This is short test flight of Baby AR wing pro that was loaded with 2S5P and was changed motor to 2204.5 kv3500.

3 motors 2203.5 kv3300, 2105 kv3600, 2204.5 kv3500 are similar size ones, but slightly different kv ones.

At this time, for more efficient result, mid kv one was selected.

Of course, for more efficient flight,
the cruise throttle was decreased from 1400 to 1350,
so average speed was slightly decreased,
but, efficiency of flight was slightly improved.

This reduction of throttle use rather than change of motor is probably main cause of improved efficiency.


Baby AR wing pro repeat 3 waypoints flight many times automatically.

This rough efficiency was 84mah/km,
better than previous 94 mah/km

The maximum flying distance of 2S5P, 20500mah could be estimated to about 244km.


Thanks.
