It 'floats' quite a bit; it would be worth asking the opinion of a real-world heli pilot on this (several frequent this list). > 2) If I climb to say 2,000 feet again, then turn the engine off, I > instantly lose control big time, going all over the place, instead of > entering "auto-rotation" (sorry for the French word, don't know how it's > called in English) and let me land smoothly. AFAIK the bo105 doesn't yet have a modelled clutch so when you cut the power, the engine stays connected to the rotor and causes it to slow. > The bo105 looks about the same size/kind of heli as the Bell 206, so I > was expecting the heli in FG to behave in the same way as the Bell 206 > in MS Flight Simulator. > The bo105 is actually quite different to a Bell 206; things such as non-flapping blades on the bo105 give it very different flight characteristics.
