Spit ix flight model question

[Finnster]

Hi guys,

 

I find the Spitfire quite touchy to fly- it feels like it constantly has the aft fuel tank filled.

It's like balancing on the head of a pin while riding a unicycle.

Strangely, twichy as it is, I cannot get it to do a snap roll in either direction.

I'm running

Windows 10

Nvidia 1080

32megs ram

intel 9900k Cpu

CH stick, rudder and throttle.

 

I've been trying to play it in VR, but my 1080 just doesn't have enough power to make it playable on my Pimax 8kx.

November will be new gpu month!

 

Any ideas as to why it won't snap roll? And should it be so crazy to fly?

(I've flown some aerobatic planes (Christen Eagle, Citabria, and a Chipmunk.)

The Christen eagle was almost scary it rolled so fast and with so little stick, but it never felt 'jittery' and uncertain in the way the Spitfire does for me in DCS. I must be doing something wrong.

Cheers

try adding some curves or meaby some saturation

It's your joystick throw. That's all it is. Remember that in the REAL Spitfire the real flight-stick has a much, much longer handle, I.E. a much longer throw. So for the same type of response you would need a larger movement.

 

The DCS Spitfire is made to be as close as possible to the real one as far as controllability is concerned. However this does not take into account our very short joysticks, which even with extensions do not come close to the real ones, hence we have a very twitchy plane until you develop muscle memory to compensate for it.

That's likely a big part of it... but the real Spitfire stick only needed a few inches of fore and aft travel for full elevator control. I've got about 3 inches of travel on my CH stick.

My problem with the model is more about its wobbly feeling- it feels a bit like a plane with its C of G too far back. Also... why won't it snap (or 'flick') roll? The Christen Eagle snap rolls nicely.

is it my set up? Or is it inherent in the Spit's flight model?

Yes, it can be pulled aggressively to stall AoA not comparable to P-51, for example, that is prone to flick rolls.

As for joystick, I would recommend to use saturation keeping the curve linear, because full elevator travel is not necessary.

It may help you.

Thanks guys!

Very helpful stuff. I wish CH products made an extension for their joysticks.

I know you can get one for the high tech thrustmaster stick.

I may invest in one of those down the road. Right now tho' I'll keep working on the joystick profile with your tips and that excellent video. And I won't be playing a lot until I get a new graphics card. My FPS on the Pimax 8kx are awful unless I set the graphics level way more than I'd like to.

cheers
