  1. I always thought that the landing gear compressed to absorb the downward force of the landing and then was higly damped on the return stroke so as not to bounce you back where you started from. This lot may just as well be a big spring with no damping at all.

    I have great admiration for ED's programmers for their fantastic graphic skills, However, I am starting to think that there is a lack of experience how real aircraft handle in the real world. After all, there are not too many Mosquitos left in the real word for just anybody to fly.  😟

  2. The way I see it is that you can't fix it  with the axis tune settings.

    Because the control has to be inverted, all that happens with the saturation adjustments is that you change the minimum brake setting, and it is the maximum setting that needs to be reduced. 

  3. OK. We had a similar problem with savage brakes on the Mosquito in the early days.

    You can fix it with this mod ...

    Go to

    <Your DCS program location> Mods > aircraft > P-51D > FM > FMOptions.lua

    Reduce the value in line 15. (Use Notepad++)

    I set it to 3000 and can apply full brakes without nosing over. 🙂

    Add me to the count of people who are pi**ed off with this problem.

    I am pi**ed off because:

    1. I spent several days trying to find the problem on my computer. ED couldn't be bothered  to let us know that they knew all about it and were working on a fix.
    2. Mega caused the problem with their update that had no provision to be rolled back if it caused a problem.

    I am not complaining as I can take action that will fix the problem for me and prevent it happening again.

    I have been happily using the Rift-S headset for years but been thinking lately that it was well past time for an upgrade.

    Since there is now another 7 days delay (or maybe more!) and this is more than the delivery time for a new VR headset it is ...

    Goodbye Mega and Hello Pimax !   😀

    Can anyone else keep it on two wheels for a long roll out?

    Yes. Me.

    Since I am arrogant enough to think I know all about how to land a tailwheel aircraft on its main wheels, I reckoned it couldn't be me stuffing up the landing, but must be something wrong with my computer or the program.  :angry:  Therefore I did a clean install of the release version without any mods. (Big pain having to set up all the controls and key-binds again!)

    This made a huge improvement and I now get the same results as the videos above. Still wants to oscillate slightly after touchdown, but the bounce back into the air has gone. The wheels now stay on the runway as they should.

    I'll keep track of any changes as I restore my mods to see if they were the problem.

     

    *** EDIT ***

    I take it all back.

    For some reason the brake calibration for the analog axis set the default off value to 50% brakes on. (I had previously reduced the analog brake to prevent nosing over)

    Removing this brought back the bounce on touchdown. Taxying seemed OK though without the bouncing tailwheel. All this on the Channel map at Manston.

    Bugger!

  6. Thanks Yo-Yo. That's fantastic and exactly what I wanted to see.

    Because I can't do that on my system I am now suspecting I have something screwed up in it somewhere as it was installed a long time ago and had many updates.

    Therefore I'll be doing a complete clean re-install of the program in the hope of getting what you have there.

    Thanks again.

    Curious to see if anyone can reproduce a smooth touchdown like these sequences of KA114.

    No you can't. Unfortunately the Mosquito landing dynamics have been completely unrealistic from day one.

    Even if you can touch down with a sink rate less than one inch per week you will still get a  strong pitch up moment and bounce off the runway.

    IRL with a very small sink rate the drag of the main wheels spinning up will actually produce a small nose down pitch moment that will help stick you on the runway. Otherwise, on touchdown, a small nudge forward on the stick does the job. There is no need for nose down trimming or pitching down to smash onto the runway.

    (In case you think this is BS, I have several thousand hours of flying tailwheel aircraft -from Tiger Moths to DC-3s- so I think I can say I know what wheeler landings should be like.)

    I complained about  the unrealistic landing dynamics years ago.

  8. This might help.

    I am using an old Rift S VR headset and have no problems with looking at stuff on the left wall  of the cockpit.

    Screen_231211_082114.png

    The default VR viewpoint is often not satisfactory but it can easily be adjusted using the  RCTL + RSHFT + Number keys.

    I do it by look down at the seat and adjust  left/right/forward/back until it looks like my bum would be in the correct position'

    Screen_231211_082104.png

    Then look ahead and adjust up/down to set the windscreen wiper on the horizon for a handy 3-point attitude reference for landing.

    Screen_231211_081847.png

    Use Voice Attack to avoid the pain of trying to press keys when in VR. Here is the profile I use to adjust the position and sensitivity. The sensitivity sometimes need to be changed if DCS is working hard doing lots of other things at the time. The verbal command "Move Seat ...."is also completely incorrect  as it has nothing to do with the seat but only the viewpoint.

    I found a problem.  

    If you lose and engine while flying the Mosquito while in auto pilot the "off switch" D  C  D  will not work. Nothing works.  You cannot disengage from the auto pilot.  All you can do is fly in a circle until you run out of fuel. 

     

     

    Confirmed there is a problem here. Although in my case it is only when the right engine is feathered and shut down. Everything works OK when the left engine is feathered. Also everything goes back to normal when the right engine is unfeatheres and running again. Not fixed by restoring fuel cutoff, magnetos or radiator - the engine has to be running again.

  10. Thank you - thank you - thank you!

    We can now move into the navigator's seat and do useful things with the radios..

    We had been asking for this for years, but ED seems not to be bothered about finishing half the essential features on the Mosquito.

    Great work and a thousand thanks.

    EDIT: The mod works perfectly for me. However, pressing keys when in VR is always a pain but this can be avoided if you have Voice Attack.

