(Nice subject, isn't ?)   :)

Hiya

A) Left foot braking, I brake withe the left foot, but im not using Left
foot braking... (using the brake at the same time than the throttle for
balancing the car ...)

are the fastests guys using it ? (me 1:08.14 at the glen demo)  I dont want
to be fastest, im looking for consistent times ... will LF braking help me
?

B) What steering linearity are you using ?

thanks :D

I've been testing GPL for quite a while and I don't hang around for long in
the corners... I use a CH Flightstick Pro joystick which of course is one
input on the single Y axis.  I think Alison, John Wallace and maybe a couple
of the other testers might use left foot braking, or at least use the brake
and accelerator on separate channels for the race starts.  I couldn't say if
they find it in advantage for them - I'm equal in terms of lap time on the
tracks on which I specialise, that's all I can say.

Hi Mike

I have been in the habbit of left foot braking in Nascar 2 but
mainly it's because I don't need my left foot  for the clutch.
In GPL on the other hand I have the clutch and make plenty of
use of it. As it was mentioned by someone else braking at the
same time as accelerating is the same as lifting off the gas
pedal as I have my accel and brake on the same axis. My clutch
use Joy 2 analog 1. I think I will try seperate axis for accel
and brake as an experiment.

You should realise that Mike is mental though.. :-)

I have gas and brake split onto separate axes and I also left foot
brake, often against power. I find it easier to stablise the car into
corners and to make minute adjustments. I don't think the split helps
at the start except at tracks like Spa where you are on a hill and
need to hold the car on the brake - with split axes and left foot
braking you can hold the car on the brake and still maintain optimum
revs.

For starts though a clutch is pretty nifty, although difficult to get
the hang of. As you would expect from GPL every car gets off the line
differently, and after driving a Ferrari for a while and perfecting my
starts I had a hell of a time going back to the Lotus and either
bogging down with too few revs or melting my tyres all over the track
in a frenzy of wheelspin. Starts can't be practised enough though -
you will spend hours trying to catch the fast guys and forlornly
gunning for pole, but if you can get on the front row and outdrag them
you can really spoil their day even without being the fastest car out
there.

Cheers!

I guess you are using a steering wheel (since you talked about pedals, I
guess so).
Using a joystick, I had a terrible time with unwanted steering until I
switched to
nonlinear steering.  But I'll bet a wheel is much more precise.  (Is it?)

Hehe, why do you think they used steering wheels and not sticks back in -67?

Of course it is more precise, so you have only one thing to do: Get a
Wheel!!!

I'm pretty sure they did all kind of tricks back in -67. The famous Senna
toe-and-heel technique (braking and throttleing at the same time, also called
trailbraking if I'm not wrong...), wasn't invented by Senna, he just applied it
in a winning way with the turbo cars, it was much older, you can read about
this technique in Taruffis book from the 50ties. He explained techniques with
different setups, the gas in the middle and the brake on the right, and the
traditional, from left, clutch, brake, gas. The idea was to use the heel on the
"main" pedal, and then feathering the secondary pedal with the toe.

I'm not sure whether they used their left foot or not, I believe they didn't,
because using the left foot on the brakes would not allow the driver to change
gear before the braking is all done. I guess they preferred to use the right
foot even for the trailbraking, so that the changing of gears and
braking/trailbraking could take place simultaneously...

We, on the other hand, don't have to clutch, so we can use left foot braking,
and there isn't any doubt that this is the most effective way. Braking and
throttleing at the same time extend the possibilities for car control.

Anyway, It is cheating, no doubt (if I am right in my assumption that they
didn't use their left foot for braking), so we have to find out if they really
didn't use their left foot, so that we indeed will be driving these cars like
they did back in -67...

What Senna did wasn't heel-and-toe, his style was to continually pump
the throttle staccato style to utilise all the grip available and to
be back on the power as soon as it was possible - it turned out that
such a style perfectly suited the early turbo cars as it kept the
boost pressure up and gave him extra power out of the corners.

Senna really got into this after the turbos went. Most top drivers were adept
at keeping the boost up in turns in the turbo era, but Senna used this
"blipping" in order to get the throttle all the way open faster than anyone
else rather than the more conventional smooth throttle action.

I seem to remember a telemetry trace on a BBC2 documentary a couple of years
back showing how it was done compared to another fast driver of the era (or
slow depending on your opinion of Jonathon Palmer ;)

I know he did this while turbos were prevalent since I recall an
interview with Prost where he described how he knew of this technique
of Senna's and had been urgend to try it thanks to the benefits it
brought. He had tried it and couldn't make it work.

Yes, I saw that. Bloomin' strange I though that Jonathon Palmer seemed
to take great satisfaction in pointing out how Senna pulled out 0.2s
on him through one corner through superior technique - I'm not sure
too many drivers would happily describe that about their team-mate!

They should have been fitted with sticks.  :-)  If only CH were around back
then to make the Flightstick Pro!! (hopefully with more robust springs than
they fit now, however).

to start, for trailbraking (thats how is usually called the process of keep
braking into the curves to keep balancing the cars), you should have a wheel
with separate axis as Nascar Pro Racing Wheel if not, you are doing nothing
because braking will cancel throttle.

   Hmmmmm, now you got me thinking! And scared! I dunno if I wanna be that good,
hehehehehehehe. Gee, I ain't even got around to rigging up the dual axis caper yet. After
that I might try a little linear testing and see what happens :)
