Problem similar to instaflip

[Mark Senderak]

For anyone who can help. I am new to the quadcopter hobby and recently bought the furibee darkmax 220. After having a hell of a time getting the receiver bound to the flight controller I do finally have a successful bind. However, now when I fly it, I get a problem similar to insta flip. I say similar because it isn’t always right after take off and it does not always flip. Sometimes I’ll fly it for 30 seconds to a minute and it will either flip or drop out of the air when I give it high throttle. Other times it will start to fly off balance and become very hard to control just before dying or flipping when I give it throttle. I have been attempting to solve this problem for weeks now and have not made any progress. Anyone have a similar problem or know what this could be? Thanks

Makes me think bad solder joint on the PDB or one or more ESCs.
