My DIY drone flips without command

[Dallen]

Hey guys.

Last month I was taking out my 450 quad for a flight. I began to take off and as I reached enough thrust to get off the ground, the two right motors throttled up a lot more without my command and it flopped over, breaking the props.

My latest shipment of props just came in (after being unsupplied for the month) and I tried again, this time with more care. It still did the same thing.

I went inside and recalibrated my accelerometers, in hopes that that would change something. Nothing. Now I have no idea what to do. ESC, motors, fc, etc.. who knows. Help much appreciated.
Thanks.

HI make sure props are on the right way and the motors turn the right way on an X quad its front left CW front right CCW , back left CCW and back right CW

Was this your first flight?

Those are all the things I checked first.

No, I've flown this many times. Never had this problem. I just recalibrated ESC s. Update later.

Update: calibrated ESCs and nothing new.

Maybe some help here.

Jackson, thanks so much! I didn't even realize to check whether the ESCs were plugged into the right port. Heaven knows how I did that. Thanks so much!
