@Graeme Smith I'd like to have a reliable shaft-driven TR drive and gearbox system instead of all the belts! However, reliability and cost are big considerations. Your upgrade will have to prove itself over many flight hours (I'd say maybe 2,000 combined hours between a few helicopters) without issue before I would consider the switch. I think about the early turbine conversions with the various drivetrain issues or the heavily-modified rotorways that usually sit on trailers at fly-ins instead of flying.
Until then, I won't consider deviating from the factory design. However, I commend you on working with engineers to improve the design and I hope it's a success!
