Hi Aviral, that story sounds extremely familiar with an event I had when I made my first drone. Put simply, I installed the incorrect prop on one of the arms. After applying throttle, the whole drone tipped. It destroyed a VTX and damaged my GoPro, I wasn’t too happy. It may change depending on the Flight controller, but you should have a prop rotation layout like this.
I hope this helps.
thx

Trust me ash… I checked the direction in which the motors are rotating…is there something wrong with my propellers…? And I have seen that one of the propeller gets loosen after some time…
In my experience, I would suggest you relook at the props your using. Are you using the stock DJI props?
Hey aviral,
Im not a pro at this types of drone but:
Did you checked your motor directions?
Is your Accelerometer calibrated correctly?
Did you checked that your Connections between Radio - Receiver - FC is working properly?
May it possible, that you have soldered wrong or have a faulty part?
Are your PIDs ok?
Also check your Propeller tightness…
If you say that your prop came of… You didnt tighten in well…
