Here’s the BoM and some details for the components I’m using for the OhMini quadcopters. The big expense is getting all the basic support gear including radios and charger and cables/adapters, but once you have all that you don’t need to buy it again for each multirotor you build. In my case all this stuff is about $160. The quad itself less RX is about $100. I’m using a $18 RX but for this simple quad there are cheaper available, even one for $6. It just has to be compatible with the TX.
