Why don't GPL car "fish-tail"

Many times when a car gets sideways in real life, after correcting the slide, the car will swing back the other way in a series of fish-tails, or "tank-slappers". I don't believe I've ever experienced this in GPL and all of a sudden I'm wondering why?

Coming out of the 2nd lesmo is way too easy to fish tail , just especially if u get on the metal too soon and lift off quickly Capp >Many times when a car gets sideways in real life, after correcting the >slide, the car will swing back the other way in a series of fish-tails, >or "tank-slappers".

What sort of wheel are you using? When I used my old T2 I never had any fish-tails, but with my Wingman FF i get it quite often. I guess it is because the forces in the FF-wheel makes the wheel react more realistic(wheel moves by itself reacting to frontwheel direction etc) and therefore causing the car to fish-tail. There probably is some more "physical" explanation for this, but I don't know it! :) /Martin Sent via Deja.com http://www.deja.com/ Before you buy.

Your not driving hard enough. ;) I think the tank slappers are caused by you getting behind on your steering. It is easy to do. Your counter steering hard then the rear tires get grip and snaps you around the other way then you counter steering the other way and then the rear wheels grab and throw you around etc... then from there your fight the car and trying to catch up in the steering. It's a driver error if you get into a tank slapper. I think the reason why we don't get much of them in a sim is becuase are wheels are small and only have a limited turning range, so it's quicker to turn the wheel, you have less chance to getting caught behind in your steeering(Mr. Slowhands). Nascar Drivers are famous for tank slappers becuase they have a 10 foot steering wheel and it turns and turns and turns. Plus they are used to turning right. :) > Many times when a car gets sideways in real life, after correcting the > slide, the car will swing back the other way in a series of fish-tails, > or "tank-slappers".

Really easy to fishtail when you first go from single axis pedals to dual axis... come off the gas.. induce power off oversteer (the car gets loose).. panic! It works for me! -- J.H.Vizoso
You're not tiding soft and high enough... they sometimes do for me (usualy while I'm leading... ouch!). Jan. ----
Maybe because you're such an excellent driver? <g> I've fishtailed in GPL plenty--often followed by a resounding crash. Jerry Morelock
Get a FF wheel.. and hang ON!! David

I agree. You can make the effect by putting the power down too much out of a corner but unfortunately there is not fish-tail effect from correcting your turn:-( >Many times when a car gets sideways in real life, after correcting the >slide, the car will swing back the other way in a series of fish-tails, >or "tank-slappers".

The reason is because in most cars you drive on the road are NOSE HEAVY. and in GPL the cars are HEAVY in the TAIL. So in GPL the back end will keep swinging around until you do a 360 and not fishtail. -- Kevin Anderson ICQ # 6769389
I can tell you, I have an FF wheel and in GPL I *do* experience this. With my LWFF I get all the fishtail effect I ever want to feel, as the tires catch and slide and you have to work the tendency of the front wheel angle causing the rear getting out of shape on the rebound as the rear tires catch. It feels pretty realistic to me compared to the fishtails and donuts I used to do in my old rear wheel drive '67 Chevelle I had (and abused) in high school. Of course my front wheel drive Honda doesn't do any fun stuff like that, but at least I can still do that in GPL. Are you using an FF wheel?

I use a constantly-in-a-state-of-repair Thrustmaster Nascar Pro wheel/pedals. I set all my setups to 15:1 steering ratio, and recently changed the core.ini to eliminate the variable ratio steering below 60 MPH. (Boy that takes awhile to get used to after driving the other way for so long). How does having force feedback affect your lap times? -Tony

On Thu, 28 Oct 1999 11:09:19 GMT, Martin Granberg Well I've a MSFF and midpoint at the parabolica right towards the end is when I experience fish-tailigin if I fail to stick to my line. Also I am guaranteed fish-tainling at the start of races if I get too e***d with the throttle.

: Well I've a MSFF and midpoint at the parabolica right towards the end : is when I experience fish-tailigin if I fail to stick to my line. Also : I am guaranteed fish-tainling at the start of races if I get too : e***d with the throttle. Are we talking about fish tailing - the wagging side to side of the rear end of the car before either disaster or miracle recovery - or just getting sideways. I very rarely get actual fishtailing anywhere except out of Lesmo 2 at Monza. I assumed it could only happen under power on where the front has plenty of grip but the rear hasn't. Anyone able to actually explain fishtailing? -- Richard G. Clegg Only the mind is waving Networks and Non-Linear Dynamics Group Dept. of Mathematics, Uni. of York www: http://manor.york.ac.uk/

you gave yourself away when you wrote "tank slappers". You've raced on two wheels too much. As you know, when a cycle gets out too far, it's not the same as a car, in the car you just peddle and use the wheel. On a ***cycle, your weight loads the suspension when the rear tire finally grabs, that's when a couple of ugly things happen. You might get spit over the front or get one or even two more tank slaps before getting spit over the side. The two wheel question is not how to stop the slap (because your body is causing the problem and you probably don't have enough control over your body at that point).....but before all this happens...(cus you been in the corner before) flat trackers pull left foot off and lean foreward to keep the back wheel from grabing abruptly, moto-xers do the impossible and stand up and lean foreward & keep the throttle wicked up.. ssshhhh, and road racers just do 2 tanks slappers and crash. Oh, you won't find this happening in speedway, they don't use much suspension. > > Many times when a car gets sideways in real life, after correcting the > > slide, the car will swing back the other way in a series of fish- tails, > > or "tank-slappers".

I think you could be right. I don't remember this happening in the past but I seem to be doing it all the time with my MSFF. I thought it was just because I was such a bad driver - great moment of the week was breaking 10 minutes (by 0.13 seconds) at the 'ring. -- Tony Whitley
