Hello Everyone,

I am currently flying an Align 450 SE v2 heli and was wondering on the governor mode for the Align ESC 35A. What are the advantages/disadvantages of using the governor mode? I am currently using the recommended pitch/throttle curve from Align for the bird and haven't tried the governor mode yet. How do you properly setup the throttle curve for governor mode on the transmitter?

Thanks.

Hi,

I have also had same intrigue except I have a Castle Craetion 35A ESC which has governor mode. I currently fly with programed throttle and pitch vurves. The latest updates on the castle creations ESC has made substantial modifications and several governor mode options for Helis but not sure how governor mode benefits. Someone told me that you waste more energy from the battery pack but didnt explain why. Some one else told me that in idle up ussing standard radio programed pitch and throtle you should not attempt hard flairups etc as can cause had linkages to snap out and that to be able to do hard flairups you required the Governor mode to be implemented.

If someone has experince with governor mode esc settings would be great to learn benefits adrw backs of implementing them.

Thanks

I tried the gov mode on the Align, I found it flew much better w/ throttle curves.

What happened is the esc would pulse the motor, constantly changing the torque and giving the gyro fits not to mention I'm sure its one of the reasons my tail belt shredded in 5 flights. After switching back to non governor mode all was well.

I've heard the Jazz governor mode works but thats the only one I've heard of working well.

When Trextuning did a reveiw on the Castle Creations Phoenix 35, they said the govenor worked great.

The Governor does for throttle what a gyro does for your rudder. It effectivly converts your throttle control from varying the motor power to varying the absolute head speed, just as a headlock gyro turns the rudder from a rotation rate control into an absolute possition control.

The throttle and pitch curves in your TX are for matching pitch to input power to give a constant head speed, but there are many other factors which will also change the required power which these curves do not address.

It is important to maintain as constant a head speed as possible for the controls to behave predictably. As head speed slows down the elevator and ailerons become less effective and more control input is needed.

The governor constantly measures the motor speed and compairs it to the comanded speed from the reciever. The throttle curve should be set flat (apart from the zero throttle possition) at a level that gives the required head speed.

You should also match the drive pinion size so that propper head speed is reached using about 85% - 90% throttle. The faster motor speed means it is pulling less current and should run cooler and more efficiently, while still leaving room for the governor to add power as required to keep the head speed constant.

Thx Karin,

Do yuou fly a Trex in Governor Mode? What head speesds are recommended in iddle up for soprt flying and for 3D?

Thx

Your max head speed is limited by the rating of your blades. The "standard" woodies and CF ones that came with my SE were both labled as 2400rpm max on the package. I've read about people going up to 2800rpm and beyond for 3D. The faster you spin them, the sharper the response from the controls.

So this is another advantage of using governor mode, you can run your blades to their limit with much lower risk of over stressing them.

Thx Karyn,

I am ussing Maverik CF blades 325mm. What rating would the Head speed be for those on 3d?

I can't help with specific rpm numbers for different blades, I don't have that info. Sorry. Does their web site have any info? Does the packaging that they came in have any info printed on it?

I think most people run between 2200 - 2400 most of the time. Larger blades will give more lift so you could slow them down a little, but not by much
