Yeah, i was a pilot/tech for 5 years, mainly on a super scorpio but also on that SMD Quantum.
Had a week with Slingsbys getting trained on rebuilding manipulator arms too, that was good.
Would that be an automatic reply then? haha.
When i say these are not home built.... welll, i did a lot of the build work on the top one. try finding a wiring fault in something like that when all the wires are white!!!!
