both Mediatek "DIYDrones" protocols 1.4/1.6 are implemented for 
Paparazzi and can be used for fixed wing. Not sure that it will work for 
quads as the protocol does e.g. not deliver ECEF. Some values are 
derived as they are missing (e.g. climb rate is calculated from 
consecutive altitude measurements).

The receiver behaved pretty poor in marginal situations. It reported the 
plane had kept flying the same direction/speed/altitude when the plane 
was in fact (intentionally) in a heavy spin and losing altitude. Not 
recommended.
