Bump steer is certainly something I will add in the future.

I think a section talking about how to approach low and high grip tracks is also a good idea for sure.

Thanks for the feedback.

Cheers.
That's an awesome idea for low grip and high grip approach. The app has been alot of help. Well worth having on your phone.

For high grip, most including myself run a lower roll center with slightly harder springs, and for low grip, run slightly softer springs with a slightly higher roll center, but the differences are not huge and need to be tailored to the tracks you are running. To confuse you, on an extremely high grip track where I start to traction roll I will go down on the spring rate, but keep the low roll center. I do this to cause the chassis to rub on the carpet taking away lateral grip, and also having the side effect of keeping the cg lower. This helps reduce the chances of traction rolling.

Examples for my serpent S411...

...considering the serpent springs are...
- Spring white 13 lbs
- Spring grey 14.8 lbs
- Spring yellow 16 lbs
- Spring black 16.5 lbs
- Spring orange 19.5 lbs

On a high grip track I might run grey rears and black fronts with 0.5 mm shims under the hinge pin blocks, 5mm inboard upper links shims in the front, along with 4mm inboard upper link shims in the rear and 3mm outboard upper link shims in the rear.

For a lower grip track, I might run 1mm less shims on the inboard upper links both front and rear, and run a white spring in the rear and a yellow spring in the front.

For an extremely high grip track I might run the same roll centers as first example above (high grip track) but go with the same springs as example 2 (lower grip track)

Cheers.
Martin.

Here is a link to the app in the app store
http://itunes.apple.com/us/app/setup...9086?ls=1&mt=8

and here is a link to the app in the android market

Hey Martin how about an update to fix all the contradictions and mistakes in your app for eg. quite often the summary section might say stiff rear spring for push on power and under springs explained it says refer to loose off power which suggests softer rear spring. This app is full of errors and unless you have half a clue as to how suspension changes work it would be useless because it contradicts itself far too often, very dissappointed with this app is xxxmain book any better?

Can you add center diff to the setup sheet. I use your program for my 1/8th buggy.

No offense, but you might want to check what your reading. I've got the app open in front of me, and for the examples you give regarding springs, it's spot on, both in the explained and summary section.
You actually contradict yourself in your post, as you refer to push on power vs loose off power... two different handling conditions that require different changes to solve.

Personally, the app does a very good job of explaining was is a difficult subject (setup), and how different settings affect the car. However, it is still a complex subject, and you need to be careful and make sure you get the terminology right.

The XXX Main book is by Martin as well, and is a good compliment to the app.

Regards
eEd

I run 100 to 150grams more on the right side of my car than the left... It seems to give me an advantage turning right, and since the left turns are slow anyway, wouldn't that be better theoretically than a balanced car side to side ? If you apply the tire load equalization theory, of course...

Go to chassis settings explained go to springs and read under push on power and it refers you to same setting as loose off power but rear spring has more effect etc...i think it should read refer to push off power so its either a contradiction or a typo, if so then thee are many more
