on one, they don't look very good!
