[tunaman222]

Can they be put on the wrong way round, so to speak, i.e. giving downward thrust? Do the motors accelerate when you throttle up?

You'll notice on tips of the propellers there are silver bands.

Looking down from the top with the drone facing away from you

Left front props - single band
Right front props - double band
Left rear props - double band
Right rear props - single band

so basically, diagonally opposite each other needs to be matching bands

To confirm what what @lannes says, there's also markings (or no markings) on the props and on the motors.

Here's a page from the manual and a link to it. USER MANUAL PDF
