Hey bugdevheli,
I am helicopter licenced engineer and fixed wing rated private pilot (hope to get my rotary licence soon!)
I think a pilot who is engineer as well will always be cautious and more suspicious than a pilot without (that much) technical knowledge. Everytime I fly in an aircraft (no matter if fixed or rotary wing), I automatically listen and watch for anything that is wrong. It's not fear or anything like that, I really enjoy flying. But you just always expect something to happen. Maybe that's bad for me, I don't know.
Nice regards,
Chris
