Can anyone advise possible cause,
I looked at your other postings and I noticed that you asked about a "Broken Drone" is this that drone?
I do not own this model of drone but from what you describe, it sounds like the propellers have been installed incorrectly. Perhaps you crashed your drone and broke the propellers and that you have installed them wrong.
I suggest you hold the drone in your hand very securely and start the motors, do you feel air from each motor blowing down?
The placement of the propellers is critical and they rotate in different directions to maintain the stability of flight and if they are installed incorrectly, the drone will flop around and act like a fish out of water… Sound familiar?
This video shows how to install propellers on a drone similar to your, but I would suggest you read your user manual for the exact markings…
A YouTube Video about your Drone…
IF the propellers are not the issue, please write back and see if we can offer other possible fixes…
Good Luck!
