I've had electronics issues, some self-inflicted, some not.
Out of the 60+ Freewing servos I've had, I've never had one outright fail. I've had one FMS servo failure out of 50 or so in a tail retract, that was my first "cheap mass produced" servo failure, outside of a crash. I've lost one plane to a brown out, but I was running the ESC at the edge of it's capabilities (self inflicted). I've had exactly one receiver issue. It range tested fine on the ground. In the air...had issues and was lucky to get the plane back. I've had to swap out a number of retracts, particularly the rearward retracting Mirage nose retract, but I'm not flying off smooth paved surfaces and also have to deal with sand gumming up the works and learning to fly EDF jets too. I don't know many retracts that will hold up forever in those conditions and usually it still works, just stalls out trying to close the spring-loaded door. I look at replacing it as just a cost of flying.
Overall though, the electronics in these planes are pretty reliable in stock form. If they run for the first ~hour without issue, and pass initial checks, they're likely to outlive the plane barring damage or abuse. Now if you go over and above stock, and are reducing the margin(s) as I have at times, then all bets are off.
