Hello everybody,I'm working in my first quad and i a little desperate because i can't make it fly. For a few weeks i'm testing everything but can't make motors work.So, i've uploaded the firmware successfully (although it says it couldnt be verified). And i guess PDB is well solded. I've tried different connections yesterday and one ESC just blew up, with smoke and everything. i have some questions now:How can i now if Ardupilot is still ok? before i had like 3 leds and now jst 1 red.I never…See More

PDB Help

Hello everyone. I'm having some troubles concerning the quadcopter assembly. In this phase, i am testing the system WITHOUT the Arduino. Firstly, i started testing each motor individualy and everything went ok. Then, i tried to use the PDB and this is where i have my problem. Nothing happens, no noise from the ESC's. I am connecting the ESC's to the RC receiver and the battery to the power input in PDB but no signal. I guess that everything is well soldered. Thank you a lot!See More
