Other than flight time I couldn't find the corresponding values for the
P4P. Indeed, aerodynamics, and efficiency plays here, where the
m2 has advantage.
An interesting parameter to consider: the consumption of the camera and the transmission system! This is of course more, if you are recording 4k60p h264 or 4k30p h265! I suspect both cameras consume the same power (no sensor/electricity breakthrough happened in the past 2 years) or very close. With a bigger battery and the same camera I expect the
P4P has an edge here.
I cant recall exact numbers but I've been testing the camera last weekend, about 10min of mixed stills shooting and video consumed about 5-600mAh (8-10%) battery. Give it 25 minutes, and the
available power for the motors will be around 2500mAh for the
m2 and 4500mAh for the
P4P, which is 80% difference, giving some room to compensate the lesser aerodynamics of the
P4P.
