Feigao 9L Question

[Serum]

Foam stiffer than the foam in the tires, i don't know where to get it in the US, here i buy it in a hobbystore (for creative children) it comes in sheets in about 3mm thickness

Normally those SMD parts can be weld back in place, just find the place where they sit before and easy weld them back in place with the smallest welding tip you can find.
