For testing indoor is BAD - get outside with a clear view of the sky and plenty of space. Take off more rapidly, get it up in the air. If that works change into a GPS assisted mode.
Got solution !!
one of my ESC got bad it throws very little power output. when one of the capacitors fell out from the esc then only I noticed. Thank for the replay.
Yeah, that was the problem.
For your next upgrade get BLHELI32 / AM32 ESCs so you can use DSHOT and get all that sweet data from the ESCs. Then probably MasterAirScrew MR series props
Holybro are already selling ESCs with AM32 since BLHELI32 is discontinued.
