What does a governor do for the engine?

[poor_red_neck]

I tried searching, and only thing I can really find is people having problems or setting up Q's about governors, nothing about what it's for.

Now, I used to work on lawn mowers, and I know the governors on those kept them from over-revving.

I'm assuming this does the same thing? Keeps the RPM constant?

Is this something that is required for a 600N, or can I "live without it."

Is this going to prolong the life of the motor? Or more for performance for the "mad 3Dz"

A governor maintains engine speed. It protects against over-revving, and holds a constant headspeed. Is it a must? No. with the proper T curves, you can do the same thing inside the programming of your TX.

Does a gov make life easier? Yes. Can it help your engine? Yes. But it can also hurt your engine if it isn't properly setup.

you do not NEED a gov if you use T-Curves right ,, i just got my 1st Gov a YB ATGv2 ,,, its great no more over reving and sill count on my T curves but have a gov for a safety and will not build a new Heli with out one :thumbup:

There are also devices called limiters that will allow the engine to follow the TX throttle curve but still prevent overspeeding of the engine. Some (most?) governors also have a limiter mode, one example being the Multigov.

I have found that the gov helps make hovering easier because it gives you a constant headspeed which makes the pitch response feel much more consistent (especially on windy days).

I would say get a gov but make sure you know how to set your curves and tune your engine first.

I found the multigov very easy to set up too!

I'm assuming this does the same thing? Keeps the RPM constant?--keeps headspeed constant by opening and closing carb, most pick up the speed based on the engine fan RPM and determine by the gear ratio

Is this something that is required for a 600N, or can I "live without it."--not required, but definitely helpful. I highly recommend you learn how to tune your motor and set up throttle curves before using a governor. You need good throttle curves as a backup anyway.

Is this going to prolong the life of the motor? Or more for performance for the "mad 3Dz"--better performance all around
