I hear you loud and clear. The EPS foam planes are made from the same material they are packed in, pre-expanded or non-expanded polystyrene, and the cost is minimal. The molds are cnc carved from wood or aluminum based on a scaled file, modified to house our fans, ducting, servos and packs, then fiber-glassed and coated with a release agent. The packaging was made the same way. 550 Grams of bargain basement EPS beads enters a heated hydraulic mold and suddenly turns into $200. I don't get it.

Motors are the same. A piece of round stock aluminum enters an automated lathe and is machined. Two bearings are pressed inside and a precut or molded armature is wound in sub assemblies and is interference mounted by hand of machine. The bell magnet housing and shaft are press fit, repeat for next motor.
