Try some softer springs up front and a degree or so of toe out

Spenzalli,
Yes I agree. My current set up is:
springs Front - purple,
Rear - copper
shocks oil 50 wt.
Sway bar Front - 30 deg from flat
rear - flat
The purple/copper combination was recommended so I am trying it.
Maybe increasing the rear sway bar setting and decreasing the front sway bar setting will help tune out some understeer. But in the end I think I will need to return to using the same springs front and rear and fine tuning the handling with the upper shock mount locations.

Hmmm. I run a white or yellow up front and a copper in the rear. Either have the front sway flat or disconnected. Shocks up front are in the outmost hole on the arm and standing up (I have the C/F shock setup, and I use one below the highest setting). 60 wt. oil all around (or is it 55? I can't remember now)

If you've seen pics of the track, it's pretty big, and traction isn't an issue (too much traction has been). Basically it's the J.Linn setup with a few minor tweeks to keep tire wear even

hi curve tracer, att is a setup i used on a high traction track at the prewolds at brendale au, the car handled good, with the driver the limiting factor, i was having trouble back then setting up my diff and it started to fail in the 16th final, and with marshalling after that and straight into the 8th final i had no time to fix it.

Default CD3 chassis setup

Hey Mcfly,
Thanks a lot for the setup sheet!
Wow you are running a large difference between front and rear spring rates.
How much front understeer are you experiencing with this setup?

Trusty: I know it was a bargin.. Your assistence is always welcome, the day you had a drive was just like old days

I finally finished running the Hyper 8 in.. I thought i could drive, but i ended up in the garden a few times, lucky there is a fence around the pool.

Haven't ruled out doing some sort of onroad racing as well, but all the guys that use to run at BRCCC have all moved on to do other things and it just ain't the same.

Talk soon,

BB

Man you have been working too many long hours dude... i see the problem your chassis is past it's use by date, way too many scratches. Time for a new car dude. Would never catch any of my cars looking that bad.

P.S: Bring on Brasil as soon as i can get my R/F cable sorted out i am in business for Monday morning.

hi curve tracer with this setup the car was very evenly balanced, it was oversteering slightly with 1 step softer springs on front on transition from on to off power on left to right turn but those springs fixed that . and the only time i got understeer was on turn1 right hand sweeper off front straight( it wasnt too bad though, but consistant)

Hmm. That rear end looks a lot like mine! I need to see about adjusting those shocks to give the car a little more ground clearance. Maybe I'll unscrew the ball cups just a bit and see how that works

Yes I was running too low ride hight (and thin oil) for our track for some time - was bottoming out on the uneven parts. I am up to 7 - 8mm ride hight now with thicker oil.

The Regulator plug is shoe goo'd onto the carbon deck.

I may try that thicker oil in a bit. I looked over my LD3 and noticed I had different ends on those shocks. Looks like I took the ends from the rear upper arms and used those for the shocks. Makes it a little harder to pop the shocks off the lower arm, but it does give them a little more lift and they won't pop off in a crash.

How come you didn't use a switch?

Well I wanted to put regulator in receiver box so it would of been
Battery (cable to top deck - so i can charge it ) Regulator plug (cable into rx box) Regulator (cable out of RX box) switch (cable back in RX box) Receiver. I thought be easier not using the switch as they are no real gain for me.

(The Battery & Regulator plugs are keyed - not the normal plug anyway connectors.)

Default LiPo Packs

Hey au_Nightmare,
How much race time can you get from the LiPo packs? Three qualifying heats, plus practice?

Running Sanwa (airtronics) digital steering, KO analog throttle used hmm 230mah I think it was for the 3 qualifiers. Should be able to get well over one hour on it - my 950 nimh pack lasted that long (a enduro) with I think over 200mah left in it on a discharge (stopped the discharge after it went past something like 200mah)

Before I try any long events im going to install some undervoltage warning - then atleast I know I have discharged too far and know to say bye bye to the pack (and hello ebay - hahaha nah I wouldn't be that naughty)
