I use Governor mode on my Align 35G ESC. it appears the functionality of it is that it ensures that at all times, your heli's headspead (RPM) relative to either your curves or stick position is kept constant. But sincerely, i am also not too clear on the mechanics of this, and what the real advantages (or disadvantages) are. Perhaps some of the Guys here at the forum may be able to shed more light. Am also interested.

I use governor mode on my Phoenix 35. To set up your curves properly requires a $120 sky tach. To set up governor mode requires a $20 airplane prop tach which I already have.

The main advantage is that you simply set it and forget it. You'll have a constant head speed no matter what the pitch is. The ESC is constantly sensing the head speed and adjusting it up or down to compensate for the changing load on the rotor. Your throttle "curve" becomes a straight line, the value of which dictates the head speed.

The disadvantage is that the govenor mode in some brands of ESC don't work very well. They either don't react to the changing load quickly enough, or they "hunt" which causes an audible oscillation in the head and in severe cases, will cause the tail to visibly oscillate.

To put this another way: Some people prefer to buy a car with a manual transmission so that they feel "connected" to the road. Others get a car with an automatic transmission, set the cruise control, and simply enjoy the ride.

My feeling is, let the computer chip do the work! :glasses:

Thanks PaulH, i kind of buy your point of view. Could you please confirm if the Align 35G ESC's governor mode works efficiently, do you have any experience with this ESC?

I haven't use any of the Align ESC models. Hopefully someone else can comment on them.

The Phoenix 35 has served me well. I haven't had the time to update its firmware to the lastest version which is supposed to be a huge improvement over the older versions.
