Default nano qx won't lift off with full battery.

Nano will not lift off and starts blinking like its hit LVC shortly after powering up. Charged battey with 2 seperate chargers to insure they were charged. Ideas? This just began happening.

Bad battery?

Charger have a discharge or storage charge option?

If so set the discharge amps to what the nQX roughly draws and and start with a fully charged battery and check the voltage drop under load.

If the store or discharge ends nearly immediately the battery is done or possibly a connection issue. If it doesn't something in the nQX is drawing more than it should.

Regards,

Steve

If you're confident the batteries are good I bet it's a motor going out. Any of them getting hotter than the others? If you've got a decent charger you can do some testing on them.

The obvious... check for hair or fiber stuck on the driveshaft.... make sure prop leading edges are sharp... if not scrape them with a fingernail until they are. This can really make a world of difference with these things. If neither of these are issues, yeah, it's probably a motor going bad.

Main gear has probably moved down on the shaft.

Had this happen to me a few times,(blinking blue light with fresh battery when trying to take off) in my case it was a loose wire from motor plugging into board. Make sure they are all seated properly.

No gears on the nQX.

Scuffed prop wouldn't cause the lvc to go off so quickly. If not the battery I would definitely check for hair or whatever though, as that could really draw some amps.
