used it after almost 8 months..thouight that the 11.1 v lipos might have also conked off because the drone refused to lift off .so brought a brand new lipo and charged it also.but again the same thing,the drone doesnt lift off.i hjave recalibrated everything on the nazam inclusing my remote controller which shows all ok.what can be the issue.are the motors gone.

everything is original including props..all dji.opened the controller..no loose connections.cant attach video.checked the drone thrust by holding it in my hand as i fired the RX to full power..theres absolutely POOR  thrust developing.i remember earlier days when i have launched and recovered this drone by hand..that power/thrust is gone.earlier times on powering up the thrust was intense and required huge effort to hold it in my hands.the batteries are purrfect.are the motors gone..drone must be a decade old

ok...corrected it now..was using the wrong joystick..allas well now..drone flying ok
