Only the militarian versions BO105 M-P, especially the armed versions, has a YAW-SAS to keep the helicopter better in place while aiming and shooting. | Only the militarian versions BO105 M-P, especially the armed versions, has a YAW-SAS to keep the helicopter better in place while aiming and shooting. | ||
The 45% back cyclic is completly true and realistic on the BO105 and real values. The rigging of the controls of real helicopters are mostly not symmetrical like the joysticks we use. So the problem is on the hadware side, since realistic and affordable helicopter sim controls are rare. Especially the ForceTrimSystem can't be simulated 100% realistic, and would need corresponding hardware for, which does not exist yet. To counteract FGFS comes with a generic AutoTrim-function. It can be implemented to every aircraft (See Generic/Nasal/aircraft.nas). The Bo105 makes use of it by pressing | {{key press|]}} while moving the joystick. It has similar effect for joystick-users like a real AutoTrim/ForceTrim-System. Unfortunately it works on the pedals as well, which is unrealistic. | The 45% back cyclic is completly true and realistic on the BO105 and rae real values, retrieved from two independant sources.

The 5% of the FGUK Version's EC145 is unrealistic btw. This helicopter (EC145 is just a maketing name. The real name is BK117 C2) has the same, but scaled, rotor head and rigging like the BO105. So it should have the same 45% back cyclic like the BO105. According to to Walter Bittners "''Flugmechanik der Hubschrauber''" this is the case. Depending on CoG, loads, and flight states the position of the cyclic will vary a lot anyway, so a 0% cyclic at lift-off would make problems on other flight states like fast cruise. | The 5% of the FGUK Version's EC145 is unrealistic btw.
