I will ask him pa. 6k daw pakabit nya. hmmm... basta may maliit na match-box size thingie with led lights tapos all through out the undercarriage, maraming mga "nodes" na connected with wires (probably to distribute the current evenly). sorry bro di ko pa talaga alam ang details kasi hindi rin sila nagkabit (tho they have a talyer).

his undercarriage is not painted or chemically rust-proofed.
