Development of sim skunk works LOCKHEED TF-FRF-104 G

about paint kit for FRF-104g, maybe this can help you: https://flightsim.to/file/30864/f-104-starfighter-template-white-body-and-pilot-texture

I confirm easter egg is available for the Marketplace version.
On a previous post I have said I have by from simmmarket but it was a mistake, I have by form Microsoft Marketplace. I have tried the easter egg simple HUD, I don’t find it useful. I don’t have tried the gunsight.
I think if you really care about dropping bomba and fire missiles and rockets, it is not this F-104 that you need. But if you enjoy flying this very challenging airplane: fast landing speed, fast climb rate, old shool naviagtion with TACAN, inertial navigator, and Radar: This is a great product. About the radar, after buying from Marketplace, you need to download the .exe. manually.

Hello,
do you remember the ā€œSnakeā€ pattern mentioned in SURE project to make the best supersonic run ?
Assure it get at lest M 1.95 before SLOW goes on.
Take a look at /Docs/Snake_cartoons/WFXD3990.jpeg
/Mario
In brief:

  • always full AB
  • step climb at M 0.85-0.9 until 25 kfeet
  • shallow descent to break transonic and accelerate until SLOW goes on (you should get 17 kfeet) you should get approx M 1.6
  • climb to mantain SLOW until 35/40 kfeet
  • level off and accelerate, you should get > 1.9 pending on air temp before see SLOW again ON

Thanks for clarifying. I am familiar with the routine you outlined, and have used it many times. I suppose I am perhaps incorrectly assuming that a plane capable of Mach 2 should be able to break the sound barrier in level flight as well, especially at higher altitudes, but then again this is a plane from the 50s so maybe I’m expecting too much.

hello,
yep, may be you are demanding too much from a not too much powerfull engine and an aircraft with an high wing load.
It breaks sound barrier in level flight at 35 kfeet or so, but you have to wait a little bit, something like 2 minutes, the remaining minute should be used to get higher mach numbers.

First of all, thanks for the reply PaternalSmile51.

I get what you’re saying about breaking the sound barrier, however the F-104 was a very sleek and aerodynamic aircraft. On top of this, the J79 engine is not that under-powered as you might think. For example the J79 has a thrust with Afterburner (which is what matters when trying to break the sound barrier and flying supersonically) of 17900 lb. A modern F414 engines which equips the Super Hornet (2 engines) and the Gripen E (1 engines) has a thrust with Afterburner of 22000 lb. It’s not that less specially considering that the J79 was developed in the 1950’s and the F414 somewhere between the late 1980’s and early 1990’s and again the F-104 is a ā€œmissile with small wingsā€ and thus with very small drag.
What I’m trying to say is that I have my reservations that it was so hard to break the sound barrier in the F-104 specially clean (without external loadout - weapons or external fuel tanks) like it is with the mod which requires a shallow dive from that 35k altitude which you mentioned in order to get something closer to breaking the sound barrier while ā€œlevelā€.

And I would also like to take the chance to report another issue with the F-104:

  • When I tune a TCAN station the ā€œneedleā€ doesn’t point and follow that station’s direction.
    But when I try the same with Asobo’s Super Hornet and the TACAN works perfectly.
    By the way, I tried this with the TACAN stations in Cold Lake, Aberta, Canada (name: UOD and frequency: 82X) and Comox, BC, Canada (name: UQQ and frequency: 41X).

my speedometer stack at 1.8m lol mean it’s can not show more :slight_smile:

Hello,
may be you are mentioning the J79-19 which equipped the F104 S, the J79-11 on FRF-TF 104 G is rated at 10000 pounds on static MIL and 15800 on full A/B not 17900 as you wrote (page 1-5 of flight manual, stored on Community\simskunkworks-aircraft-frf104g\Docs) , 2100 lbs make a remarkable difference for a 20k pounds aircraft.
As i said our model breaks the sound also on level flight at 35k or above fee, it takes a long time (approx. 2 minutes).
In the real operational use of the aircraft we used almost always the ā€œenergy managementā€ (aka snake pattern) as SURE project always suggest.
About TACAN, yes may be several navaid do not respond since it is used VOR frequency converted in TCN channels,
Our test here on Italy and Germany showed good results.
Better use the INS

Thank you all for the replies! I also received this direct reply from SSW confirming your posts:

Hello,
market place and others have the same version, the only difference is on radar (not working on marketplace, but can [be] easily corrected)

Sorry, no chance in going above M1 in my sim. Neither by waiting al long as you like in level flight above 35k nor (but this may be my fault) with the energy management path.

