The original q was 'what is the difference between the Astro and the Raven'. Generally the answer is:-
1. Hydraulics (main)
2. Adjustable Rudder Pedals (RHS)
3. Cost (second)
4. Then for the Raven II, different engine, jump start points on the outside of the front console and some rotor variations to reduce noise.
However there were also hydraulic Astros ....
The Astro is also 'discontinued' so most will become Raven I series through rebuild by 2012.
I used to dislike the electric trim, but after 3 years solid flying the hydraulics, I flew a electric trim machine in Australia for a while and it didnt feel so different anymore.
