Cowl Flap 4 not working

    The issue I'm having is Cowl Flap 4 does not move the Nacelles. I've tried several different keystrokes that all register in the control menu when pushed but does not move the Nacelles. I got it to function once, but it immediately caused the V22 to " collide with an object " and has not worked since.

    1. I'm unable to replicate this issue. Cowl Flap 4 Increase and Cowl Flap 4 decrease has been working consistently for all customers and testers- no issues reported. This is likely just an issue with your controller settings.

      Create a new controller profile for the Osprey, clear all other commands for the two buttons you're going to map. Then map them for cowl flap 4 increase and decrease accordingly.

      The nacelles increase/decrease by roughly 0.1° on each keypress - holding the key would move them at roughly 4-6°/sec.

          well I managed to get the Nacelles rotate, however when I throttle up (nacelles at 90) and assistance set at " True to Life" , throttle starting at 0 and by 25% throttle, it crashes and says it has collided with something. If I start at 50% throttle is allows me to max the engines at 4200 rpm and cannot take off. Ive used 2 different HOTAS ( Thrustmaster HOTAS One and Logitech X56 ) both have the same results. If i set assistance to Easy on all, it starts with the nacelles at 0 degrease and once it takes off, it either spins to the middle of no where or crashes. I followed this video "MV-22B Osprey MSFS | Quick Start Guide" by twotonemurphy and cannot achieve anything beyond colliding with an object before i take flight.

          1. Assists must be set to "true to life" for the aircraft to function correctly. The behavior you see with assists on easy is expected (as this interferes with the custom physics for this aircraft). Flight model must also be set to "Modern". That being said, "crash damage" (under Assistance Options/Failure and Damage) can be deactivated - and I would actually recommend doing so if you have little experience with the aircraft.

            I'm unable to replicate any issue with the aircraft crashing into an invisible object at takeoff, regardless of nacelle angle (nacelles >60 at takeoff). The aircraft takes off as expected, and no collisions occur. This seems to be a one-off issue, likely due to your sim configuration, and we have been unable to replicate the issue.

              Are you taking off from an airport at an altitude greater than 8,000 ft? We are currently addressing a bug regarding limitations of nacelle operations at altitudes greater than 8000ft and this issue may be related to that.

                I was able to replicate the exact same issue you mention here at an airport with an altitude greater than 8000ft. This is a known limitation (see "MV-22B OSPREY - TRACKED BUGS"). Currently being investigated. Please operate the aircraft in VTOL/CONV mode at altitudes under 8000ft - the aircraft must be in APLN mode (nacelles at 0) at any altitude above 8000ft.

                This issue is set to be fixed shortly.

                I do see the same problem during initial startup … and found that I have to first move the throttle (even when the engines are still off) … and then the nacelles angle commands (Cowl 4) will get accepted.

                This feels like some uninitialized variable (throttle set to "nil"?) which prevents the CowL commands from getting processed.

                I use a throttle axis … and it did not matter in which initial position my axis was … I always had to move it just a little … perhaps to get some "real" throttle value into the system.

                    Right, this is in fact a feature, not a bug. Hyd pressure must be at least 3800psi on at least one HYD system for nacelles to move. I believe this is not mentioned in the manual, will add now. It takes a few seconds on startup for HYD pressure to increase. Increasing throttle increases the pressure the pressure faster.
