Yes the 407.... what a great machine.
I went from having well over a 1000hrs in the 206 B/L into a 407 and glad I did it that way. Not saying that the 407 is harder.... on the contrary. With the extra power and greater instant response from the controls, it is allot easier. Now days I can be flying a 407 in the morning then finish the day on a 206.
When going from the 407 to a 206 it is very easy to over torque. As you will run out of power quickly in the 206 if you are used to the 407. Also the collective position in the 407 sits higher than the 206 at the same percent value. So when you jump into the 407 you will be reluctant to pull the collective higher thinking you are pulling to much, just to look at the gauge and see it sitting at 60%.
Naarr you will love the 407 especially going from a 44 to that..... it will blow you away. FADEC failure.... here is a tip...... react with the collective first not the throttle..... you should move the throttle very little.
I could go on...... You will have no problems going into the 407 but from the 407 to a 206 you will have to be very careful especially if you have a lot of hours in the 407 as over torquing the 206 is easy to do.
