@Peter PanPan ... I absolutely agree with you, good sugestion
One more...you can do it on aeroplane, if you have PPL-A for example...for 7500 € (35 h FNPT plus 15 h aeroplane). Or, plus aditional 8000 € (or less) with PPL training (35 h) and 5 hours of Night Q...if you don`t fly aeroplane.
After everything, with type rating on ME helicopter, you need 10 h of transition training, from IR/SE(A) to ME/IR(H)!
