This was a tough build, lots of tiny screws in tiny holes with tiny solder joints...and it flies! Had problems with the first FC I had chosen for this so I ended up having to use the FuriousFPV Racewhoop which doesn't have an OSD. The first no-name FC that I got was defective, it would disconnect on USB and start burning when the ESC was plugged in. I suspected the ESC so I returned it and tried again. This time everything worked great...for a little while. Had the FC updated and all configured, motors all tested and rotating right, RX bound and modes setup. Then when I plugged in fresh batteries for my first hover poof, the magic smoke came out. I abandoned that FC, kept the ESC and got the new Racewhoop. It worked first time. Updated to BF 3.2.4, updated the ESC firmware, everything works great now. I'll update once I test some more. Not sure if I would recommend some of these parts, I'll let you know.
Very nice! How have the aluminum ducts held up?
Just fine so far. It doesn't get as much indoor flight time as my brushed whoop but so far I haven't had any issues with it.
