Currently, helicopter developers are hindered seriously by the lack of a ‘Sprag clutch’.
Current ‘workarounds’ are unsatisfactory. It creates an illusion only.
Which means that helicopter models lack this characteristic to act like a reallife heli.
What is a "sprag clutch’.
A sprag clutch is a one-way It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags or other elements allowing single direction rotation, are used. When the unit rotates in one direction the rollers slip or free-wheel, but when a torque is applied in the opposite direction, the sprags tilt slightly, producing a wedging action and binding because of friction.
Helicopters
A sprag clutch is used in many designs to transfer power from the engine to the main rotor. In the event of an engine failure, the sprag clutch allows the main rotor to continue rotating faster than the engine so that the helicopter can enter autorotation.

In a nutshell.
The engine can power the rotor.
The rotor cannot power the engine.
In the event of an engine or gearbox seizure, the rotor doesn’t seize up as well.
After starting the engine, it is a ‘checklist item’ that is NO-GO if it doesn’t function. Functionality is checked by looking for a needle split, when the throttle is rolled off from 100% towards idle.
On the developers forum, I have made an [IDEAS] thread, so that anyone can ‘vote’ to get Asobo to see the need to fix this issue. It would be appreciated if you took the time to click ‘Vote’. Or reply here to show support for developement.
Thanks
