I'm so mad

I Had my heli for about a 18 months and I was told it's a good idea to change your switch harness about every year or so for cheap insurance well last night I but a NEW Heavy duty switch in and about a half a tank flying inverted about 20ft up she goes nuts strait into the ground after looking at the wreckage my New switch had a bad solder joint cheap insurance it cost me $$$$
I guess I'll check more closely at my harness before installing them
