Simple truth is that there is no way to avoid these risks. You can reduce them by using duplicate power sources..you can even use duplicate rx's. You can tape, tie, lock junctions. You can preflight until you go dizzy.. all you do is REDUCE the risk.
Every solder joint, every switch, every regulator can fail. Every servo and every wire can short out and screw your power draw. The fewer your junctions the better.
I still haven't found the cause..but then i haven't taken the thing apart yet. Everything was braided or spiralled. Personally I've found the latest 2:1 regulator fault free on my nitro.. but that doesn't vibrate at the same frequencies.. but has fallen out of the sky because servo splines jumped.
Yes, I shall install duplicate power source here.. But it'll only reduce the risk. I'll still have a heavy dog of a machine with crappy quality century parts that constantly need checking and monitoring for wear and alignment. It's fine if you start out as an expert pilot or never push yourself or risk a ding or enjoy spending your time with a heli on a bench. Even changing a feathering spindle on one of these can involve polishing the brown patina and sanding the plastic ball to get the thing in there (and probably glueing it back on once or twice)... I've done all this often enough now..
On my trex helis the parts costs are cheap enough that anything dodgy just gets swapped out.. and the new bits actually fit and look clean.
