The Lafhelicopters tandem design is so different to all other design concepts that to now fail due to funds is a loss to the rotorwing business.
Sure there will be many modifications to the design before it becomes commercial.
Sadly I do not have the required funds but somewhere there ought to be.
Here in the UK we sadly lack any enthusiasm for risk BUT have the Lafhelicopter team tried here in UK.
Such an idea should be persued to prove or otherwise the feasability of such a design to provide safe, easy to fly and relatively cost effective rotory flight. And yes get rid of the automotive engine and go for a single diesel or cosider a twin engine concept.
