    larrylynx Can you comment on the Lynx susceptibility, or lack thereof, to enter Vortex Ring State (VRS) when descending vertically?

    I've read about this many times, but never noticed it flying Lynx or R22. Recently I tried flying the UH-1 Huey in another simulator and the effect was so prevalent and severe it took practice to avoid. Made me wonder about the Lynx and FS2 simulation of helicopters. I did not notice mention of this topic in your manual.

    Schnuffelduffel I see you made a big post at about the same time as mine, yours appeared first.

    If I had won, I'd want you to keep the money. I made a small donation to you and Higgy. You're not going to get rich giving things away for free!

    But it was at least a couple hours fun hunting for the treasure. Italy is an enormous country when you try to cross it!

    Edit: I think you should pay Firststep the prize, he found the location and made the donation. Seems you keep wanting to update the rules, the prize and the discussion. Time to end this, perhaps your next treasure hunt can have more clearly defined conditions from the start ;)

    Well done Firststep! I am happy for you.

    It was there after all...

    Within a few hours of Schnuffelduffel posting his 3 bright spots hint I located the place and circled around. However I thought I was looking for a bright yellow furry face, not writing in a corn field! I would have felt like a cheat anyway. I used his screen shot to guess the time of day and orientation relative to the mountains. Knowing it wasn't too far south from first hint, I searched ridge lines on the map based on the guessed orientation, and found the location on about the 3rd guess. I also set the time of day to dawn and dusk for some of my circling trying to find high contrast, which was the opposite of what was needed.

    The video, while enthusiastically presented, is simplified to the point of being misleading.

    The main take away is that the Vulkan driver doesn't do as much and instead relies on the application side to prepare resources for rendering. There are also efficiencies by design with the new interface to scale better with more CPUs and more dynamic scenery. Also importantly, the per draw overhead is significantly reduced for large scene / entity count scaling.

    The down side is that the application need perform some of the tasks previously taken care of automatically, so if care is not taken, performance can be worse. To assist with this, example code has been made available.

    As Jet-Pack suggests, an OpenGL application can perform well if it manages resources more carefully even though it may not have as much control. Experienced studios have been doing all the things he categorizes in the Vulcan pattern for the last two decades.

    ..and i have the Problem: I falling through the map, if i try to land ( landscape ) . :(

    I've encountered and reported the same. Larry responded that it's the sim, not the model's collision objects. In the R22, as well as this chopper, I also get my skids stuck in the landing pad causing it to flip over or get stuck.

    larrylynx Do you have any tips relating to visibility and landing?

    I struggle to see through the cockpit toward the landing pad. The lower windows are very small and to the side. I've tried shifting my view up and down, which doesn't help a lot. The 3rd person view is quite helpful, but kind of cheating when trying to get the full sim experience.

    The chase camera, or whatever the 3rd person camera which typically looks at the aircraft from behind, is different with this chopper. The camera faces the aircraft from the front and right.

    This view is normally handy for situational awareness and casual scenic flight. It also allows head tracking to pan, which other views do not.

    Is there anyway to change this?

    The purpose of this guide is to help people who would like to try Larry's Lynx Mk 7 chopper but are intimidated by all the buttons.

    larrylynx Please do not read this article, it will make you cry or rage.

    Our goal is to get the chopper started and flyable with as few steps as possible.

    Once you've achieved that, the mystery and magic is broken, and you should then read the manual cover to cover a few times and follow the startup instructions properly.

    For now, we're in that scene from movie Jumanji, where The Rock is under fire and running toward a chopper he's never flown before. He doesn't care about breaking the machine, and has no time to test the systems first, just jump in and hope fly to safety, I mean crash softly somewhere else.

    The controls we care about are located on the center consoles, mostly ceiling and floor between seats.

