ZMR 250 multirotor dropping out of the sky

Quadcopter losing control and dropping/flying strait into the ground



can anyone help shed any light on whats going on? I have a 250 size ZMR quadcopter it flies for the first minute but then when i take it to any height it loses control and doesnt respond to the controller and just banks any way and flies strait into the ground. i thought it was the front left motor so ive replaced that but really not sure what else to do. (i'm new to all of this.) any help would be appreciated. thanks

this all seemed to happen after a few crashes.

  • It looks like you lost radio control. You might have a bad receiver or transmiter. Take the props off and get someone to help you do a range check.
