The voltage input wires fatigued and broke free from the PCB. The second one was be caused I mistakenly used a receiver that had been crashed. These are what I call self inflicted failures. My current gasser would keep some guys awake at nite. The RX batteries are 2" away from the ignition, the throttle servo is 3" away from one of the plug wires and 1.5" away from a header. I use a Tech Aero IBEC. This airplane has about 40 rock solid flights. Part of that success ( although quite early in its lifespan) is that I'm using a power expander and all servo and power leads are twisted. Twisted wires are a subject of debate however even if there is no benifit, there is no downside either. Being that I have been flying models for 36 years, I can honestly say that these days I see far fewer radio related crashes then ever before and I see far more poor installations then ever.
Just about all my radio gear installations since I started using 2.4 include at least the throttle servo and batteries placed within 3 or 4 inches of the ignition module as illustrated in pics below with no issues at all. I have done this in several airplanes now so I don't suspect that you will have any issues with your installations either. I too see more poor installation on everything these days then ever before, that is why I made the statement a couple of posts back to use the best shop practices when installing whatever in airplanes. I know you have probably seen these pictures before but others may not have.
