Flying straight on the F-5E

[shonist]

Hi folks.

 

wondering how do you manage to fly this in straight level?? in 30 mins of flight im 29:30 mins trimming it to fly level, im almost unable to keep the same altitud for a couple of seconds. always going up or down. no matter how much fine trimming i try (of course im a noob) but wondering if im doing something wrong? missing any feature of the plane to make this easier??

 

ty very much for the reading.

:smartass:

It takes a long time to trim it. In my picture it took 4 seconds to move it from 8 deg. down to 2.5 deg.

I know a F5 Pilot who flew in the Swiss Air Force. He told me that one has to constantly trim the F5 during flight. I will show im my sim soon, and let you guys know how realistic the flight model is.

Reading through the F-5 forum you'd see that it's a known topic that you can't easily have a level flight with the F-5 in DCS. Is it well modeled or not, I don't know... just that in DCS you can't just trim and forget about it.

 

I can say that you should first have it in level flight and only THEN attempt to trim to relieve pressure on the stick. You will still have to make constant adjustments all the freakin time, but they'll be small adjustments.

 

If you just go and try to use the trim to send the plane where you want, you'll never be close to have a level flight. It'll be a nightmare and the required adjustments will be much bigger and you,ll experience more "swings".

 

But ya, all in all, you can't just have a straight leveled flight with the F-5 (if you compare with other modern planes in DCS such as the Mirage for example).

Certanly that "up or down" is not realistic,I´m flying for 37 years and I´ve never seen a jet with that Belsimtek F-5E behavior.(Just check the VSI(Vert Speed Indicaton),not natural)

 

I was in the military for 7 years but it was a looong time ago but I also have a friend that flew F-5 a lot (Brazilian Air Force) and I use to talk about this issue,but I want him to test here in my place.

 

If I achieve this goal (bring him here) I will post it, even though I don´t believe that Belsimtek will change anything in this direction.

You know Belsimtek needs info for maverick systems, right? :D

Make your friend tell the devs how to implement those agm65

Of course a Mav would be good,but I would be more satisfied if they fix the bugs and the FD and get a F-5E with aerial refueling hoses. :thumbup:

That would really be great if you could do that. I've not been in DCS for as long as other people here, and since my beginnings I've read complaints and debates on how "unstable" the F-5 is (especially in pitch).

 

So, to have the inputs of somebody with real experience would be awesome. Thumbs up if you can achieve it!

[Kev2go]

Yeah and that's why autopilot is so nice in legacy aircraft that did have it.

 

No trimming like a madman for longer distance flights

 

 

F86f sabre in that regard also required a fair bit of trimming

How are the conditions? High, low, fast slow?

I dont have any problems trimming it out, it's not handfree but i dont trim all the time.

Try to trim it out as good as you can and then use the throttle to stay level.

[Sylosis]

Unstable and trimmability are two different things and the F-5 is definitely not unstable.

 

There are even basic SE GA planes which simply can't be trimmed for level flight. That's nothing special and I'd very much perfer a fighter that is sensitive and highly maneuverable in pitch than a way too stable and slow responding plane ;)

 

Apologies if my choice of words was poor. I was indeed refering to "trimmability" when using the word "stable", and I wasn't refering to "stable" in the sense of flight mechanics/dynamics.

 

Thanks for pointing it out.

I routinely fly distance in the F5 with only occasional trimming. Are you changing speed a lot? I sometimes set trim and walk away to grab a quick snack from upstairs. Have you tested the control play in your stick and put in appropriate deadzone?

[dimitrischal]

Set first pitch, then power and trim. In that order and bear in mind trim changes with airspeed and fuel consumption or weapons used so you actually need to trim for the airspeed you are targeting.

 

And most importantly give it some time, the plane needs time to settle and you need time to get a feel for it so avoid excessive trim changes.
