The R44 and the Bell 206 have a very good range due to the higher inertia blade systems that these aircraft have.
Not a twin pilot so dont know about BO105 and puma etc - (do they practice autos in those things?)
The bell 47 is very nice in auto. I know a guy that can auto to the ground, lift it into the hover and do a 360 in it before putting it on the ground again - not got the balls to try it myself yet though!!!!