Thought that this would be appreciated in this thread..

You need to unbind the keybinding in your AMD Adrenaline software. Settings → Hotkeys → Save instant gif → delete

Are you guys going to add a working air to air radar when you relase it on xbox. I would pay more if you could do that

First of all, thanks for the reply!
Yes, you’re correct that I was referring (and wrongly so) to the J79-19 which equips the F-104S instead of the F-104G’s J79-11.
As such, I stand corrected.

So far, the only way that I’ve been able to break the sound barrier with your FRF-104G is exactly to perform a maneuver similar to the ā€œsnake patternā€ that you mentioned (get to high altitude full AB, then shallow dive also full AB until breaking the sound barrier and then regain lost altitude while flying supersonically).

I never been able to break the sound barrier while on level flight at 35k feet or above even when flying in this pattern for 2 or more minutes.

Your INS system is AWESOME and it works like a ā€œcharmā€!
IMO, it’s the best INS system that I ever saw in any PC flight simulator, bar none!
By the way, thanks for your work and this FRF-104G mod.

However, having a fully working TACAN system would be great and a great complement to the FRF-104G for not only any backup situations but for also for those times when a player simply doesn’t want to create a new or edit an INS plan/file.
Moreover, TACAN is now fully implemented with and is a feature of FS2020 so it should be much easier to fix the TACAN issue, no?

By the way, here’s something which I think I forgot to mention earlier and which I hope it may help you:
The FRF-104G seems to track/follow VORTAC stations quite well but not (pure) TACAN station.
For example, in San Diego (California, USA) area there’s a TACAN station named NZY (frequency 117X) which the FRF-104G cannot track and there’s also a VORTAC station named PGY (frequency 111Y) which the FRF-104G can track and follow without any problem!
In Canada, more precisely in Ontario there’s a VORTAC station named YMS (frequency 92X) located at around 40 nautical miles northwest of Toronto which I can track and follow without any problem but I can’t seem to track any (pure) TACAN stations in the area.
So and again, it seems to me that FRF-104G can track VORTAC stations but not TACAN ones.

In case you already fixed this TACAN issue (but still didn’t release the patch/update) please disregard this.

Something that I noticed and have been meaning to ask about regarding this planes behavior in supersonic flight. Once I’m past Mach 1 and the plane starts rapidly accelerating, you eventually get the slow light. At this point I back off the throttle a bit which obviously disengages the AB. What happens at this point is the plane seems to jolt forwards and backwards almost as if it’s losing and regaining power. I can’t recall what the engine gauges are doing as it’s been a while since I flew it, but has anyone else noticed this? I don’t experience this phenomenon with any other supersonic planes in the sim. Thanks!

low speed light warning if i understand right. it’s all about mach seal air. and inlet air sensors found it as low ias. so you don’t need to drop power in that way. it’s do nothing except broke normal engine working at mach speed period. in f-14 you have to be sure your inlet full open at that situation or use them auto mod. mach is speed what you don’t want to mess with. get more or less but not about:) this model is real rocket. you set trim to take off push forward gas and after two blinks of eyes you above 10k afterburner bug of course pull some back and afterburner again kick you again and after four blinks you are in alt when you feel good time to dive and after three blinks you see speedometer 1.8m stack and buffet of overspeed:)

btw. why this strange bug of 10k so longlifer? could it be connected to mentioned higher bug with mixture?

Hello,
instead retard the throttle (AB switch over may occur) gently climb to maintain CIT on the limit edge (SLOW goes off) up to 37K then level off and accelerate again. (aka energy management)
