Helieagle - why do you not want to do this?
At our place, the engineers (plural) swarm all over the machine, and we do a preflight every time, though I'm still not used to not having to untie the blades by myself
I can't ever see a point where I would not do my own preflight, no matter how many people have looked at it before. The preflight is not the same as a daily check, either - treat it as a last line of defence against a mistake before you fly - you can never check the machine enough beforehand, as long as you don't get obsessive about it.
We had the ridiculous situation in UK in my previous place where the CAA were quite happy for pilots to do daily checks away from base where there was no engineering support, but not do them at base where there was an engineer.
