Governor advice

[pjbrazendale]

Hi all,

Just wondering if someone could explain in simple terms what exactly a governor does and how it benefits you during flight? The reason I'm asking is that i am a newbie however I'm about to start my first build and if I need one I would like to build it in as part of the initial build.

Many thanks

Pete

A gov holds the headspeed at a certain rpm that you set eg for 3d on a 50 size heli i have mine set to 2100 rpm so this hold my engine to its optium rpm you can set the headspeed lower for learing so the heli is not as intemidating and not as lively on cyclic
For learing it is not nessary to have one and without one you will learn to setup and tweek your throttle curves hope this helps you all the best with your build and flying

Governor mode can be really nifty, as it will keep your head speed constant even in a rapid, elevator-style descent (which would normally dramatically speed up your head speed). However, the price you pay for the convenience of a consistent head speed is a loss of power, as the governor sacrifices top-end power for consistent speed under varying loads.

My governor-ed throttle curves are flat 77% and flat 85% on my T-Rex. A full-pitch (10 degree) climb out in governor mode at 77% sees no loss of head speed at all, while at 85% head speed drops about a hundred RPM on the way up. If the power seems lacking in governor mode, just go up one pinion size (11 tooth to 12 tooth, for instance) or try bumping your timing mode and throttle response from Low to High.

Align fixed a lot of things with governor mode on their more recent ESCs. It's not an amazing change, but flying in governor mode feels more consistent and also draws fewer amps over the course of the flight than my curves.

If you have good throttle and pitch curves, you won't notice much of a difference with the governor. If they were way off, you will notice a pretty enormous change in head speed variation.

It gives you and maintains a constant headspeed! When the engine is underload to eliminate or help towards stopping the engine bogging,or overspeeding when descending

Thanks very much for all the replies it was very helpful. I think as I'm learning I will go without one and hopefully learn more that way.

Thanks again

My advice would be if your starting out, leave it off, its one less complication, you wont really need it for awhile, plus less to damage in a crash. It will also allowyou to learn about the throttle curves as you start to use idleup.

But I wouldn't worry about any of that until your past the hovering and playing with your first aerobatics.

Agree with Sesame that is the way to go

I don't know, I think a governor gives a beginner less to think about. You'll eventually end up running one so why worry about tuning throttle curves at the start. Fit, set and forget. I've ran one since I started flying and never worried about curves.

I see both sides, however I do agree with Tony that learning curves means you can back up the Governor because as we know, sensors fail, magnets get thrown etc & this means the governor won't engage. having your curves set properly behind the scenes will make it easier to fly the heli if it does fail.

On the other hand, governor on means you don't need to worry about the curve so as Dave said, less to think about.

I personally only started using a governor when I started moving about and was thinking about doing loops, stall turns etc
