Why not a turbine engine?
Why are we constantly using piston when turbine is lighter, more reliable, less complex?
It may be more expensive initially but in the long run?
I met a guy not too long ago that has a TH-55 that is puttting a gas turbine engine in that was designed for a military platform that got canned.
The engines ( he bought 4 ) were brand new still in the ole bubble wrap, were being used for gen sets.
Blades were composite design.
Lots of weight removed, quieter, more power & reliability in place.
Carry bigger pilot folk & more fuel for longer flights.
Going to be registered under experimental.
So why not I ask a light/training helicopter?