    Here is my  Voice Attack profile that uses the verbal commands Autopilot set /hold - Level /Orbit /Off that selects the required mode and then resets the VHF radio to default channel 1. (You can modify all of this to suit your own preferences)

    Mosquito Autopilot-Profile.vap

    Now I need to find out how to set the default centered view in VR 90° left when I move into the Nav seat. I can get there eventually with several twists, turns and re-centering, but I would like it as a default option. Any ideas? Maybe there is a way to link VR to a snap view?

    I agree its not easy to trim, and you will be unlikely to ever fully trim it out.

    Not so!  The Mosquito can be trimmed out perfectly.

    There are some very smart people in the DCS community., and they produced a mod way back in the early days to reduce the pitch trim sensitivity.

    If you want a "calmer" elevator trim and you're going to use a joystick for elevator trim, go to file:

    <DCS dir>\Mods\aircraft\MosquitoFBMkVI\Input\MosquitoFBMkVI\joystick\default.lua

    You may now do two things:


    1. Modyfiy the original commands for trim nose up/down, but this, while harmless in itself, will result in double commands shown in orange font in "Controls" window. Nothing will break, but you may not like it.

    Orange font and double entries on the binding list will disapper only if you make identical changes to the same commands in .\keyboard\default.lua file - this is a perfectly valid solution, too.

     

    2. Instead (that's what I chose), you may add the separate "trim slow" commands to the file:

     

    {cockpit_device_id = devices.CONTROLS, down = device_commands.Button_16, up = device_commands.Button_16, value_down = -0.25, value_up = 0.0, name = _("Trim Elevator Nose Up Slow"),   category = _("Flight Control")},
    {cockpit_device_id = devices.CONTROLS, down = device_commands.Button_16, up = device_commands.Button_16, value_down = 0.25,  value_up = 0.0, name = _("Trim Elevator Nose Down Slow"), category = _("Flight Control")},

     

    Now you need to tune the numbers for "value_down" in both of these commands to your liking. The original +-1.0 are very fast, while +-0.25 seem very slow. I've just started testing it, but 0.25 seem to be good for cruise when you want very fine adjustments, so you can let go of the joystick and sip your coffee. However, they may be too slow for quick configuration changes clean/dirty/flaps/no-flaps/etc. I don't know yet.

     

    Of course you can also multiply such pairs of commands (just make sure you give all of them different descriptions like "Trim Elevator Nose Up Slow As Snail" "fast as hell" or whatever). For example you can make one pair extremely slow (fine trimming during cruise) and another fast trim pair.  I, for that matter, have a tendency in warbirds to assign one pair of trim nose up/down commands to TM Warthog CMS hat up/down, and the other pair to the trim hat (where they technically belong). Up till now they've always had the same speed, but nothing prevents me/you to have different trim speeds on either of them. (CMS hat left/right is also great for rudder trim in warbirds, while ailreron trim may stay on the trim hat).

     

    Suit yourself 🙂

    EDIT: Sorry. As for the elevator itself - use as extreme curves as in the Spit. You may start with something as crazy as 30 curvature + sensitivity Y about 70 or so. Then work with these numbers until you're happy with the results.

     

     

    I have the Warthog throttle and joystick setup with elevator trim sensitivity reduced to 1/4 for flight and a with a modifier button on the throttle for full speed elevator trim or aileron trim instead of rudder trim. As I think it is cheating a bit and unrealistic to trim using the hat switch on the stick I also have made trim wheels for all 3 axes. the BU0836A also runs the 2 rpm levers and the brake lever on the stick which is the extra column of key-binds showing.

    Here is a modified default.lua file

    default.lua

    and here is file I use with OVGME to install the mod

    Trim_2speed.zip

    Agree completely!

    Current control theory carries on a lot about PID - the proportional, integral and derivative functions of the error signal that can be used to calculate the feedback value for the input signal so that the output changes rapidly, smoothly and without overshooting the commanded value. Unfortunately we cannot do any of this, but we can adjust the sensitivity of our controllers to match our reaction time. The way to do this is to fly in very close formation to another aircraft and adjust the control sensitivity until you can hold position without any oscillating. If the control sensitivity is too low there will be a lag and you will apply too much correction; conversely, if it is too sensitive you will also get too much correction. In either case you will not be stable and you will be oscillating. Your value will depend on the controller used, but for the Warthog I also use a 30% curve. The Mosquito also needs more right rudder and right aileron trim than the default to be perfectly trimmed.

    And here we are flying hands off (briefly).

    Don't give up on the Mosquito. It is still my favorite aircraft even if it still has a long way to go to reach its full potential.

    Unfortunately, most WWII aircraft are in an abandonware state right now.

    Yes. And for this reason I now will never buy anything from ED in "early access"as it may never be fully completed.

    There was obviously a huge amount of great work done  with the radio setup in the Mosquito. However, all that is basically useless in flight until the module gets some  type of stabilization when you move to the Nav seat.

    I guess ED's business model says that the extra sales would not cover the cost of completing the module, so I won't be waiting for this to happen. Pity.

    For the Spitfire, I wonder if it's possible to raise the texture of the reticle and aiming point of the guns up a bit so that the ring clears the cowling. I know that refraction can't be simulated but I do wonder if that'd be a better solution than having virtually zero sighting view for any deflection.

     

    Move your eye / seat position up a bit with LSHFT+LCTL+NUM8

    From this ...

    To this ...

    The gunsight still points to the same position, but you can see a bit more under the nose.
