Could somebody explain why he insists on using bullet proof material to make the body? He could have picked simpler and cheaper components/materials. Is this a common practice for higher end quad-copters?
- hayksaakian 13y agoPolycarbonate is used for many things. This is the equivalent of saying he made it with a (commonly used plastic) * 10 * $fluff.
- Dylan16807 13y agoConcrete's bulletproof too and you don't see people calling it complex or expensive.
- utopkara 13y agoYou have a point. Let me rephrase it. There are $40 quadcopters which use weak, yet easy to replace parts. More expensive parts and materials are usually easier to work with as well, so for a prototype they are well justified. But for a production model like this one, is it a product market choice to go with expensive parts, or does the cost of designing for other materials outweigh the risk of going to the customer with a more expensive product?
- gvb 13y agoCDs are polycarbonate and are sold for $20 for a spindle of 100. At a pretty good profit. "Bullet proof plastic" is just marketing buzzwords. FWIIW, polycarbonate has to be quite thick to stop a bullet and is generally used in conjunction with glass. Looking at the chart[1], it is clear it will only stop relatively lower energy handgun bullets, not high power rifle bullets. For that, it requires a glass + plastic laminate.
