Im looking for a 1cell brushless setup for a wgt car, Im having trouble and could use some help/recomendations. What ESC will work on a 1cell Lipo?

The Mamba Max Pro 1-cell is, as the name suggests, made for 1S-6S LiPo:

All of Novak's speed controls were designed for low voltage operation, such as 1S or 4 NiMh. Our controllers specifically designed for single cell operation are our budget Havoc 1S with built in SmartBoost circuitry and our upcoming Kinetic 1S, shipping in two weeks.

Tekin rs works well with 1s and I think the new nosram even has a bec at 6 volt so it must boost it some how
