FV 107 Scimitar issues

The vehicle seems to have 2 “major” issues currently that I am unable to tell if intentional or not.

edit: deleted this first bit, seems the mobility and speed are now different today to last night and can hit higher speeds fine now (last night it was struggling to go over 55-60kmh)

Secondly, the vehicles turret is full of a FCS which seems to be for a thermal optical system. The thermals are confirmed as being unintentional on the vehicle, but no comment about the FCS and if it is intended to remain. Given it says it has control over firing, it really shouldnt given the RARDEN doesnt really work that way. Similar seems to exist in terms of the battery pack and reloading/aiming.

Also small issue, engine is a jaguar engine but claims to use diesel.

I assume the above is because gaijin got a mixup on stock vs upgraded scimitars IRL, just dont want to see an artificially nerfed Scimitar with parts of it that shouldnt be there yet hampering it if they shouldnt.

I do not have any documentation for “backing up” the RARDENs control system, its just a pretty common thing said, if anyone does, feel free to put up a bug report to have the FCS removed ^^. (given it isnt on Fox, I doubt it is meant to be there)

Below are the turret interior of a demilitarised British FV107 Scimitar.

On the right is the gunner’s position, with an AV No.54 Mk.1 periscope day sight in front of him, and the eyepiece of the L2A1/L3A1 Sight, Periscopic, AV (SPAV), Image Intensification (II) that has been removed below.

image

The light blue box on the right is the turret services control box, and there is a gun selector switch to the right of the day sight.

The green box behind him to the right is actually the tuning unit automatic antenna matching (TUAAM) box for the Clansman radio. The remaining small boxes are interconnecting boxes.

On the left is the commander’s seat, with a No.75 Mk.1 day optic in front of him. On the left are the boxes related to the intercom control, the yellow is Clansman interconnecting box 3-radio (IB3), and the black is the emergency crew control junction box.

It’s possible to fit the Clansman interconnecting box 2-radio (IB2) instead of IB3 box in early FV107 vehicles.

Cheers,

Note in general: I dont mean to like, put IRL stuff on others/the internet, but i am at a point where i might be putting my pet down, I really dont have time to be well, going through documents/research etc to put a report in for gaijin and then have to act further on it etc right now, also not in the headspace.

If others want to do it feel free, but the above info is golden imo, and I thank vickers for posting it ^^

Am i the only one whos noticed that the suspension on the Scimitar seems to be a bit broken?

The tank cannot drive over any significant bumps or obstacles, it just acts like its hitting them and will stop. I think this is an issue with the way the front drive wheel is modelled, so it gets stuck.

Also, the neutral steering barely works at the moment.

From what can understand out from your images, this is what the FCS ingame are in reality.

So most of what is the FCS ingame is in actuality radio control systems that doesn’t have anything to do with the FCS in real life.

There are the two things that are part of the FCS that i am not sure what actually is.

Found an official document where most of the radio control systems were described.

Turns out most of the FCS ingame is radio controls.

Gentleman and a scholar.

And now I have created a report on the “Diesel” engine, in regards to it actually being a petrol engine.

https://community.gaijin.net/issues/p/warthunder/i/6nQrCjrXCnFK

w/r/t whether losing FCS should stop the gun firing. @Gunjob 's Royal Ordnance pamphlet describes operation of the gun.

Stating that it is electrically fired by solenoid under normal operation, with the option of mechanical firing. The manual firing button is highlighted in the diagram.

A more complete description of the gun’s operation can be found in The Machine Gun Vol. 5 by Col. George M. Chinn
Stating

the firing hammer is released from the sear by the gunner operating either the firing button or a solenoid

Scan

As we all know, the Scimitar turret itself is manually cranked. So loss of electrical power has no effect on laying the gun either. It’s not accurate to treat the electrical systems as an FCS.
Gaijin have removed NV modification, so power loss to the L2A1 image intensifier is a non-issue in terms of using the weapon.

The No.52 periscope is a day sight (or No. 54 - I forget which No. is the sight for Scimitar and which one is Scorpion) allowing the gun to be aimed with an etched reticle in daylight. It is an entirely separate device to the L2A1 Image Intensifier. It utilises electrical power for some secondary functions like reticle illumination and washers and wipers for the sight-head glass. Otherwise it is a regular optical device like any periscope. It is not a digital display like those seen on modern AFVs or anything that shuts down and shows a black screen when power is lost.

An assembly mounted on the turret ring between the commander and gunner is the battery charger for Clansman radio, unrelated to the gun control equipment.

Is it just me or are those plates certainly not both he same thickness

Ingame they’re both 41mm, however in the model the bottom one is much thicker. This would make sense as its angled a lot less.

Do we have any diagrams to show the Scimitars actual armour thicknesses?

If you guys need to do the bug report again, try using the Haynes CVRT maunal as a source, plus heres the inside of the Scorpion turret to add more for the Scimitar FCS (Both use the same bassis for the “FCS”)

You have the radio source aswell thats good, just remember to cite that and the source name. They can’t be iffy with this one becasue its readily available on the Gov.UK website.

As mentioned up earlier I already created a new report on it, however there have been no response so far.

But as pointed out in a comment on the report, it should not even have any FCS at all, since the gun can be fired mechanically by a firing button on the back of the breach and the elevation and turret traverse are fully mechanically cranked.
