(Without fan at about 30° Celsius, astro track, straight about 65m, 14 teeth pinion). The wight is in the back as much as possible, spring is pink.

Car went great this weekend,
BUT:
just some little, hard "Bumps" about 10cm high and 40cm wide, and the "nose down" was dramatic. Changed oil in the back to 300cst: a little bit better. Moved the upper mount of the suspension inward: not better, reduced the travel: the problem was amplified.

Changed everything without the oil back and get 3. overall (just 5 competitors).

Planed my next changes:
Building some pistons 4x1,8, oil: more cst, building a "bump" for testing in the backyard.

You can see my car in this Youtube video: http://youtu.be/Yjx15m04iRU

I see that you moved your esc location to behind the battery. How did the truck handle with the esc in the stock location? Just a thought, maybe by moving 80 grams of weight that far back on the chassis is accentuating the rear chassis slap causing the truck to nose down. In my experience reducing droop and lowering the truck makes the problem worse, while increasing suspension travel will improve the flight characteristics of the truck.
