Arkroyal : "Two engines (turbines) please"
And what makes you think this configuration will save your life ?
All that weight, all that fuel, all that complexity, all that extra stress - all that BS.
All that - and when your no.1 goes, no.2 will fly you to your accident.
When will this myth of "2 better than 1" finally be wiped out ? It is perpetuated by those who have not a care for the costs of helicopters - and a blind eye for statistics.
