I saw an image today and I got me thinking about a deal of this with the FM of the viggen.
As most viggen enjoyers and players know, post nerf, the viggen models have been very sluggish and drop speed extremely fast, leading to wing stalling at low altitudes. This may image may not mean much to some people, but it greatly does to others, the aircraft’s Center of Mass, or Center of Gravity.
As seen in the photo the Viggen is covered in snow, which has added enough weight behind the rear landing gear truck to cause it to tip backwards, lifting a tow hook as well. This indicates it has a very rearward Center of Mass, meaning it should have a much faster turn rate, or at a minimum, a high instantaneous turn rate.
Not to mention the empty weight of the Viggen is 20k lbs, the engine (RM8B) after burning produces 28k lbs of thrust, a positive TWR, meaning in a High G, instantaneous turn, while it will lose forward speed in a directional turn (90° to the left or right) due to air resistance, it should very quickly regain this speed, even accounting for fuel and weapon mass, at the “bare minimum” it stays below the total TWR of the aircraft.
Does anyone else have any idea if the CoM was accounted for in the last FM update made by a third party source, or if it should be reported?

Viggens flight model turn rate charts are public. The latest nerf was made with this source.
Gaijin doesn’t model drag/SEP well though. Also I was not able to hit it’s stat-card top-speed since FM change
Yes, of which I have these, but it still feels very wrong. If CoM was not accounted for in the FM, than it could greatly change its effectiveness.
Really wanted to fly it since Sweden TT was added, and slowly going towards it. But it would be nice if it’s FM will be reworked in a good way.
Well, since apparently all FM’s are “overperforming” there’s a good chance it gets rebalanced, as of right now the only viable Viggs are the AJ and AJS.
So either they will fix all FM’s or revert the Viggen.
I mean, most planes irl dont go above 8g’s and yet you can easily see 13g’s in game lol. But the Swedish fm seem completely gimped to me, the drakens have been given stabilisers for the newbies playing it which has made it that much harder to fly, along with the move up i think ill have to wait another year to grind Sweden sadly.
Yeah, when I dogfight in any of those planes in sim I switch it to Full-real>SAS off, it’s the only way to dogfight at all, and even then you bleed speed and stall so quickly you might as well haven’t done anything in the first place.
Swedish planes have been well known to be more capable than their set G-limiter, by enough to rip half of the flaps off. The entire reason the handbook they used said such low G’s, and that’s because that’s the max allowed G on the “peacetime G limiter”
It used to be 7 before the 80’s I believe, but was lowered to 6 later.
Never understood gaijins precedent. Some jets/tanks youll see them pulling manoeuvres that irl would have caused them to explode. But then the next moment you’ll see a jet that has an artificial g limit on it because the manual said so? They need to decided weather or not they’ll take the best of what the vehicle can do or the safe limit…

Oh forgot to mention, in the Viggen cockpit, the Max G-limit on the indicator is 30 😊
