I believe german dials used phosphorescent paints (not radioactive) instead of radium paint (radioactive). The difference being phosphor paints need to be exposed to light to work. They also can glow when exposed to UV light. The lume on many modern watches use phosphorescence principle. The Seiko automatic watches have pretty bright lume. In fact it doesnt need to be dark to see their glow. If it’s sunny out, all you have to do is walk into a shaded area...it doesnt have to be a dark room.

I remember seeing the rears touching the ground (finally). But, yes the front tire could use some air. It looks like it’s riding on the rim.

And now the tires finally actually touch the ground!!! Hurray! The front tire could use a little air, but it’s nice to see it finally planted.

Noticed black smoke with afterburner too

Flew the F18 and A10 a yesterday and noticed the tracers weren’t showing. Gun fired normally and appeared to hit where expected, but no tracers. Any body else notice this?

And on a related note, as hard as I try, I dont see the actual nosecone move when viewing the plane externally. Is this correct?

I seem to recall figuring out by accident how to turn smoke off. The T key would turn it on, but not off. Then by chance I hit left control+T and it shut off. Not sure if that is how it’s supposed to work by default though.

Agreed! It says a lot that there’s a guy that literally built a whole house-sized simulators around this module. A simulator that includes a real mig 21 as a “peripheral”! That means you guys have done something special. Ninnon’s sound pack have done wonders to the experience, and Im looking forward to the FM tweaks.

Who, me? The original poster described this as a “wobble” and “snap to horizontal” that the OP said felt wrong and scripted. Based on the words used, I am not sure if the OP understood this to simply be a stall. When I flew according to the OPs speeds, I got the same behavior and interpreted it to be an accelerated stall, as opposed to a problem with the FM.

File track attached (it happens at the end of the track). I noticed on this track, that it happens only as the engine spools down completely. Once I dropped the nose and the engine began to windmill, the AoA reading would work. If I pulled up and stopped the engine, then the AoA needle dropped to 0 immediately. Not sure if it's a bug, but I don't recall the previous build showing this behavior. aoa gauge failure.trk

As far as I'm concerned the behavior the OP posted about is what you would call a tip stall, or put another way, one wing stalling slightly earlier than another. I seem to recall the previous FM would break cleanly and straight ahead IRC. The new stalling behavior seems believable to me, but I have no idea if the real Mig21 stalls straight ahead or not.

As the title says, AoA gauge is dead after a flameout. This is new behavior since the most recent update, but I’m not sure if it is accurate.

So apparently I didn’t misremember lol! Some weird stuff going on. On a side note, I love doing space runs up to 100k feet. It always flames out, and Im often out gas, so I usually deadstick it to the nearest airfield. Only recently have I noticed that I slowly lose hyd pressure with the engine off (with corresponding readings on the gauges), causing me to crash as I line up for final. I dont recall losing flight control due to hyd pressure loss when engine is off. Has this been recently implemented? Maybe somehow related to the gear failures?

I think he was responding to me. I thought the gear was pneumatically actuated. But apparently I “misremembered” about not being able to deploy gear without air. It was brakes, not gear. As far as the original poster, I cant think of anything else that makes sense unless some sort of battle damage or complete loss of hyd pressure

Every time I forget to put my gear into neutral after retraction, it will run out of air. When it runs out of air, gear will no longer come down with the gear lever. I was under the impression the system was pneumatic. If not, what causes the gear to stop working when your air gauge reads empty?

Yes, I notice the same thing. At altitude, what appear to be whitecaps that fade in and out, are huge... easily twice the size of the Stennis.

You probably left the gear in the up position during flight, which makes you lose air from the compressed air tanks continuously. You have to make sure to put gear lever in neutral after takeoff to avoid this..

Are you on the release version, or open beta? My AB in the current open beta looks pretty good.

Isn’t This thread regarding what is already in the release version of the Mig21? Why are people saying they are downloading other files?

I took up the mig to check on the accelerated stall characteristics at higher airspeed. Most of the time at speeds above 900 i could not reach 38 degrees AoA and stall before blacking out or bleeding speed low enough, which is what I would have expected. So in my opinion, the acc stall behavior seems realistic on theoretical grounds. In real life, manufacturers guarantee you a maneuvering speed below which an accelerated stall will always happen under high AoA. But if you maneuver above that speed, the wing will continue to fly with as much wing load as you put on it including until the point of complete structural failure (or human failure). Of course, modern fighter jets eliminate structural failure possibility by digitally limiting the amount of AoA/ G’s that you can pull.

Link demonstrating stick position on takeoff roll.

Agreed, the real mig appears to need substantial stick back to get the nose up. There are youtube vids where you can see the pilots pull back and hold the stick about 3/4s back once they start rolling. Then they ease off the stick to control rotation rate as the nose eventually starts to rise. It was possible for me to model that procedure exactly when using the previous FM. In the previous FM I would usually use 3 to 4 sec of back trim, and once off the runway, I would need to maintain some back pressure until it finally flew through the trim speed a good 10 to 15 sec after takeoff, when I could finally relax stick pressure. I flew some more last night, and I think I like the high AoA snap-stall behavior. Qualitatively, it fits with the raw nature of the Mig21. But I have to look closer at AoA readings when it is at higher speed. If there isnt accelerated stall behavior at higher speeds, then it should not be possible to reach the 38 degrees of AoA Lupin was referencing. Because theoretically, wouldn’t 38 degrees define where stalls occur (regardless of speed)? Isnt the point of having the gauge red-zone to warn you of imminent stall?

I have not seen the track yet Lupin, but are you describing an accelerated stall? I’ve noticed a tendency to see the nose drop when yanking and banking at slower speeds (like you indicated) and figured it seemed appropriate accelerated stall behavior, even if it wasnt there before. Ive also noticed the occasional wing drop during stalls, which I dont think was there before, but is a nice believable touch regardless. Whether the real mig actually demonstrates this behavior, I can’t say. That said, this new flight model feels weird. I’m still trying to figure out the best way to describe it. The plane acts sloppily along the longitudinal axis, and tends to have a one-two oscilation after any size pitch input, at any speed. Increasing airspeed doesnt seem to “firm things up” as I would expect higher dynamic pressures would. The rotation behavior is also very different, as if the center of gravity is too far back. Very easy to over-rotate now. I used to rotate with 4 sec of up trim, and now with 0 it’s too much. It also seems to need to lift off at higher speeds if you want a more controlled takeoff. I used to touch down at around 300, but now the sloppiness in pitch makes it too unpredictable. Unfortunately, touching down at higher airspeeds such as 375is causes it to easily jump back in the air. It just has a very different character now. Look at how the g meter moves now in flight in response to control input. Even that seems to reveal a certain softness that wasnt there before. Yes, the mig could feel sloppy before in some slow flight regimes, but now it feels like that during all speeds and loadings. I wish I could put this in a track, but it’s more of a “feel” thing if that makes sense. I will say that I welcome improvements in FM to better simulate the real thing. Having no time in a Mig, the previous flight model was the only thing I could reference. The very different feeling FM we currently have begs the question, was the previous flight model that far off, or is the new FM the one that is “off”
