Hi @flyingdragon , I’m using HW PlatinumV4 120A on this heli, so followed the connection scheme reportep on their manual, connecting Yellow cable to rpm input of the flight control:
I Havethe same ESC, 130A platinum OPTO V4 and 200A OPTO V4.1
both have yellow cable also on the side; where is the Fan plug-in gose; the yellow cable for sending the Telmetry info to the FC.
now the yellow cable you used in the pic is for Governing RPM, this will go to the GPIO’s aux Ch?
I need to read the link you provide it to set everying correctly.
