Generally speaking, for a good build, the most expensive part is going to be the motors and the ESCs.The Emax Red Bottoms, DYS Racing Editions, and new ZMX motors are all around $17-20 per motor.Couple that with decent BLHeli_S ESCs like the Sunrise Cicadas or DYS XS20s, you're looking at another $13-14 per ESC.So when I saw these motors on Banggood for $28 for a pack of four motors, I was intrigued.These are RacerStar 2205/2300 motors. They won't have quite the punch as the Red Bottoms or DYS for sure, but they'll still have decent thrust.Besides, for $30 for 4 motors, why the heck not?So I began thinking - what's the cheapest, yet most performance for the money quadcopter I could put together?I'd only source products on Banggood or Aliexpress, and this is a quadcopter complete with FPV gear and a receiver.Here are the parts(I'll be listing the frame last):With these components so far, we're at $167. Not too shabby! Only the frame left now.If you wanted to cut costs even more, you could get a D4R-II receiver instead of the SBUS receiver, which would save you around $5, bringing you to $162.You could also forgo the HUBOSD altogether and get a regular PDB(although it's most likely you'll get a PDB with your frame).
