This one little piece... the PDB... weighs twice as much as the last FPV/AP quad I built, and that's all-up flying weight.
35g
including battery?
Pictures please!
I'm having fun debugging this little monster at the moment and it weighs 199g together with the 650mA/h 4S battery strapped underneath or 130g dry. At 199g all-up, it hovers at 25% throttle, so there's plenty of power there for high-speed FPV acrobatics. It's also good for line of sight flight as the outline makes it easy to maintain orientation. I doubt if I could go much lighter than 200g and still have good performance.
(I put the 18650 there for scale and it weighs 45g.) I have a Rotor-X Atom 122 which was 130g all-up and performance was OK with 3" carbon fibre propellers. The tiny 1105 motors I had on the Atom are shot though, so it's awaiting a rebuild. The 35g you are talking about is only 10g more than the featherweight H8 mini, so it would be interesting to see what you did with such a minimal all-up weight.
