The most uncomfortable pitchup issues

Hi all.

I just got the spitty, very nice plane and all except for the horrible pitch up issue, the nose always pulls up no matter how much nose down trim I apply, it is impossible to fly in a straight line or formation with it currently.

Can anyone tell me if I am doing something wrong?

Do you have any duplicate bindings in the controls?

I really doubt it but will check in 5 min and report back.

Nope, no other controls are bound or affecting the pitch

1. What flight regime?

2. Power Settings?

3. Have you any Curvature applied to your elevator control axis?

4. How are you applying your trim (button/axis?)

Pls make a short flight and post track of it.

Ok, will do so tonight.

Are you 100% sure you're trimming down? Check the trim indicator needle, make sure it moves. Or just look at the wheel.

Otherwise it does sound like a binding issue, like mentioned above

Hi, here is a track file of me doing startup and taking off. I then get to various speeds and leave the control in neutral so you can see how it still pulls up so much even with full nose down.

Please don't mind my incorrect startup and general rubbish, I just got the plane so even getting used to the breaks is interesting but I'm sure the pitch issues shouldn't be like this.

Check my reply above, it has a trackfile included. You can see my apply full nose down. Let me know what you think.

The first thing I saw - and suspected - is too much boost on takeoff.

Full fine pitch

Boost - do not exceed 8 lbs pressure

Nose Trim - neutral or slight trim down

Rudder trim full right

Cheers

Boost is irrelevant. With full nose down trim his Spit should want to fly itself into the ground no matter what power settings. About 40-45% of back deflection of physical joystick is needed then even to maintain level flight, let alone pitch up.

Cintra, the plane behaves like you describe when you've got "game flight model" turned on in difficulty options. You might want to check that one.

Just checked and it isn't on. All settings are quite usually at full realistic when I fly.

This is quite annoying because even trying to shoot down a slow, level flying bomber is difficult when I can't fly straight lol.

Alright, I'll use less boost on takeoff and apply the rudder trim. Thanks.

But that still doesn't explain the inflight pitch up issues that make hitting a level flying plane near impossible?

I could see on the track you were able to operate trim wheel surprisingly fast. You use some analog rotary device for that? Maybe DCS doesn't work correctly with it (for example there was a bug long ago, when planes had their trimming controls fully animated, but the flight model was not reacting to them because of unused FFB controllers being plugged to PC).

Bind elevtor trim to something on your keyboard, unplug all controllers and check in free flight mission if trim works OK that way.

Yes I have it bound to an analog input, I do also have it bound to normal buttons on my keyboard and have simply used my mouse in the cockpit to put the trim down and it made no difference. :(

For now I've just had to remove my force feedback program, made a smaller deadzone and much wider curvature of the input so I can just apply a small amount of nose down at all times. But it really shouldn't be necessary with full nose down trim, this is so frustrating.

Agree with this!

Game Flight Mode??

Are you ABSOLUTELY SURE you don't have the "Game Flight Mode" box checked??? This is EXACTLY what happened to me about a week ago. I reinstalled DCS stable version. I had to redo all my flight controls. Found out I had the little boxed checked for "Game Flight Mode". Unchecked it, and all was good!!

Absolutely, I will just toggle it on and off when I'm back my pc next...

And unbind this axis from trim. Use buttons for this.

This is how it was originally, it made no difference.

Maybe someone asked this. Did you try different scenarios, MP,SP,quick mission,cold start, hot star, air start?

Yes, I notice that starting in free flight reduces the pitchup. Weird.

When i set neutral trim on my end. During take off i have to pull stick to avoid prop strike, at low speed it is ok, but once spit got to 100 mph nose down pitch is quite strong.

When you set max nose down trim and you still get nose up something must be off "big".

Join MP server it can be aerobatics server this one is most populated easy to find, test this if your issue is gone there, it mean that something wrong with you local settings, if not i cant help out of ideas.

I had this pitch up problem with trim not working, the fix was that

I had missed two updates as the auto updater had stopped working.

It wasn't the only problem either I had multiple crashes due to key bindings disappearing.

Fixed the updater, updated and all is well again.

Hope this helps.
