Hello guys, I appeal on his vast experience for a suggestion and advice, I'll do an update of my cinestar 6 to a heavy lift , I want to continue with the mikrokopter electronics but without the PDB, using the I2C converter for commercial ESC. What motors and esc recommend me, from the cheapest to most expensive. I have FC 2.1 with Acc upgrade and use 4s battery with QC3328 motors. Thanks for your comments and help, Gustavo.
