Double test with both the new Bug and .4b vLSO. I might of missed it Sludge, but do you post a change log? Noticed the change in roll input right off the cat. Autotrim worked great during the stroke, and I was surprised with the additional control input required for my clearing turn, no issue just wasn't ready to "muscle" the bug around in the dirty config. Upper airwork next and noticed more nose movement in roll (just basic aileron rolls). Autotrim disabled? At what airspeed should I starting looking for the roll rate change? I started at 18k, dirty/on speed, and started rolling as I cleaned up and accel'd in burner. Any changes to field t/o trim inputs? I'm still manually holding the stabs up. All flights with real world downloaded.

Long time VRS flyer since FS9, so I somewhat compare the Sludge to that although I realize there are many changes and major code differences between the 2 models. Great feeling to have an OK 3 after 1 hook up pass in the latest Sludge version.

Anything major you need tested?

GOONIE:
Sludge,

I will be in OKC for work this week meeting with FAA, so I will be unable to test fly until I get home Friday. Thanks for the latest update brother!

Usually I post something in here in reference to what I've done, but Ill work on getting one out now that I'm back in town.

This was done to facilitate a "semi-real world" reaction to a full stick deflection, whereas before a low/slow/dirty Hornet would do aileron rolls with no drop in altitude. Now you definately CANNOT fly low/slow/dirty and do a full stick roll. You'll go into the drink. In FSX "control axis" do you have your aileron and elevator responses set full right?

Yes, more movement in the nose in rolls. The reason is not from the autotrim disabling, it occurs because I had to give the Hornet its original CG/weights. I did that to give the Hornet a more realistic PA (powered approach) mode, where the nose and velocity vector rise/fall in unison w/power changes when trimmed... but that in turn makes the Hornet less balanced in ALL flight regimes. Hence, less uniform (unbalanced) aileron rolls.

Actually, I nulled out the FIELD UP trim. How did the CARRIER T/O up elevator work for you? The BaseFCS XML sets T/O UP ELEVATOR in addition to the regular dirty configuration UP trim. This is an FSX workaround that simulates a "hands off" cat shot.  To test, after a standard trap pass, taxi over to the cat and leave the trim as it is... once you hook up the launch bar and arm (tension), go to MAX power (afterburner) to set auto-retract for the launch bar, and throttle back to 80% N2. Dont move the stick, pull up the CHKLST DDI page so you can see trim and elevator position. Now, you'll see UP elevator and UP trim. Launch and dont touch the stick til your velocity vector gets 5 deg nose up. Grab the stick and turn to BRC (ships course) and maintain v/vector at 5 deg and fly the pattern. Tell me your results.

Let me know what you think of BFM (dogfighting) handling at 10k-20k-30k. I used JIMIs afterburner/mach no. tweak to get the Hornet up to speed at altitude, so it would perform better up in those regimes without re-tweaking the whole 1500 series tables in the AIR file.

That's about it. Thanks for the inputs.

Hey,
Sludge :)

Thank you very much for the reply. Thank you for the download works a treat. Just got to get back into the hornet :P
I am a little rusty as usual but with the Lovers of the Sludge Hornet I know i will get the best of help.
ATM . . . . I am not to sure what Trim i should have or Waite of the Aircraft ??? I normal fly on 5.6 as a starter point.


This is my channel I will be uploading more when i get it right :) Thanks for the support guys.

Thanks for the good words. I set a minimum of 5.0 on the trim but if you are at MAX TRAP fuel (approx. 8.5) you should start around 7.0 on the up trim and work from there.

Since we cant "trim to feel" like real world, the best way to get an FSX "feel" is to practice getting on-speed to where the W is close to the 5 deg up and the v/vector is about 3-4 deg down, then trim to where the aircraft will hold glideslope and on-speed (amber donut, "e-bracket" centered on the v/vector) with a steady throttle setting. When you get that down, you'll know you're trimmed up correctly. Practice that with a full load of aircraft fuel states from 8.5 all the way down to 3.0 (lowest realistic trap fuel).
