The game engine has limits. The “simple flight model” aka SFM is only supports some animation sources. The Advanced Flight Model aka AFM, supports far more. Therefore some things work in AFM and not SFM etc. The biggest differences are in:
| Issue | Simple Flight Model | Advanced Flight Model |
|---|---|---|
| Rolling Landings | NO | Yes - ensure the wheel brake is off and only touch down ~50kph. You will be able to to taxi the aircraft with gentle pressure on the cyclic. |
| Overspeed | NO | Yes - Over 300Kph the main rotor will become ineffective and either cause damage or lose lift falling out of the sky. |
| Tail Rotor Damage | Yes, only via hit point of impact damage | Yes - Sa with SFM but with the added threat of over torquing the tail rotor by apply too much rudder at high speeds. |
