Please keep the realism!

What I can see from the Moth vid and comparing to prepatch game is that the oscillation speeds were perhaps considerably overdone. The amplitude was perhaps not thaaaat bad. Just look at the rpm gauge where you can see the needle sway during inflight. The gauge can be seen a tiny bit on the left side and there's also the needle. I'd say the needle swayed gently with an amplitude of 2 subscale markings each way which corresponds to an amplitude of 1000 rpms. The frequency was perhaps 1.5 to 2 sec.

Another thing unfortunately going away from realism imho is that post patch there's no more pushing back into the seat under high positive g-loads. Yesterday I did some extensive trials with the spit and how strong I ever pulled on the stick at whatever speed the revi remained where it was. Only when pushing the revi moves in the horizontal axis but not at all when pulling. Ok, perhaps the pushing into the seat was overdone before but this should not result into completely removing it.

+1 for realism.

I haven't tested the sim yet so I'm not even commenting on needles or negative G's. What I can say is that a historically accurate simulator must be as close to reality as is reasonably possible. We can't put GPS in the planes just because somebody who lacks the patience is unable to navigate for example.

Looks great from what i've seen though.

Great Video on the Tiger Moth. Some observations.

Tacho gyrations certainly are wild after start. With Flex/Direct drive tachos I would anticipate some fluctuations on start as the drive "takes up the slack" of going from 0 RPM to whatever the throttle position/ Idle would be. Same goes when rapidly selecting idle. These Tachos tend to exhibit more "bounce" at the lower RPM settings. If the drive cable is frayed and or damaged then fluctuations tend to be more evident. (Source Chief engineer of Flying museum in Aus).

Taxying again bounce is pretty wild in the vid.... no idea why unless terrain is affecting it ?

On Take off the tacho is pretty steady with variations of perhaps +- 50 thats all. these increase a little during acceleration as the RPM increase with increasing IAS, but again pretty small

In the cruise (3:56 in the vid) again very small bounces in the order of +- 50 RPM max.

On Final approach around 600RPM the bounce is again very small+-50 RPM.

So the vid shows wild gyrations on startup but at constant power settings and IAS pretty small variations.

Similar variation is seen in Blenheim MKIV tacho. At idle the tacho "bounce" is around +- 70 RPM but in flight including reasonable large speed excursions during a display RPM variations are only in the order of +-20 RPM. This with Pitch set to coarse. There is some great in cockpit Blenheim IV video in this DVD:

With respect to Merlins (Source: Chief engineer Restoration/Flying museum in Aus). RR Merlins were all Mechanical Direct/Flex drive tachos. Packard Merlins were Electrical.
Again talking to current Spitfire pilot flying RR and Packard Merlins he couldnt see any difference Tacho wise just steady RPM with virtually no bounce.

have a look at the Hurri tach needle in post latest Steam release patch

Yes what about it ? In both the CSU equipped Hurricanes and Spits I see a very subtle hunting of the RPM which is pretty neat imo.

Great vid, and what looks like some solid research a few posts back. So it's looking like the most realistic representation of the tach needles in question would be to tone down the crazy fast vibrations to slower bounces, with small variations in normal straight and level flight, and larger variations with taxiing, turbulence, and rapid power changes. Cool.

yeah... it went from bouncy (pre second Beta patch) with WW open cockpit gauge not bouncing, to not bouncing (post second Beta patch) and now it hunts, along with the WW open cockpit gauge, post Steam release second patch



it also rides now when windmilling the prop - throttle off (though I'm not absolutely sure whether it did before or not)

@ White Owl...

which ever way is accurate to the equipment at the time
