Wet Astro set up for C4.1

[ejw]

Evening All

New to racing so have limited know-how when it comes to set up etc, raced Sunday at Stotfold (Astro) and decided to start with the below/attached set up (Paul Bradbry Tallywain) in the hope that the astro would be at least similar in grip level etc.



Sunday turned out to be a fairly wet start to the day and i arrived to a difficult track where one corner would provide reasonable grip followed by another that was like ice causing a spin out if any hint of power was put down and huge understeer if i tried to turn in off power.

Started on Yellow Minispikes and using Green Minispikes seemed to aid very little and a fun but very frustrating day was had. Can anyone provide any insight into best things to start with in terms of looking for more all round grip, even general non Centro specific advice would be appreciated, when things are more slippy than anticipated where do you start?

Please Help!!!

On slippy astro tracks we usually start with Ballistic green rears for max traction.

Thanks Tony

Haven't used ballistics, will have to look into getting some for coming months outdoor stuff, front and rears?

Hi mate, I was at Stotfold on Sunday as well. I was running the RB5 Vega. I have endured weeks and weeks of the pain you are feeling now and unfortunately there is no miracle cure. Ballistics help, but the difference is minimal so they are not the difference between having grip or not. For me, the things that helped me most were moving my rear camber links in one hole on both the hub and the shock tower and buying the optional rear hubs to add more toe in.

The main difference for me though is practice. I have been trying to lay the power on gently from day one, turning in gradual, avoiding sudden movements, braking gently and only when approaching a corner but before turn in to try and keep the back end in line.... everything I thought would help basically but to no avail. This sunday though I finished third in all 3 heats (PT failed in the final ) and things felt more under control. I was still two laps down on the winner, but Simon is an F1 status driver so there is no shame in that for me as three weeks ago I was coming last week in week out

So, whilst you can make some changes which will help (never driven a b4.1/c4.1 so cant comment on specific set up changes) the biggest difference will come from you learning the track and practicing.

From my experience, assuming the track layout is as was on Sunday then turn 1 at the end of the straight is ok to coast round at speed, turn 2 you have to be very gentle on the power after the small rumble strips/jumps unsettle your balance, turn 3 into the tabletop is slippy, turn 4 after the tabletop is ok as the camber helps you, turn 5 is awful - next to no grip, turn 6 is the opposite - lots of grip by comparison, turn 7 which takes you up the hill was medium grip, turn 8 into the wall was quite slippy if you werent carrying sufficient forward momentum, the wall itself (turn 9) was ok, as was turn 10 back into the straight.

Once you learn what each part of the track is like then this in itself will help you to drive accordingly.

When it's wet or slippery i always turn my throttle exp down on my trany this helps alot

Skye,

Hello mate thanks for the advice. I noticed you were going well and didnt seem to be suffering in the corners as badly as i was. Tried hard to control my throttle finger but you know how it is, as soon as someone gets close get all over excited and punch it which invariably just spun the car 360 degrees.

Very frustrating watching the 4wd's power through every corner wet or dry!

But like you said Simon was flying so it can be done, it's difficult when your inexperienced to know if your just a bad driver which I can live with or whether you are fighting a badly set up car!

I was running 0degree hubs on the rear and do have option of 0.5 degree in my box so might try that next time.

Turn 5 was just silly, had to turn in 3m from apex and just coast in and still ran wide and getting on the power coming back onto the straight had me spinning all over the place.

Thanks carpenterdean

I did dial down my esc to make car less brutal on the acceleration etc but didn't think of adjusting tranny so will definatley give this a go.
