You mention that you moved the battery forward, and it gave you more on-power steering, did this have a noticable negative effect on off-power steering at all. As per my previous post, I only got the static corner weights, on my car checked properly after the first day with the car, initially I had the battery in R1 and moved it to R2 when I set the corner weights/balance. Now I had the car out for its 2nd run last wkd and noticed a lack of on-power steering compared to the 1st day (only changes were the CW's), after reading your post about the battery i've came to the conclusion I have gone the wrong way on this.

I have worked out that I have a F46/R54 spilt with the cars corner weights/balance set with the battery in R2 and 30g ballast. Do you have your F/R weight distribution at hand to compare?

Been doing a bit of research on the net, mainly on scale race cars, while many say 50/50 is the holy grail, this can be somewhat misleading, a front engine RWD race cars for example can go as far as 40/60, but what is interesting I couldn't find anything other than 50/50 mentioned as the ideal for a AWD race car.

I'm now thinking about moving the battery to R1 again, and moving the ballast forward to get the weight distribution closer to 50/50 for a more neutral setup, any thoughts on this?

If anyone else has any theories on this or has their corner weights handy, please post them.

Cheers

MD> The R1+spool position provided more mid/exit steering. R2+spool seemed to initiate more entry/mid. You may not have approached it incorrectly. Surface/conditions being different day to day, dependent on sauce/track groove. What did you start with a setup?

MD>
R1 configuration – Front 630 grams / Rear 677 grams
R2 configuration – Front 612 grams / Rear 696 grams

MD> Share your setup that you running. Great advice that I got once from Ron Rossetti & Gil Losi Jr. was that the three things that matter in R/C – tire/shocks/body. The rest is all about lap times and practice. I would say that in the history of cars that I have owned – some steer from the rear (FK05), some steer hard from the mid/front (TC6) and some are more neutral (416/417). A lot of that is drivers preference. Especially with new cars, it is good to try different setups. Motor/power has a great effect on how a car feels on the track. Setting up a mod car would be a much different approach than setting up a car for the 17.5/13.5 classes.
