Out of pure curiosity: what is the cheapest/smallest helicopter known first hand by a member of this honorable community to be single pilot IFR certified?
I've seen a BO105, was today PAX in an IFR EC135, no big deal. But are there say MD500s that may do SPIFR? Or JetBangers? Or even piston powered types like Hu269, R44
?
TIA
