I wonder if you media blasted the wing so it had that textured look if you could start a new trend. Jeebuz if you need for the wing to be seen, throw a sponsor sticker or two on it!

I'd love to see some pics & an explanation of what you have done to lighten it.

My son's old b4.1 was 1481 with 1/4 oz in each triangle, no balast, 4800mAh shorty, spektrum sr200, savox 0253, Tekin RS/13.5...other than that just the average FT that was converted to a worlds car.

Here's how my center mount esc made of the rear chassis plate turned out:

So maybe I am wrong, but there really is no advantage to having ESC above the battery in the middle is there?

Maybe someone can report back after trying it, I know a few people tried it but I dont remember ever seeing someone post results.

We used to do it in the 90s. Kyosho, Losi, and Durango all think its right. 1/8 scale experience tells me that narrower cars have their advantages, but are more easily upset left/right where a wider layout tends to be more forgiving. Durango went off the deep end toward this goal in their 4wd and they still got beat by the same basic B44 saddle pack setup that's been around since right after the BJ4. Obviously wasn't a game changing advantage that was a requirement to compete -- durango certainly did well with it though!

I think I'll wait and see. In my experience, most club racers could benefit far more from learning how to properly maintain their car car, especially replacing worn outdrives, cvs, foams, and setting their differentials correctly than they could from re-arranging their electronics. If you're re-arranging your electronics and expect significant results, you're looking for at most 1/10 of a second and you're already an amazing driver with super dialed cars to begin with!

I run a 4100 shorty, ballast, 1/4 in each triangle abd 1/2 next to the receiver for 1530 grams. even without the 14g next to the receiver and the ballast, I would be over 1500. It must be in the electronics. I even have a LP servo.

I think makes for cleaner wiring though, no?

I tried it this weekend. It yeilded more steering because of more weight over the front by moving the battery foward. I did not give up much traction because of the esc being added over the rear. I yeilded the same fast laptime. However, im still not as consistant with it just yet. Gonna give it one more weekend and if I cant pull my consistancy back its comming out and I will be back to the old layout.

You are taking a fairly heavy object and raising it an inch, this will affect your CoG and make the car roll more.

I hear a lot of different theories about shifting weight forward and whether steering increases or decreases. Over at Tune with Camber Links thread, Fred Swain is making the case that moving weight BACK increases steering as it changes the roll stiffness, http://www.rctech.net/forum/11647311-post1112.html

Maybe the ESC over the battery shifts weight back increasing steering? Or the slightly higher center of gravity adds more roll?

Personally I like the look of the esc in front of shock tower, was it not possible to keep the battery in the same position as you had it before? I'd be interested in seeing what just the esc mounting position does with everything else the same.
