The Bo105-model has one of the most accurate helicopter-fdm in FGAddon regarding flight handling, based on collected detailed data of the Bo105 from NASA-flight tests, flight manuals, pilots and published scientific data from various sources. Due to its unique flight character, and being a helicopter, there have been some false assumptions about the realism in the past by many users, including its current maintainer.

Though the BO105 was the first helicopter with a rigid rotor head, the civilian version had never been equipped with any flight-control assistance like SAS or autopilot. The only flight-control assistance installed is a force trim system by spring-loading.  Only the military versions BO105 M-P, especially the armed versions, have YAW-SAS to keep the helicopter better in place while aiming and shooting.

What is confusing to many users is, that they have to pull the stick quite back to hover the helicopter. This 45% back cyclic is completly realistic on the BO105 and these are real values, obtained from two independant sources. 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.
