Make sure you're blades are not damaged. Also the manufacturers manual that came with it normally has instructions on how to recalibrate.

Thought it might have been my phone or WiFi causing interference. Seems to drop In certain spots....more so when I had my phone hooked up on the controller

You may have to, To replace the motor and replace it. Just look up videos online for your drone. Scary the first time, easy after.

Having the same issue myself.

Seems to auto land for some reason, Flew great first few times. Now it'll drop at random times.

I have been searching for a fix. I'll post it if I find any.

Also try flying without the app on. Mine worked for a couple flights without it.. seemed to interfere with the antenna or lack of.

Need a new battery. Depending on the drone, they're not hard to come by. Normally on the manual or box it came in has a website for parts. Or you can try amazon.

Turns green normally when it's fully charged

Okay. So I have a sky viper hd2400, thing flew great first couple times. Now it seems to drop at random times during flight... I'm thinking I'm out of range, but the first couple times It flew much further before dropping. Now it's doing the auto land even 7 feet away 'sometimes' other times its fine.

Any idea?