    We must prepare these items:

    1. Electricity

    2. Fuel

    3. Engines

    4. AFCS/ASE (can fly without)

    5. TANS/Doppler (can fly without)

    6. Trim (can fly without)


    1. Battery on

    2. All AC and DC on


    1. Up to Manual first

    Wait for blue light above

    Down to Auto

    (Repeat for both sides)

    2. All on except crossfeed


    1. Rotor Break down to off (if not already)

    2. Starter Master on

    (Left side first)

    3. Igniters down to on

    4. Move the throttle cock down a bit (or all the way)

    5. Press the red starter button

    (Repeat for right side, shift camera to see what you're doing)

    6. Set drive from ACC to Main

    7. Speed Select all the way down

    (Move both throttles all the way down)


    At this point you could pull back on the collective and head into the sky.

    However one warning remains on the central warning panel, AFCS.

    AFCS / ASE helps stabilize the chopper, so best continue with the next few steps.


    AFCS / ASE

    1. Turn AFCS panel switch on

    2. Press ASE button (lights up)

    3. Press all these buttons (light up)

    TANS / Doppler

    1. TANS system on (Fail light illuminates)

    2. Doppler On (Fail Light extinguishes)

    3. S/Y Switch (Selects Doppler, nearby light extinguishes)


    1. Position/Demand switch right to Demand

    2. Pitch/Roll switch down to Roll (if not already)

    3. Trim Pitch 2 clicks Backward

    4. Trim Roll 2 clicks Right

    5. Cyclic Trim On (Needed for ASE)

    When configured as described, you will observe calibrated trim on the needle gauge to left, and any trim you supply from the simulation inputs.

    Find the cockpit lights on the bottom left end of the middle console and flashy lights on the top left of the middle console.

    After flying and landing or crashing, go read the manual and try to follow all the startup and shutdown instructions.

    EDIT: Updated and added Trim.

    I'm finding flight into terrain unpredictable...

    A couple of times I've crashed into a mountain, but instead of crashing, merely sunk hundreds of feet underground, then flew my way back up and out.

    A couple of times now, I've prepared for what I thought was a very soft landing on flat ground, quite proud of myself, only to have the aircraft reset as soon as the skids touched the ground.

    I'm guessing this is an FS2 thing rather than the chopper being more or less gracefully about intersecting the terrain?

    Well done Larry Lynx!

    Just concluded my first flight.

    May have skipped some of the TEST steps in startup sequence.

    Does ECL 'retard to ground idle' mean turn the lever almost to lowest setting, or fully to lowest setting?

    The Heading Hold did not appear to take effect for me, or very subtly so. I certainly couldn't take my hand off cyclic. I must not be engaging it correctly.

    Thank you!

    Schnuffelduffel I'm struggling to download these huge files. Have tried FireFox, Internet Explorer and FreeDownloadManager5. I get 8-11GB then file download aborts and won't resume on any of these downloaders, despite all having resume ability. Do you have any suggestions? Would you consider making a larger number of smaller files, perhaps ~5GB each?

    Anyone else experiencing the same?

    TomSimMuc I did exactly that, and repeated the process, but could not consistently crash to isolate the airport.

    I'm guessing the issue must be caused by a combination of airports rather than a single one or more in isolation. (I can however crash consistently with all of them present.)

    While trying to locate the coords for our terrain mesh test yesterday, I had crashes elsewhere as well, so it's unknown how many bad or conflicting airports are in the UK set.

    KJKsimmer Thanks for commenting Kenneth. It is interesting to know you've downloaded the UK set and are not experiencing this. If you wanted to try a specific reproduction test, ensure you have EG86, EGKB, EGLC, EGLD, EGLL, EGTF, EGWU around London and drop your plane via Location around London. If the sim crashes to desktop while trying to load the scene, that's what I see.

    Thanks Thomas.

    Please don't read my desire for higher resolution mesh to be a criticism of your or Michael's excellent work.

    It's due to the beautiful results you've both produced that I'm spoiled for more.

    It's also my love of flying low and slow that pushes all the scenery to the maximum detail available.

    If you ever find freely available data of higher resolution, I'll be cheering further. If not, I'm content and delighted to fly FS2.

    Feel free to drop this topic since we've probably discussed it enough.

    Just for comparison, I fired up Google Earth.

    The location I showed probably looks better in FS2, though the elevation mesh in FS2 looks lower res:

    A little further around the same coast. Google Earth does look a bit nicer, and closer to what I was hoping to explore low and slow in Cessna or R22:
