- I was trying to connect F3 EVO with FS iA6B receiver’s iBUS servo port, is it work?
- when I connect the battery all motors start spinning.
- And I accidently burned the small diode, can anyone please tell me the better replacement option or diode code number??
Sounds like you hit it with reverse polarity. I did that for one of my Alien Fcs (it was OK afterwards since I pulled power very quickly). Not sure about the specs of that diode, but I would triple check your wiring before applying power again
