Set up help
Can someone please help!!
I have a kmc converted zx5, i run it on polished wodden floor at faversham. For ages i have had problems with the back end staying where i want it, my dad also has the same problem with the standard chassis. For example i will go into a corner but if i put to much power on the car will swap ends! But what i dont get is that i can hear the tyres squelling with grip. my current set up is pale yellow springs all round, 35wt in front 30wt in back, front shocks in middle hole, rear shocks in outer hole, 10 deg hubs and a15 block on rear. oh and i also run 13.5 brushless and a trakpower 4800 saddle pack with 100 grams of weight in the back. cheers Will |

Try A30 in the rear that will help and put a two notch shim under the 'B' block, you could also move the bottom rear shock to the Middle hole and lenghten the rear camber link. All these will help with rear grip. HTH. almost forgot to say put the kit 70# silvers back on the front too.

B block from memory is the one in front of the rear gearbox that holds the other end of the hingepin on the rear. will possibly be popping up to faversham on wed night so will show you if you are not sure

will the SP knuckle & hub LA254 fit on the original standard ZX5 or RTR kit without any modification? will it be a direct swop (without replacing arms nor CVDs)?

Might seem like a strange question, but what colour are your balls ? On the SP you should be running the silver coloured balls on the knuckle, they are a different design that lowers the ball joint and reduces bump steer significantly. |

I have practically zero bump steer on my ZX5-SP ..... anybody who knows me will tell you I'm far to anal about such things to stand for any at all!!!
Sorry to say it but sounds like you have built the car wrong! Post up a pic of the front end assembly please and we'll work out what is wrong. |

I am just uploading some pics. But I have a strong suspicion that I am going to be made a fool of - publically!
5 mins and they'll be up http://a7.vox.com/6a00e398f1628400050109d07c9d7f000e-pi http://a4.vox.com/6a00e398f1628400050109d0fe3b7c000f-pi http://a2.vox.com/6a00e398f162840005010980c97b22000b-pi Thanks for the response guys. Looking forward, (nervously) to the response. Last edited by Benh; 14-01-2009 at 09:31 PM. Reason: pics added |

zx5
is the rear shock tower the wrong side of the bulkhead?
|
#93

How can you see the rear bulkhead from the pics
Both ends are on the right way round. |

I will have a look when I have my car in front of me but from memory that all looks to be assembled correctly.
I have checked my car since your first post and there is a tiny fraction of bump steer but only in the parts of the travel where if your using that area bump steer is the least of your worries....... How much droop are you running on the front, notice that you have your hubs low like me .......... I run the shock length a little shorter than stock IIRC |

help with set up
Can any one tell me what set I shood do for astro and grass and what mods or parts i shood get for my zx-5sp kit I'v got coming as would like to get it set up right from the start but no I will have to tweak it a bit still for new tracks when I go to them and for my driving.

That will get you going, only a few changes from then ..... Main change is that I am now using the middle camber link position on the bulkhead both front and rear ends. Often run 10 degree castor blocks on the front too. Run it like that for a bit then let me know what you would prefer it to do handling wise if it's not perfect for you and I'll tell you how to change the set-up to suit. I have a personal preference which means most of the time I run #70 silver springs on the front which have had 1.5 coils cut off. Ride heights quoted as the gap between the top of the upper spring platform and the shock cap. For carpet I run a very similar set-up but ..... Lime green springs (#75) all round, in outer holes on the wishbones and a 1.2mm rear anti-roll bar ... no other changes. The ZX5-SP is a VERY easy car to drive, this set-up will give you loads of steering without making the car feel too twichy. |

Thanks
Thanks for that mate I'll let you no how I get on. But can I by a spring set with all the spings so I can try different ones? As can only see one pear at a time for sale.

Kyosho only sell springs in pairs.
Trust me, all you will need is silver #70s (ZX5 kit springs), two pairs of fronts if you want to try the cutting... lime green #75s front and rear #68 and #72 rears. You will need nothing else on grass or astro! |

Roger is right again, we mostly ran kit silver (there may be another silver-stronger spring), its tyres that you will mostly have to get used to and adjust for grass & astro, wet/damp/dry/short/long/grippy/whatever. ask around where you are racing.

well looks like I found a good setup for the FS on carpet, it will be posted on Petit RC as soon as Arn0 will be back I'm sure. Car was fantastic everywhere on the track and produced laptimes which I thought were way beyond what I thought I could get.
