Another data point is interesting for calculating the "Kang Efficiency." This is for an F1B:
duration: 3min
motor weight: 30g
surface area (wing and stab): 295si (19 sq. dm)
weight, no motor: 200g
total weight with motor: 230g
This gives a KE of 20.31. The KE would be higher for the 4 min first round FAI duration and even more so for higher fly-off durations (10 minutes gives a KE of 67.7). Note that a 3 minute flight can be done without the help of any thermals.
