Whats there to be critical off?
Here's the logic:
1. Our 600 and above sized helis can carry our camera gear and then some. i.e. Weight is not an issue.
2. By using only one power pack (lipo) to power both the main rotor and the tail rotor, you're maximizing the discharge stress on that single power pack - as compared to using two power packs, one for each rotor.
3. Similarly for the motor, using only one motor to power both the main and tail rotors is exponentially more stressful, when compared to sharing the load on to two motors.
4. By having two separate motors, the RPM for both can now be precisely controlled for optimum power utilization. You can't do that with a single motor and single power system - too low head speed and your tail wouldn't have enough torque to hold.
5. When you optimize both main motor and tail motor function, it also means you're reducing loading stress on both. Therefore, lipo last longer as will the motor.
6. No belt or torque tube to sap energy. One less source of vibration.
7. When you reduce loading stress and optimize power utilization, you ultimately reduce vibration (vibration = wasted energy).
8. You can now position the tail rotor anywhere you like.
yada yada yada...
The above does not comply for nitro or gas or turbine powered AP helis.
