That's not right about the MR-2. The moment of inertia has nothing to do with understeer/oversteer balance. At the limit if there's a yaw torque into the turn it'll oversteer. That comes down to tire lateral force distribution between the front and rear and that's about it. All the moment of inertia controls is how large the yaw acceleration is given a certain yaw torque. A car with a huge moment of inertia that oversteers will still oversteer. It'll just accelerate around the yaw axis more slowly than a car with a low one (it'll spin out more slowly). Low moment of inertia does equal 'more twitchy' though and typically a design goal is to get that as low as possible so the car responds to the yaw torques quickly. That part's right.
I don't think I claimed it having anything to do with the overall balance, just that most fast setups on forums are biased towards oversteer under almost all conditions and together with low moment of inertia, they produce this "snap oversteer" if not driven properly. On the otherhand, default setups on Dallara are good way to experience how it affects the behavior on a car that is set up for massive understeer.
Late Model, Solstice and Impala show the handling of a car with high moment of inertia, all three cars feel very "lazy" and transitions happen much more slowly, making them easy to drive but little bit unresponsive as well.
Driving downforce cars will forever ruin your Skippy career, just because of how it affects braking
All that extra downforce means you can go 100% on brakes at the start of braking zone and then ease off as speed drops, unlike in Skippy and Solstice where you need to smoothly step on the brakes to avoid lockups and then stay fairly steady all the way.
Yeah, little miscommunication there. You were talking about "how much" and I was talking about "how quick", it was probably the MR-2 mention that threw me off since on paper that sounds like quite twitchy car in hands of inexperienced driver. It makes for better discussion if both side would talk about same thing
Anyhow, about Skippy and SRF. As I mentioned earlier, you need to take in account the possibility that most setups you see on forums are dialed in to have oversteer available at all times and never understeer. I don't think Skippy has received any changes since beta and old setups work just fine, the fastest way to go around was to set stiffest rear-ARB and front suspension to lowest setting for high caster. That gave very pointy car that was easy to balance even in middle of a highspeed corner without major lifting. Last time I tried the car, it felt very understeery but that's probably down to steering that requires a lot more work compared to Mazda and Dallara.
Looking good. I can't wait for this. It's the only real racetrack I've ever driven on and I've been there as a spectator so many times. Hopefully it'll make it for next season. I just hope it appears on lots of the scheduless. With the indy and GP tracks it should suit most classes.
I did the one one free Radical trial a while ago. Since I didn't buy the Skippy I don't know about it, but read many posts that stated the SRF was much worse than the Skippy. As you mentioned ealier, lift throttle resulted in spin, not oversteer in the SRF (and perhaps the Skippy).
Before the recent update, rather than mess with setups, some players adjusted the throttle throw so that zero throttle pedal translated into 10% to 20% throttle input, and then adjusted the brake bias in the setup rearward to compensate when driving the SRF (or the Skippy?). I don't know if any players are still doing this with the current update.
I bought the Skippy today, driving it at Limerock It seems stable and predictable as long as you watch what you doing with the right foot, Initially I was a little disappointed with the FF, the car feels like it wants to steer all by Itself ( using corrent polarity in FF settings) but at Mosport even on lap one it was being five again at Xmas.
It maybe partly nostalgia for GPL , but one thing I do know the track is in another league since I drove it In GPL ,combined with this car driving the same corner always feel that little bit different each time, the Solstice is the same.I think thats whats makes you want to try one more lap.
Radicals at Road America is my favourite combo. My last race there people were asking whether to use tall or medium gears and how much fuel to use just before the race started! I found this a bit worrying
Wow just noticed I'm leading Div 2 of the Radicals, my best ever position in any series
well done (and you AlienT, can't leave a fellow celt out)
i really like the dallara and i'm finally getting my head round the setup, found 1.5 secs in just 5 laps yesterday after just 1 little change. i know i could (should ?) just find someone else's setup that suits me but i prefer to work the damm thing out for my self
well today i came across my first fasttracked A licence holder. if this guy is an accurate example of fastrackers then all the doom sayers will be disappointed. he was obviously slow as he's only been an iracer for this season and had qualified as an A licence half an hour earlier so was attempting to learn watkins and the dallara from scratch. but he was safe and despite being an australian (just kidding) he was courteous, pleasent and polite. infact the only issue i had with him was him saying i was english despite celtic logos all over my wings and sidepods
