You may have noticed the T50 has 2 pairs of rotors (not just 1), stacked on top of each other , at the end of each arm.
There is a correct amount of propeller surface area needed , proportionate to the weight of the aircraft , to create sufficient thrust / lift . This can be achieved by adding more rotors (coaxial) or making each rotor larger (regular quad / octocopter ).
Here are some implications of each design:
1. Updraft and drift
The MTOW (max take off weight) for the T50 is 103kg. If the MTOW of another aircraft is higher (let’s say 110kg for instance) , it needs more thrust , which could potentially mean more updraft of spray droplets and may lead to more spray drift.
2.Torsional strain
with coaxial, the rotors spin opposite directions, containing and balancing the torsional strain at each arm.
with a regular quadcopter, the torsional strain goes right through the airframe. so the airframe needs more heavy construction (usually equals more weight) to cope with this.
3. Stability
The coaxial is also more stable and controllable , especially in a gust of wind. This creates much better yaw stability. that’s because the airspeed is much higher going through the coax props than a regular quadcopter.
4. Redundancy and safety
With more rotors, if some of them get damaged , the other ones may be able to still mean the aircraft can come down slowly and in control ( and less likely crash). With only 4 pairs of rotors, if one of them is damaged badly enough, the aircraft will very likely lose control and crash.
