I would like to make some additional load and prefer to be in safe zone. Possible I calculate to far in safe zone. But realisticly 2.2-2.5 kg, easy
About 1.4 to 1.7kg (including motor & battery) would be more in-line for a 1.2m sport plane.
Yes, endeed total weight!
For small motor a 3 blade prop is very inefficient. Some would use a 3 blade prop when the aircraft is on display, then fly it with a 2 blade prop.

Actually good idea for prop!
