blheli 4 in 1 ESC

Introduction: It is too difficult to make this thing. If the chip is soldered at a high temperature or takes a long time, it will become useless. After everything is done, it will burn out within 1 minute of taking off, and the capacitor will smoke. Then after eliminating the short circuit, I found that all the chips were burned, but the MOS tubes were all OK. I don't recommend doing this crap. If you want to do it, give the smt to Jialichuang
