We have used NCC70s without too much problem - but they themselves are noisy and you will need to protect your receiver from them. They have a fair sized chunk of ali in the middle which is the main heat sink - this should be bolted to something metal and heavy if you are going to work them hard. We used the sink as the main mount with the corner holes linking through stand offs to prevent board bending - that worked OK. Then we installed the boards only on the corner holes through stand-offs, and used a finned heat sink mounted to the existing one - result - mounts sheared very easily. So - I would use the heat sink as the main mount but also use the corners too.
I dont know about the 4QD boxes - are they design for robot shock loads? I doubt it.....
Dave, we mounted HANNIBALS pro 120s on a 1/16 ali plate by the pcb heat sink. The heat sink bolt holes were drilled and tapped up a size and the original brass screws were replaced with s/steel bolts. The ali plate was then mounted onto the chassis with 4 rubber/stud mounts. Never had any problems with the Pro 120s but never really been tested accept at the RW7 qualifiers when Disco Inferno went to town on us.
