I developed a new top deck (low cost) that fits perfect in serpent s400 for high capacity LIPO Bateries, using high density fiberglass and Carbon fiber. (2 layers of fiberglass and 1 carbon fiber) realy strong anf little weight, 2,5mm.

By the way, i'm using the oil dif in rear and front too, I made a small part (steel) that works perfect in the front, now I have more steering and a lot of run time.

The picture show the work in progress top deck, easier to see without the last carbon fiber layer.

Finaly I can use my 2,5T and the car still running,

Already tested, and works fine, realy perfect.

Regards
Robert

We did, they worked nicely with 3.5+3.0 blocks in the front and 1.0+4.0 in the rear on a tight carpet track.

I'm using 10.000cst and 30.000cst (for high speed track), very good steering, with heavy oil is dificult to get corner.

any news of the aluminium knuckles???
