ISSUE DESCRIPTION
In the H125 the torque simulation was never great but there seems to be a major issue with it in SU4. After starting a flight, the helicopter lifts off fine. Once established in a hover, setting the skids down causes a dramatic increase in rotor RPM (at times up to 450) and the VEMD going back to the 3 dial display for roughly 40 seconds. Once the rotor RPM falls back down to the normal operating range and enough time has passed, the VEMD returns to the normal FLI torque dial. The torque then sometimes oscillates between 5% and 25% with no collective input at all.
After allowing the indications to return to normal, upon lifting off again the torque indication seems to lag behind the actual collective input. I’m not a pilot so I don’t have first hand experience in the real helicopter, but this lag isn’t present in IRL cockpit videos.
On the second and subsequent touchdowns the helicopter yaws violently to the right, as if the right pedal requirement disappeared suddenly, sometimes causing an even more dramatic spike in RPM, sometimes close to none.
Edit: After investigating the issue further, I think it might be connected to another issue, where the rotor seemingly has infinite inertia. After engine shutdown the rotor takes about 5 minutes to get below 200 RPM, and then RPM stops decreasing altogether and the only way to stop the rotor is by applying rotor brake. Obviously this is unrealistic, it takes the real helicopter about a minute to a minute and a half to go from idle RPM to zero as can be verified from many videos on the internet.
