Bitcraze Forums

I followed religiously the instructions at https://www.bitcraze.io/getting-started ... yflie-2-0/
I checked the propellers rotation several times (according to https://www.bitcraze.io/wp-content/uplo ... _props.png ) and they seem fine.
Turn on, green led flashes five times quickly, propellers turn one after the other.

Connect via bluetooth with the client app, thrust at max, propellers start spinning, everything seems to work fine, but it doesn't leave the ground.
I leave it the whole night charging and try again.
Again everything seems to be working fine, but it just doesn't leave the ground.

If I keep it between two fingers so that it can pitch freely, it stays level.

Hi,

Which client app are you using? PC client, Android, iOS?

Just to double-check, please make sure that you can see a little "ring" on every propeller's center as seen on
https://www.bitcraze.io/wp-content/uplo ... _props.png
otherwise your props are facing the wrong way.

And another test: what happens if you hold the Crazyflie with two fingers at the end of one arm (on the plastic motor mount), letting it hang down and carefully (!) increase thrust? (it should try to turn upright)

HTH,

Fred

Thanks Fred, I had mounted ALL the propellers on the wrong side.
It works now!

Glad you could fix it. Happy flying!
