Tungsten weighs 1.7 times more than lead! Only gold, platinum, and a few other precious metals have a similar density. Tungsten is also completely non-toxic and environmentally friendly. It's a really hard metal, and will last for years. It's a nice one time investment.

These plates are 99.97% pure tungsten! This plate is 1/16" x 0.55" x 1.42". They weight 0.5 oz each. It will fit under your speed controller, receiver, or LiPo battery. Although they are 99.97% pure tungsten, the surface finish for these short plates is not as good as the long plates. Some slots on the chassis may need to be opened up with a file just a hair.

These are sold individually.
