Hello I can fix the parrot minidrone spider. 1. If parrot minidrone is not connected with bluetooth then finish it by removing battery then plug it back and on android please turn on bluetooth then let stand until connected, more or less only 20 seconds. 2. If the minidrone parrot flies unbalanced then the vane is removed all and then reinstall it with scramble position, if still can not fly then random re-installation of the propeller. If any more needed more please please whatsapp me +6282114465668 My name is Sultan Fajar from Jakarta, ID
