Basically just charge the battery and extender, twist on the props and tighten and screw on the propeller guards if you wish to use them.

Forth, the battery is unreliable and apparently made of gold

The battery must have been totally drained prior to getting returned and sitting for who

However - the calibration sequence does not appear to work, Additionally, on our 2nd flight attempt the battery seems to have failed.

The only parts you can get are spare props and a very expensive battery which currently sells for close to $400

BECAUSE IT DOES NOT HAVE ENOUGH BATTERY POWER TO SAFELY RETURN TO HOME!!!

Really disappointed - as this seems to be a well-built machine.
