The T40 is a coaxial quadcopter - it has 8 x pairs of propellers (rotors) in total - 2 pairs stacked at the end of each of the 4 arms. Coaxial rotors means stacked on concentric shafts, with the same axis of rotation, but turning in opposite directions. Important to note DFH sells them as a pair (2 pieces per pair).

This is a genuine DJI part, not a third-party part. Please note that third-party parts may void the warranty of your drone and are made from unknown designs and materials. This can change the behavior of your drone, cause it to crash, and or endanger people.
DJI T100 Clear for Takeoff
CASA has approved the T100 for operation in Australia under the Medium category, just like the T50 and other spray drones. The liquid tank holds up to 100 L and the spreader handles 100 kg. There are no built-in take-off limits or system restrictions in the drone or software. You’ll only see a brief notice on the remote screen if you exceed the MTOW, which disappears automatically. To stay within CASA’s operating guidelines, keep total load to 75 L or kg.
