I find that the wiring gauges found in tank electronics are pretty small and not really suitable for repeated handling. I have broken the wire at the crimpled end of my Tamiya's gun flash unit multiple times just removing the plug. But its just probably me being ham-fisted - but the Clark electronics have pretty thin wiring as well that the guys back home have quite a few reliability problems with. I think the larger JST connectors are more durable for repeated unplugging than direct board socket connections like these - of course, they will have to be color coded to prevent a disaster.
