This post is an update about my 4in1 blheli_s ESC tinyPEPPER. I just did a first test using an old F3 evo brushed board that i converted to brushless operation (remove FETs and pulldown resistors). I will probably to the maiden with this board and an uSKY rx instead of using my tinyFISH fc as it is not completely soldered yet.
In this test i played with the throttle sliders inside the betaflight configurator. All 4 motors spin up nicely. The previous reset on big throttle steps was solved by a small pcb layout change — yay!
