In a Bell with 2 blades, you have to know where to put the cyclic, put it there, and wait. You will eventually get the result you want, you just have to be patient and wait for it. In a 412 it happens a lot quicker, but with a lot more inertia, it still takes some time to start moving. In cruise flight it's a lot quicker. A more accurate comparison is the 206 vs the AS350, since the weights are more comparable. In a 206 you move the cyclic to where it should be and eventually you get a result. In the AS350 you think about moving the cyclic and you have a result, hopefully not too much. Probably about the same in an MD500.
