3D printed Quadcopter

Hello Everyone
I have a 3D printed Quad copter that I just finished building. First flight was not a good one. It started to go up then it just flipped. the Flight controller is
iFlight SucceX-E Mini F7 V1.0 MPU6000. The ESC's are Crazepony Flycolor BLHeli S 30A. The ESC's is a replacement from the ones I had before. Thought it mite have been the ESC's problem. Well now I have no idea what it is. I have checked the rotation of the motors and made sure the propeller was the right direction. I used Betaflight to test the motors. Everything looks good. I haven't done a PID tuning yet. I was thinking it might be my Flight Controller. Not sure how good it is. As far as I know everything is wired up right. Oh I'm using the FLYSKY FS-i6x 10CH Transmitter with iA10B Receiver. I'm using the IBUS connection the the flight controller. I can attach the Beta flight configuration someone thinks that would help trouble shoot my problem. Not sure what info folks would need to help. Update just dawned on me. I didn't do the ESC calibration yet. I will do that tomorrow and get back and update.

Thanks for reading.

Yup esc calibration can never hurt, but if the motors respond as expected in the motors tab using sliders though then that should be mostly fine. Some vid always helps can post a private/unlisted vid on YouTube and share a link here. Do some ground testing with just right stick make sure pitch roll and yaw work correctly on the ground (yaw might be jump cause of vibrations but others should mostly work just light on the right stick no throttle).

The FC is a pretty good one but make sure it is "soft mounted" on screws between rubber grommets and that it can move a tiny bit when pushed (nuts aren't too locked down)

Just saying hi... I am using the same flight controller with a 3D printed frame but with the matching brand 4 in 1 ESC (I printed the peon 230).
It is my first build and after I soldered everything up I realized that the motors I used were threaded so that the nut would fly off after throttling up... so I used betaflight config to reverse the motor direction and all is good now... but when I first flew... i flipped like you mentioned... might not be the same issue because it seems like you have had some builds in the past but was just mentioning... just in case...

The motors need to be spinning the direction indicated on betaflight configuration or motors tab near the top there is a diagram the 1,2,3,4 positions need to match and direction needs to match for things to work. You can remap the signals if 1 on motor tab isn't in right position for motor 1 or like you did with blheli configurator or suite can reverse motor direction. Regarding threading unless you buy CW and CCW motors, two of them will be spinning the nut loose. So either buy CW+CCW motors (CW is normal if not mentioned) or just use nyloc nuts and crank them down hard and tighten up before flights.

Basically two motors spin one way (diagnol each other on the frame to same direction) other two spin opposite way so the force of the spinning cancels out when all motors going at same speed.
