I know that this has happened to other DF 250 RTB owners, but I would like to make others aware of this problem on a specific thread. The kill switch is secured by a small screw, it doubles as the pivot point as well. There are multiple springs and ball bearings pushing against the controls, if you do not check this one bolt you will find that your kill switch will simply pop off. It will still run but you will have to shut the motor from the key.
