Review on 💥 iFlight SucceX-D F4 Flight Controller + 20A ESC AIO Whoop Board (MPU6000) - Optimized for Tiny Whoop Cinewhoop FPV Racing Drone Quadcopter, Compatible with FPV Air Unit by Keely Simmons

I bought 2 of these. Both caught fire on my desktop before the first flight. The first smoke through the USB connection from the PC. My USB slot is also broken. Second, I have a smoke plug that I use, didn't stop it, 3s battery, the flame blew out of the board like it was 100v. I've never had this with any type of board. Otherwise I had no problems with iflight products. They say to update the firmware first. But it went off when I plugged in the USB. Couldn't get far enough to update it.
